Yeah this vid is good if you don’t want to live in reality because you do realize that Einstein used another theory called gravity in his conceptual theory you can’t make this stuff up to funny. And people buy it hook line and sinker maybe it’s because people have given up their minds and their god given right to think for themselves.
@@shelby3347 You appear to have misunderstood something about Einstein's theories. Gravity is explained more accurately and can be predicted more accurately with Einstein's General Theory of Relativity than using Newton's equations especially when considering large masses. General Relativity takes into account changes in acceleration. Special Relativity explains the fixed speed of light in a vacuum and it's consequences for time and space.
@@marksimpson2321 thank you for showing your ignorance of science and by the way you never disputed anything I said. You interjected mathematical construct into the convo , math isn’t science it’s a descriptive tool of reality and non reality. And light in a vacuum ??? Where on earth literally is there a vacuum in nature ?? There isn’t any. And it’s people like you who prove what I said in my original comment don’t believe me ?? Well let’s settle it real quick and simple please provide me the experiment that backs the claim of Einstein’s theory and it is a theory ( not even a good one ) built with mathematical construct and pseudoscience. And by the way it’s been changed at least 15 times since it’s conception but you probably knew that right ??Your priests are telling you for the last 5 years that gravity isn’t a force. George Musser 2019 “gravity isn’t a force but we can think of it as one” Brian Cox 2015 “ gravity isn’t a force at all” So I’ll just need that link for the scientific experiment that proves Einstein theory thanks.
I am failing my high school, failing to get into desired colleges, failing to get desired jobs... I'd say I'm on track to be the man of the century :'D
It’s a watered-down vision for children. Relativity is the Truth and nothing can exist apart from the Truth! Amen! Reality is darker! This video only talks about two or three phenomena consistent with relativity. What about black mass? What about dark energy? What about the total incompatibility between the mathematical and therefore continuous relativistic view and the discontinuous view of quantum mechanics? What about the Sagnac experience? What about Professor Allais's statistics? And so on and so forth, and some of the best! Check out the list in the video: the collapse of physics th-cam.com/video/QA5b-moh4o0/w-d-xo.html
Superb, as usual. Here is Einstein himself, describing relativity: "Sit with a pretty girl for an hour, and it seems like a second. Put your hand on a hot stove for a second, and it seems like an hour. That's relativity."
@@alexandertownsend3291 It would last forever, because you would chastise yourself why you behaved so stupidly in front of the pretty girl. Doesn't cancel out.
I once dated a girl online, our first meeting lasted for about 1 hour but for me it was like 1 day,.. can someone explain this in theory of relativity..
I will write here that Arvin Ash is wrong that Einstein was the first to put all this together. Many of the 'original' ideas presented by the 1905 Einstein paper was all established by Poincare in 1902 and years before, and stated more completely. Einstein refused to acknowledge Poincare until much later, in fact he has a history of being called a plagiarist due to his lack of crediting others and pretending the ideas were original. Physicists have not done their research on how relativity was constructed so they have perpetuated the Einstein myth, despute there being a completely valid reason why Einstein did not receive a nobel prize for special and general relativity.
I know you trying to sound sciency but using velocity in that concept is just malapropism his thoughts do not have a direction although you could say he thinks fast so really speed makes alot more sense
I've watched many videos /documentaries on the subject and this is the best one I have ever seen.. the present/illustrations/examples are expertly assembled and intuitive.. congratulations on the excellent work.. explained simply indeed
@Valeria Taylor I'd love a link to this assertion, please. I've read a lot of Einstein's work and haven't come across a statement such as this. Thanks in advance for any help you can give me,
Justa Fool Oh, so you were actually serious. Then I will note for now that you seem to be confused. I mean, I think a lot of people would notice your points and people have tried to debunk the theory, so try to rewatch. If you are still confused, I am not able to help now, but maybe within 12 hours?? I will probably forget tho, so no promises.
Justa Fool Ok, so maybe I was overestimating on the time but here is my explanation. Einstein says the equations are identical for all inertial frames of references, not the actual values of things. Also, in regards to the observer field inconsistency, the field does not have a speed, because if it did, it would be relative and make the speed of light relative, which Maxwell did not calculate. So just try to better understand this idea that has predicted many phenomena and given real experimental data. Even if the assumptions are slightly wrong, it is science and it is the best we got. I think most people recognize almost all our equations are somewhat wrong but they are the best we got.
@@funkyflames7430 No, Im not satisfied with the rather lame and child like explanation that "its the best we have got". If you think that einstein's is probably wrong, but we don't have a better story, well that's not sufficient reason to overturn classical physics which does give 100% accurate results. Also, SR is NT the best explanation by any measure! Its probably the crappiest explanation ever proposed! First of all, its an explanation or a solution for a problem that does not actually even exist! Its all make believe. Where exactly does Einstein say that "the equations are identical for all inertial frames of references, not the actual values of things". ? If the equations are the same, and you say the values are different, then the only conclusion must be that what you measured to get your values MUST not be what I was measuring. Try measuring the same things please, then you must always get the same values or results as i get, because we are both using the same equations... 2+2=4 here MUST still equate to 4 over there, because physics and math MUST remain the same in all frames. so no, if you get 2+2=5 over there, then you are not applying the same physics laws. If your answer of 5 IS REALLY TRUE, then this is PROOF that physics is NOT the same in all frames! Make up your mind, pick a side and stay with it. Is physics the same in all frames or not? "Also, in regards to the observer field inconsistency, the field does not have a speed, because if it did, it would be relative and make the speed of light relative, which Maxwell did not calculate." How do you know that "the field" (what that is no body knows) is not moving? This CANT be correct, because that would then comprise as the ABSOLUTE stationary frame of reference, and Einsteins expressly forbid any such thing. So, no, you cant claim that "the field" is stationary, rather must be moving too, and its relative to everything else that's moving, or else Einsteins is wrong right here at this statement. Maxwell never calculated a moving frame because he already assumed a stationary aether, which was his belief. Einstein contradicted Maxwell because he said that Maxwells equations are not invariant when motion is involved. To make Maxwells equations invariant when motion is involved, Lorentz suggested that things shrink in the direction of motion, and that "explained" the M&M experiment's null result. Einstein just took it from there, but proposed that we can still have no aether, no absolute stationary frame of reference if we just say that Time also shrinks. What an idiot. Maxwell in fact never suggested that light speed was a constant in all frames of reference, neither did M&M ever suggest this. Maxwell said that light speed was in fact relative to the medium, and so did M&M. M&M could not find any measurable medium, and Maxwell never even bothered to look. So EInstein's solution opposes Maxwell in one claim. Maxwell said light is constant "relative the medium", (being the vacuum, or water, or air, or glass, or plastic) but Einstein said that light is constant "RELATIVE TO ANY OBSERVER". This is clearly an irrational statement by a simple minded person, not a genius.
@@xiaoxiao-kg5np if you want to learn then you must leave behind your arrogant nature and your pre existing reasoning and go for the full details and then only start to make some analysis. Everyone finds it (SR) super confusing and somewhat unintuitive (not as much as QM though) but the postulates and the predictions of Special relativity has been tested so many times and proven in it's favour, it explains the nature of nature. What more do we want? If you find the theory not compelling then you might come up with one of your groundbreaking ideas, which we are all waiting for. Stay motivated sir!
Great video.Perfect understanding.Time did it in.Mass is not absolute.Now everything is clear.Never felt so delighted.Clear voice and excellent explanation.
As a math lover who doesn't remember much of it from college, this video is peerless. I have watched dozens of scientists discuss this subject on TH-cam and other sources; they covered the same ground as shown here and were superb for the most part. But this presentation was over-the-top, at least for me. The reason I say that is because I feel like I can explain this one concept to another person and actually have them understand it to a significant degree. I could never say that before. Cheers
It really is mind blowing stuff, and I truly appreciate you, for simplifying this and other complicated subjects. Knowledge is power, and if we take it slowly, the things we learn from your videos will help us to understand the world we live in. I have subscribed and look forward to your next videos. Great work.
I am taking a high school physics class, and for our final project we have to research a modern physics subject. I am researching relativity, and your videos have been helping a lot. Thanks for the great content.
manurmad, The theory of relativity is a complete lie. It is based entirely on convoluted and deceptive mathematical models. Nikola Tesla’s statement about the modern methods of scientists like Einstein is revealing. ‘’today’s scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality. Nikola Tesla was the most brilliant scientist and inventor of his time. So advanced were his discoveries that upon his death in 1943 his research papers were seized by the FBI and classified ‘’Top Secret’’ at the request of the U.S. War Department. One of Tesla’s most notable discoveries was alternating electrical current (AC) that is today used to power most homes and businesses. Tesla understood true science and knew a scientific scam when he saw one. In 1935, Tesla called Einstein’s theory of relativity ‘’a magnificent mathematical garb which fascinates, dazzles and makes people blind to the underlying errors. The theory is like a beggar clothed in purple whom ignorant people take for a king…, its exponents are brilliant men but they are metaphysicists rather than scientists.’’ plagiarization is intellectual theft. the unimpeachable record proves that Einstein was not a genius, but was simply a very clever con man, with powerful backers. Gwynne concludes that ''the truth about Einstein is that he was no more than a puppet.'' Gwynne presents compelling evidence that Einstein was selected to play the specific role of refuting the Michelson/Morley experiment (which proved that the earth was motionless) and reestablishing the rotating globular earth. and Time magazine actually put him on their cover and named him the Person of the Century.
I enjoy my vacations but I always miss not being able to watch my favourite TH-cam channels. I thought I had a grasp of relativity from my school days, but i was kidding myself, I didn't. Today I have a much better (but not complete) understanding. i'm working on the missing bits - thanks Arvin.
Sir,I have watched some of your videos.Your explanation is simple and any Physics enthusiastic person is able to understand. You are explaining, even Relatively in a possible and simple way.I am addicted to your videos.
Maybe some scientists before him thought about solving the speed of light problem by suggesting "time must be relative", than abandon the idea because the idea that time flows slowly or faster for others look absurd. This is why it is good to be openminded and think outside the box.
Technically what is "relative" are not space and time, but all of physics is relative, i.e. phenomena only depend on the distance between two objects and their motion relative to each other. They do not depend on something "absolute" third. This was already known to Galileo.
Just to say Arvin Ash's video's depict abstract scientific theories brilliantly. As in, no other channel I can find has 3D models of spacetime. They all use that trampoline curvature of spacetime but it does not give the general public the right idea of the full picture. They still don't know what spacetime is, or means, or its relevance within their own lives. Great job!
That was a very good foundation. The idea that high speed astronauts come back younger, the twin paradox, sums up the mystery of relativity for most of us. It would be brilliant if, in a future video, using a just a bit of maths you could do an animation showing visually why the time dilation must occur and where the time for the astronaut actually gets lost. I haven't seen any really convincing ones and I know it would be very difficult because there are several different theories why it happens, Einstein linked it to acceleration, others didn't - big mystery.
An excellent piece of work to physicists. For a layman like me, a retired biology teacher, I try to explain this way to the general public. The speed of light is known to be constant for different observers. An observer on the ground sees the speed of tennis ball by suming the velocity of train and that of the ball. The observer inside the train sees the speed of the same tennis ball by that tennis ball alone. But if on the train, a beam of ligjt is projecting, the ground observer would see the speed of light the same as the observer on the train because the light insist on the same veolocity to all observer. There is only one equation to calculate the speed of everything, length/time. Therefore in order to let the light keeping its constant speed, the length(and time, they change together though not in direct proportion) of the train travelled has to be flexibly experienced and spacetime dimension(in length travel) has to alter in that reality. This is an incredible conclusion that could stunt people around. As they immediately see the length of the 3D space are flexible or elastic, so connecting to the concept of spacetime being warping around. Of course, Einstein another achievement is figuring out the relative velocity of spacetime into pythrago's theorm of a right angle triangle for the train, the light and the ground observer. Layman could then understand the quantum related area because the emptiness is in fact something a 'fabric' there. Before when vacuum is emptiness, then there is nothing important to particles travel here and there because nothing in between. Since now there is a fabric of the universe which can be twisted, scientist had to find an explanation of how and why they come into existence, why they travel with different spead, even the sperpositioning, quantum entanglement, dark matter, dark energy, vacuum catastrophy, the black hole features, holograpgic universe, multiverse etc, finally pointing to a possible way of solving out the ultimate physics problem of the interaction and creation of our own universe! Of couse, the String theory, Field Interaction, knownledge from backhole provides some pieces of the whole puzzle.
W=mc^2 is BS. Using magnetic field in the opposite direction is capable of completely destroy hydrogen. Yet, the energy produced doesn't agree with the equation. The REAL formulae of energy is W=(1/2)*L*I^2 and W=(1/2)*C*E^2 The natural inductance and capacitance of free space, or rather, the *Aether* itself.
@TheAnax 11 Light moves with the same velocity as earth for god's sake. Static aether doesn't even change the direction of light. Not to mention they think of aether "moves". How stupid. The device they are using is moving at the same direction as light. Light is NOT limited by the medium it propagates in. It still has inertia! For example, it moves in a direction in x-axis, then a mirror reflect it to y-axis. It wouldn't magically slow down or speed up because aether is STATIC and does NOT magically inhibit light to the point it diverge from it's path. Those experimenters are pure trash of humanity. Now, science is pure trash without aether. And no. Light does not move with "space". Light propagates IN "space"/AETHER.
I finally understand at least the basics of Einstein's theory of relativity. My only problem was that I had to keep rewinding the video because of your accelerated speech. Thank you very much for the comprehensible vocabulary. Awesome video.
GREATEST VIDEO OF ALL TIME! I AM ABSOLUTELY MIND-BLOWN! I have always wanted to see something like this, and now I have. You have opened my mind to the possibility of AMAZING things. AND everyone knows it to be true. I now know the meaning of life. I now know everything. I now have purpose. And it's all thanks to you.
I’m so glad I found this channel and subscribed. I recommend various videos in physics and astronomy subreddits because I think this channel deserves more exposure to science enthusiasts. Have you considered collaborating with PBS Spacetime? Also, I’m extremely curious about the number of anti-relativity and anti-Einstein comments your videos must get on a constant basis. I can’t go to any physics video and not see at least one comment about someone talking about pseudoscience like the electric universe nonsense. Have you considered making a video addressing that nonsense and debunking it?
Thanks for your patronage! Regarding debunking videos - the scientist in me wants to make them to try to get "believers" to think more scientifically, but my impression is that it is a losing proposition. Why? Because the scientifically minded people do not need a silly concept to be debunked, and the true believers never seem to be convinced. A perfect example is my Bob Lazar video. I am open to doing this though if enough of my subscribers want it.
@3:17 This wave should move faster when it has the same direction with the earth, but shouldn't it move slower when bouncing off the mirror? This could make the two wave arrive always in phase. No?
The wave is always the same speed. This is what the special theory of relativity is all about. Light always moves at the same speed (in a vacuum), no matter what the frame of reference.
Yeah, I get that. I don't get how the experiment of michelson & morley showed that. I'm reading it right now in my university books. My question is, what if the wave while traveling to the right, let's say, gains 20% of speed and when it reflects and travels left loses 20% of speed (I think it should be the same percentage). Then the total gain of speed would be zero and it would be in phase with the wave that travels from up to down direction. So even if there is a change in speed we wouldn't notice it. I'm guessing the key here is the rotation of the device but still I can't find any details on this matter.
Don't want to put Einstein down or anything, but let's be honest here. Majority of little kids think about deep stuff and wonder how universe operates, they just don't work on their thought after they grown up. So it's not like Einstein was a special kid, he was just a kid that followed through. Great vid as always
Thank you. I appreciate that very much coming from a teacher! I taught as a grad student in college, and loved it. But I'm afraid I missed the calling and honor of full time teaching, choosing instead to pursue corporate management. But YT has given me a forum to pursue my inner passion.
Indeed you are correct. The Nobel committee usually does not award revolutionary ideas until those ideas are confirmed over decades in dozens of experiments.
It's incredible that physicists 200 years ago were using the same kind of experiments we use today in detecting gravitational waves. Using the phase of light.
Yeah, but Einstein never used miles per hour units. More like kilometers per hour. :) Also Energy is not equal to Mega x Capacity squared, because that phrase makes no sense, yet it was written all over the video. So... get those units and letters right next time. The channel will look more professional, and gain more viewers. ;) Cheers!
Very good video and presenter. He explains it so well. Always interesting to listen to people of great knowledge and also can present it in the best pedagogical way.
That's actually a great question! I would like to give two answers. The first answer is, if you somehow could travel at the speed of light, you would not need to drive anywhere because you would already be at your destination. Realistically though, in our universe, you can not travel at the speed of light if you have any mass. But if you travelled even 99.99999% the speed of light, your headlights would indeed work normally from your perspective. The remarkable thing is that an outside observer standing still would also measure that same speed "C" for that beam of light. How is this possible? This is the crux of special relativity. Time would slow down dramatically for you if you travelled at that speed, from the perspective of a stationary observer. Speed of light will always be the same for every frame of reference.
You don't really appreciate how much work goes into a video until you try making your own. The 3D animations must have taken a lot of work. I can't imagine.
Thank you for explaining quantum physics to those of us who haven't had the benefit of a hard science education. I am a constantly curious person & I rely on videos like yours to educate & inform myself. P.S. math is essential..to understanding our world.
I will make one on General relativity and include the math. GR derivation is much more complex than SR. I think you'll like it, if you love math! Stay tuned.
Tesla was a genius in his own right. Comparing scientist by who is smarter is pretty dumb. Einstein even said "Everyone is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid." Or at least, it's very often associated with Einstein.
I know light can red shift and blue shift but is there a limit were it stops being light/no more power (referring to red shift)I think blue shifting results in a black hole because as the bandwidth shrinks the power is still there but takes up less and less space resulting in a Kugelblitz eventually but at what is it's Schwarzschild radius power/bandwith. With red shift is there a limit other than the size of the universe?
Hi Chris ... That' a great question. The largest measured redshift is z=1089, the redshift of the CMB. That number will gradually increase as the universe is still expanding. However, that is not the highest possible redshift. That would occur at the event horizon of a black hole. As an object falls into the black hole, its emitted light will be more and more redshifted by the incredibly intense gravitational field near/at the event horizon. Theoretically it would continue to redshift until it fades from our possibility to measure it. The energy of the light will keep decreasing until the event horizon is breached. But, if you have viewed Arvin's other video on black holes and his explanation of what happens to his hypothetical astronaut "Adam", you will see where this is going. Adam will never be observed by anyone in the universe as having fallen past the event horizon. He is trapped there forever because time will slow to 0. But Adam won't notice it. From his point of view nothing has changed. He passes the event horizon uneventfully. So, what's up with that? Now you see what your question has led to, so I really suggest you check out Arvin's black hole video. Hope this helps!
@@ImaGoofyHead The expansion of space eventually exceeds the speed of light. Which strangely doesn't break any laws. The speed of light and the expansion of space are not connected.
Sir, thank you firstly for explaining these concepts in such simple language that even people with non-physics academic background can understand, or at least try to understand this stuff and be marveled by it. I have some questions that propped in my mind after seeing this video - What I understood is that for two people in different frames, on ground (Vijeta) and in a slow-moving train (Arvin), there is relative motion. If a third person person Virgina moved inside the train in opposite side of train (let's assume her speed > slow train's speed), and Arvin watched her move, then it's a simple thing : time = (Distance covered by Virgina)/(Virgina's speed). Whereas for Vijeta, it would be (Distance covered by Virginia's footsteps - Distance covered by train)/(Virgina's speed - train's speed). The time for both frames is same, whereas both distances (w.r.t Vijeta and Arvin) and both speeds (w.r.t Vijeta and Arvin) are different. But if Virgina is replaced by light and speed of light doesn't get subjected to Newtonian relativity, then the speeds (w.r.t. Vijeta & Arvin) remains same. Distances are different. So, time for Vijeta and Arvin must be different. - But how do we know for sure that if the train were moving at a very high speed nearing 300,000 km/s, then the Miss light walking in the train would not feel staggered a bit? That its speed won't be different w.r.t the two of us? - Secondly, it is well known that speed of light in various mediums like water, air and glass is different. We haven't gone close to Mercury, and can't exactly say about the medium near Mercury. What if it tempers with the speed of light and hence our calculations? - Thirdly, knowing that even the Sun and entire solar system also moves at such a high speed and is drawn by the forces outside our solar system making it move around centre of milky way, then the same forces also don't affect the adjacent and much smaller Mercury? - Fourthly, if Miss light now moved in same direction as train, then the displacement w.r.t Vijeta would be different, than if Miss light were moving in opposite direction of train. However, for Arvin, her distance stays the same. So, with respect to Vijeta, her displacement in both cases (i.e. her movement in both directions) is different. So, how could time (w.r.t Vijeta) be same in both cases? Time should be faster than Arvin's time in one case, and slower than Arvin's time in other. Waiting eagerly for your replies. Thank you.
Excellent. I got chills. This video is a review for me as well highlighting my many overlooked "loose-ends" when it comes to relativity. I hope this is someone's first doorway into relativity (Newtonian physics, and quantum physics for contrast / comparison). As I had so many years ago (Brief History & Chaos (James Gleick)). Thank you so much, great work !
Michelson and Morely were not testing the existence of the luminiferous aether, that was a given for almost all of physics at the time. They assumed there was a medium that allowed the propagation of light. They were testing how light behaved within this medium. The results were not what was expected. The motion of the Earth through the aether had no detectable effect on the speed o light.
Thanks great vid,.. so how faster the object goes the more mass and thus energy it has? Compaired to the "mass/energy in rest" That was something i didnt grasp from other videos.
You could also say that Maxwell took from others, but he built on them. That's how science works. I think the lack of boldness against the ether theory partly resulted from threats of careers, especially against the young scholars.
You have explained amazingly such a wonderful theory of physics in simple words and I has become a fan of your nice explanation. Thank you so much sir......
3:00 on words - Here there is an assumption that ether is moving and hence there is a difference between going up and down the direction of movement. What happens if the ether was stationary ? Like a ship moving in non turbulent ocean, weather go go up or down, there is no difference in speed?
@@ArvinAsh That's what I am saying. Take swimming in ocean as an example, if there is no water current, weather I swim in one direction or the opposite ... I will be swimming with same speed in both directions with same effort, meaning I will never be able to calculate the speed of the current or can I come to the conclusion as to weather I am swimming in ocean or not. ( One cannot make a distinction between non-existence of ocean(ether) v/s existence of stationary ocean(ether). Both means same.
@silverrahul Yes you are right. If there was a stationary ether (relative to the entire universe in the same way as light), Then the earth (and everything else) would be in relative motion to the ether. Therefore, the two beams would be out of phase because the relative motion (direction) of the light beams to the ether would be different. The experiment proved the exact opposite. Einstein took it up from there. That confirmed his conclusion that the speed-of-light must be constant everywhere in defiance of the law of relative-motion. Einstein concluded that the only other possibility was that time itself was actually a variable (t) relative to the speed-of-light (c). Hence v=s/t and we have relativity, time-dilation and spacetime all confirmed in one go...That's genius!
Well done..Its trendy to suggest general relativity CANNOT be right due to its conflicts with QM on gravity. Perhaps the predicted quantization of gravity is WRONG.. perhaps I'm just a relativity chauvinist..Excellent show.
I will be tackling General Relativity in a future video. Both QM and General relativity are correct. There is way too much evidence in favor of GR for it to be wrong.
A big A+ for your video ; clear and concise. 👍 I must say, however, that being a completely non-mathematician myself, some concepts would deserve a bit more of an explanation... 🙂
Arvin, I really do enjoy your content. I would love to see you do a crossover episode with "the science asylum" [youtube channel] & "Captain Disillusion" [youtube channel]
"Einstein's relativity work is a magnificent mathematical garb which fascinates, dazzles and makes people blind to the underlying errors. The theory is like a beggar clothed in purple whom ignorant people take for a king... its exponents are brilliant men but they are metaphysicists rather than scientists" NIKOLA TESLA
Tesla was a great engineer but a very bad physicist. And you conpiranoic anti semitic lunatics, please stop kidnapping Tesla. He has nothing to do with you. weirdos
I love ur videos channel content and everything but dude that miles?? Thats sucks..plzz never ever use miles plz use proper unite please speed of light is measured in meters per second easy 3*10^8 and not some rediculous number miles per second Noone uses this unit not even americans its miles per hour.i m pissed of.bcz..even though i know speed of light but many dont
That's the units that were used at the time that the speed of light was determined. But there's an easy fix, every time I say 186,000 miles per second, just think in your head 300,000 kilometers per second instead!
Physicist had assumed that time was a fixed constant. Mr. E took his thought observations and described what occurs in each frame of reference. To reconcile them, Mr. E determined that the passage of time was not constant. It was literally a leap of faith in the physics community. but it explained all that came before, literally, all the pieces of the puzzle fell into place. Mr. E's equation are very elegant, simple, beautiful, and art in their own right.
Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality. Nikola Tesla
I love science, so i love you sir, your videos answer to many of my questions in a very simpler way that otherwise i am unable to grasp, because i am an amateur
Einstein was asked something like what would the smartest man in the world think about that Einstein replied "I dont know ask Nicola Tesla he was the real genius
If he chased waves of sound, time is not affected. It is fact that Relativity, in order to work, CHANGES THE DATA FIRST. Transform equations make it work mathematically, and there has never been any attempt at making sense of the data before transforming it, because relative time is soooo FUN! Gamma Ray Bursts arrive in order of wavelength, but no one second guesses it. Send a pendulum into space, and you don't even have a clock anymore. Eddington's experiment was repeated in the '70s, and they had to confine data closer to the Sun to make it work. Now it is known that there is WAY more mass close to the Sun than previously thought. All of this is the goofiest blunder in human history, my opinion. I need the ether back.
A massless ether fits Michelson-Morley. Velocity is determined at production. The alternative is thinking that your changing motion changes every light wave in the universe. Come on! That's what math gives you -garbage in garbage out.
"And just like in life, history tends to favor the bold."

And by the way it’s been changed at least 15 times since it’s conception but you probably knew that right ??Your priests are telling you for the last 5 years that gravity isn’t a force.
George Musser 2019 “gravity isn’t a force but we can think of it as one”
Brian Cox 2015 “ gravity isn’t a force at all”
So I’ll just need that link for the scientific experiment that proves Einstein theory thanks.

It’s a watered-down vision for children. Relativity is the Truth and nothing can exist apart from the Truth! Amen!
Reality is darker! This video only talks about two or three phenomena consistent with relativity.
What about black mass? What about dark energy? What about the total incompatibility between the mathematical and therefore continuous relativistic view and the discontinuous view of quantum mechanics? What about the Sagnac experience? What about Professor Allais's statistics? And so on and so forth, and some of the best! Check out the list in the video: the collapse of physics th-cam.com/video/QA5b-moh4o0/w-d-xo.html
Superb, as usual. Here is Einstein himself, describing relativity: "Sit with a pretty girl for an hour, and it seems like a second. Put your hand on a hot stove for a second, and it seems like an hour. That's relativity."
Does it cancel out if I put my hand on a hot stove while sitting with a pretty girl?
Alexander Townsend No it cancels out when the Girl is hot
@@alexandertownsend3291 It would last forever, because you would chastise yourself why you behaved so stupidly in front of the pretty girl. Doesn't cancel out.
@@alexandertownsend3291 yeah but this is true only from the simp's frame of reference
I once dated a girl online, our first meeting lasted for about 1 hour but for me it was like 1 day,.. can someone explain this in theory of relativity..
You have a gift for explaining complex things in words we can all understand. Thank you!
he sure does. amazing.
Soo true.. brother soo true.. wish we had such teachers in our school times
Because hi really understudy the subiect
What if you explain it the simplest way but nobody still get it?
I will write here that Arvin Ash is wrong that Einstein was the first to put all this together. Many of the 'original' ideas presented by the 1905 Einstein paper was all established by Poincare in 1902 and years before, and stated more completely. Einstein refused to acknowledge Poincare until much later, in fact he has a history of being called a plagiarist due to his lack of crediting others and pretending the ideas were original. Physicists have not done their research on how relativity was constructed so they have perpetuated the Einstein myth, despute there being a completely valid reason why Einstein did not receive a nobel prize for special and general relativity.

You are genius, man !You simplify the most famous but less understood theory.
Least understood
Little understood
It's so wonderful looking at the velocity at the which his mind could think, that superb 'never give up' attitude just gives us so much to learn from.
I know you trying to sound sciency but using velocity in that concept is just malapropism his thoughts do not have a direction although you could say he thinks fast so really speed makes alot more sense
*Time* magazine named Albert Einstein the Man of the Century. How fitting.
I've watched many videos /documentaries on the subject and this is the best one I have ever seen.. the present/illustrations/examples are expertly assembled and intuitive.. congratulations on the excellent work.. explained simply indeed
I love how imaginative Einstein's way of coming into an idea was. He used to put himself into a scene and "feel" it
@Valeria Taylor I'd love a link to this assertion, please. I've read a lot of Einstein's work and haven't come across a statement such as this. Thanks in advance for any help you can give me,
Einstein was a plagarist.
Excellent, just what I was waiting for, will have to watch it a few more times which is understandable considering the subject. Thanks again.
Lucky you!! I'll have to watch it many more times!!!
this video was amazing. I showed it to my neighbors & they agreed, amazing. we are currently looking for a projector so we can show our entire village
Justa Fool Copypasta?? Seriously, where do u get this funny commentary.
Justa Fool Oh, so you were actually serious.
Then I will note for now that you seem to be confused.
I mean, I think a lot of people would notice your points and people have tried to debunk the theory, so try to rewatch.
If you are still confused, I am not able to help now, but maybe within 12 hours??
I will probably forget tho, so no promises.
Justa Fool Ok, so maybe I was overestimating on the time but here is my explanation.
Einstein says the equations are identical for all inertial frames of references, not the actual values of things.
Also, in regards to the observer field inconsistency, the field does not have a speed, because if it did, it would be relative and make the speed of light relative, which Maxwell did not calculate.
So just try to better understand this idea that has predicted many phenomena and given real experimental data. Even if the assumptions are slightly wrong, it is science and it is the best we got.
I think most people recognize almost all our equations are somewhat wrong but they are the best we got.
@@funkyflames7430 No, Im not satisfied with the rather lame and child like explanation that "its the best we have got".
If you think that einstein's is probably wrong, but we don't have a better story, well that's not sufficient reason to overturn classical physics which does give 100% accurate results. Also, SR is NT the best explanation by any measure! Its probably the crappiest explanation ever proposed! First of all, its an explanation or a solution for a problem that does not actually even exist! Its all make believe.
Where exactly does Einstein say that "the equations are identical for all inertial frames of references, not the actual values of things". ?
If the equations are the same, and you say the values are different, then the only conclusion must be that what you measured to get your values MUST not be what I was measuring. Try measuring the same things please, then you must always get the same values or results as i get, because we are both using the same equations... 2+2=4 here MUST still equate to 4 over there, because physics and math MUST remain the same in all frames. so no, if you get 2+2=5 over there, then you are not applying the same physics laws. If your answer of 5 IS REALLY TRUE, then this is PROOF that physics is NOT the same in all frames!
Make up your mind, pick a side and stay with it. Is physics the same in all frames or not?
"Also, in regards to the observer field inconsistency, the field does not have a speed, because if it did, it would be relative and make the speed of light relative, which Maxwell did not calculate."
How do you know that "the field" (what that is no body knows) is not moving?
This CANT be correct, because that would then comprise as the ABSOLUTE stationary frame of reference, and Einsteins expressly forbid any such thing.
So, no, you cant claim that "the field" is stationary, rather must be moving too, and its relative to everything else that's moving, or else Einsteins is wrong right here at this statement.
Maxwell never calculated a moving frame because he already assumed a stationary aether, which was his belief. Einstein contradicted Maxwell because he said that Maxwells equations are not invariant when motion is involved.
To make Maxwells equations invariant when motion is involved, Lorentz suggested that things shrink in the direction of motion, and that "explained" the M&M experiment's null result. Einstein just took it from there, but proposed that we can still have no aether, no absolute stationary frame of reference if we just say that Time also shrinks. What an idiot.
Maxwell in fact never suggested that light speed was a constant in all frames of reference, neither did M&M ever suggest this.
Maxwell said that light speed was in fact relative to the medium, and so did M&M. M&M could not find any measurable medium, and Maxwell never even bothered to look.
So EInstein's solution opposes Maxwell in one claim.
Maxwell said light is constant "relative the medium", (being the vacuum, or water, or air, or glass, or plastic) but Einstein said that light is constant "RELATIVE TO ANY OBSERVER".
This is clearly an irrational statement by a simple minded person, not a genius.
@@xiaoxiao-kg5np if you want to learn then you must leave behind your arrogant nature and your pre existing reasoning and go for the full details and then only start to make some analysis. Everyone finds it (SR) super confusing and somewhat unintuitive (not as much as QM though) but the postulates and the predictions of Special relativity has been tested so many times and proven in it's favour, it explains the nature of nature. What more do we want? If you find the theory not compelling then you might come up with one of your groundbreaking ideas, which we are all waiting for. Stay motivated sir!
Great video.Perfect understanding.Time did it in.Mass is not absolute.Now everything is clear.Never felt so delighted.Clear voice and excellent explanation.
As a math lover who doesn't remember much of it from college, this video is peerless. I have watched dozens of scientists discuss this subject on TH-cam and other sources; they covered the same ground as shown here and were superb for the most part. But this presentation was over-the-top, at least for me. The reason I say that is because I feel like I can explain this one concept to another person and actually have them understand it to a significant degree. I could never say that before. Cheers
I'm the type of person who leaves the club to go home and watch Arvin Ash when he uploads
haha...thanks for watching my friend. But why not watch it at the club?
At 3 to 5 ads per vid nowadays I wouldn't rush home too early.
You freak
He is great !!
Me too.
It really is mind blowing stuff, and I truly appreciate you, for simplifying this and other complicated subjects. Knowledge is power, and if we take it slowly, the things we learn from your videos will help us to understand the world we live in. I have subscribed and look forward to your next videos. Great work.
I am taking a high school physics class, and for our final project we have to research a modern physics subject. I am researching relativity, and your videos have been helping a lot. Thanks for the great content.
manurmad, The theory of relativity is a complete lie. It is based entirely on convoluted and deceptive mathematical models. Nikola Tesla’s statement about the modern methods of scientists like Einstein is revealing. ‘’today’s scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality.
Nikola Tesla was the most brilliant scientist and inventor of his time. So advanced were his discoveries that upon his death in 1943 his research papers were seized by the FBI and classified ‘’Top Secret’’ at the request of the U.S. War Department. One of Tesla’s most notable discoveries was alternating electrical current (AC) that is today used to power most homes and businesses. Tesla understood true science and knew a scientific scam when he saw one. In 1935, Tesla called Einstein’s theory of relativity ‘’a magnificent mathematical garb which fascinates, dazzles and makes people blind to the underlying errors. The theory is like a beggar clothed in purple whom ignorant people take for a king…, its exponents are brilliant men but they are metaphysicists rather than scientists.’’
plagiarization is intellectual theft. the unimpeachable record proves that Einstein was not a genius, but was simply a very clever con man, with powerful backers. Gwynne concludes that ''the truth about Einstein is that he was no more than a puppet.'' Gwynne presents compelling evidence that Einstein was selected to play the specific role of refuting the Michelson/Morley experiment (which proved that the earth was motionless) and reestablishing the rotating globular earth. and Time magazine actually put him on their cover and named him the Person of the Century.
The most I listen to this video, I learn more to teach my students. Thank you so much!
Good explanation with deep understanding !!! Deserve more views
I enjoy my vacations but I always miss not being able to watch my favourite TH-cam channels. I thought I had a grasp of relativity from my school days, but i was kidding myself, I didn't. Today I have a much better (but not complete) understanding. i'm working on the missing bits - thanks Arvin.
I wish I would have had more teachers at school who could explain things as well as you do Great vids
Thank you, you really do great videos. You are one of a few who can explain high level science in the way that ordinary people can learn something
i like the peoples whose are concise, brief and conclusive on the subject matter, ervin u are one of them ,i always wait ur videos and learn a lot
Sir,I have watched some of your videos.Your explanation is simple and any Physics enthusiastic person is able to understand. You are explaining, even Relatively in a possible and simple way.I am addicted to your videos.
Thanks and welcome
Maybe some scientists before him thought about solving the speed of light problem by suggesting "time must be relative", than abandon the idea because the idea that time flows slowly or faster for others look absurd.
This is why it is good to be openminded and think outside the box.
Technically what is "relative" are not space and time, but all of physics is relative, i.e. phenomena only depend on the distance between two objects and their motion relative to each other. They do not depend on something "absolute" third. This was already known to Galileo.
Just to say Arvin Ash's video's depict abstract scientific theories brilliantly. As in, no other channel I can find has 3D models of spacetime. They all use that trampoline curvature of spacetime but it does not give the general public the right idea of the full picture. They still don't know what spacetime is, or means, or its relevance within their own lives. Great job!
That was a very good foundation.
The idea that high speed astronauts come back younger, the twin paradox, sums up the mystery of relativity for most of us.
It would be brilliant if, in a future video, using a just a bit of maths you could do an animation showing visually why the time dilation must occur and where the time for the astronaut actually gets lost.
I haven't seen any really convincing ones and I know it would be very difficult because there are several different theories why it happens, Einstein linked it to acceleration, others didn't - big mystery.
An excellent piece of work to physicists. For a layman like me, a retired biology teacher, I try to explain this way to the general public.
The speed of light is known to be constant for different observers. An observer on the ground sees the speed of tennis ball by suming the velocity of train and that of the ball. The observer inside the train sees the speed of the same tennis ball by that tennis ball alone. But if on the train, a beam of ligjt is projecting, the ground observer would see the speed of light the same as the observer on the train because the light insist on the same veolocity to all observer. There is only one equation to calculate the speed of everything, length/time. Therefore in order to let the light keeping its constant speed, the length(and time, they change together though not in direct proportion) of the train travelled has to be flexibly experienced and spacetime dimension(in length travel) has to alter in that reality. This is an incredible conclusion that could stunt people around. As they immediately see the length of the 3D space are flexible or elastic, so connecting to the concept of spacetime being warping around. Of course, Einstein another achievement is figuring out the relative velocity of spacetime into pythrago's theorm of a right angle triangle for the train, the light and the ground observer. Layman could then understand the quantum related area because the emptiness is in fact something a 'fabric' there. Before when vacuum is emptiness, then there is nothing important to particles travel here and there because nothing in between. Since now there is a fabric of the universe which can be twisted, scientist had to find an explanation of how and why they come into existence, why they travel with different spead, even the sperpositioning, quantum entanglement, dark matter, dark energy, vacuum catastrophy, the black hole features, holograpgic universe, multiverse etc, finally pointing to a possible way of solving out the ultimate physics problem of the interaction and creation of our own universe! Of couse, the String theory, Field Interaction, knownledge from backhole provides some pieces of the whole puzzle.
No math? But that's my favorite part! :-D Seriously, thank you for your great videos!
you can't handle the math.
I spotted some equations in the video...was I seeing things?
W=mc^2 is BS. Using magnetic field in the opposite direction is capable of completely destroy hydrogen. Yet, the energy produced doesn't agree with the equation.
The REAL formulae of energy is W=(1/2)*L*I^2 and W=(1/2)*C*E^2
The natural inductance and capacitance of free space, or rather, the *Aether* itself.
@TheAnax 11 Light moves with the same velocity as earth for god's sake.
Static aether doesn't even change the direction of light. Not to mention they think of aether "moves". How stupid.
The device they are using is moving at the same direction as light. Light is NOT limited by the medium it propagates in. It still has inertia! For example, it moves in a direction in x-axis, then a mirror reflect it to y-axis. It wouldn't magically slow down or speed up because aether is STATIC and does NOT magically inhibit light to the point it diverge from it's path.
Those experimenters are pure trash of humanity.
Now, science is pure trash without aether.
And no. Light does not move with "space". Light propagates IN "space"/AETHER.
@Joe Duke Insane? Keep yourself indulged in pure math is the one that is really insane.
I finally understand at least the basics of Einstein's theory of relativity. My only problem was that I had to keep rewinding the video because of your accelerated speech. Thank you very much for the comprehensible vocabulary. Awesome video.
Wow, you have a very good way of explaining things in simple terms. Subbed, keep up the great videos!
GREATEST VIDEO OF ALL TIME! I AM ABSOLUTELY MIND-BLOWN! I have always wanted to see something like this, and now I have. You have opened my mind to the possibility of AMAZING things. AND everyone knows it to be true. I now know the meaning of life. I now know everything. I now have purpose. And it's all thanks to you.
Your videos are amazing Arvin. Thank you for making these concepts available to people without training in advanced math and physics.
I appreciate that!
I appreciate that you gave some credit to other physicists and mathematicians.
I’m so glad I found this channel and subscribed. I recommend various videos in physics and astronomy subreddits because I think this channel deserves more exposure to science enthusiasts. Have you considered collaborating with PBS Spacetime?
Also, I’m extremely curious about the number of anti-relativity and anti-Einstein comments your videos must get on a constant basis. I can’t go to any physics video and not see at least one comment about someone talking about pseudoscience like the electric universe nonsense. Have you considered making a video addressing that nonsense and debunking it?
Thanks for your patronage! Regarding debunking videos - the scientist in me wants to make them to try to get "believers" to think more scientifically, but my impression is that it is a losing proposition. Why? Because the scientifically minded people do not need a silly concept to be debunked, and the true believers never seem to be convinced. A perfect example is my Bob Lazar video. I am open to doing this though if enough of my subscribers want it.
What a great explanation. This should be compulsory viewing for anyone who's about to start special relativity
Love love love..... so glad I found this channel.... it's fantastic!
Awesome to find someone who can explain something complex and make it easy to understand. Thank you!!
Well thought out, good graphics, and well presented. I could of used this when teaching high school physics.
@3:17 This wave should move faster when it has the same direction with the earth, but shouldn't it move slower when bouncing off the mirror? This could make the two wave arrive always in phase. No?
The wave is always the same speed. This is what the special theory of relativity is all about. Light always moves at the same speed (in a vacuum), no matter what the frame of reference.
Yeah, I get that. I don't get how the experiment of michelson & morley showed that. I'm reading it right now in my university books. My question is, what if the wave while traveling to the right, let's say, gains 20% of speed and when it reflects and travels left loses 20% of speed (I think it should be the same percentage). Then the total gain of speed would be zero and it would be in phase with the wave that travels from up to down direction. So even if there is a change in speed we wouldn't notice it. I'm guessing the key here is the rotation of the device but still I can't find any details on this matter.
No, thank YOU Arvin! For such an easy representation.
Don't want to put Einstein down or anything, but let's be honest here. Majority of little kids think about deep stuff and wonder how universe operates, they just don't work on their thought after they grown up. So it's not like Einstein was a special kid, he was just a kid that followed through. Great vid as always
And I think he continued to maintain a child-like curiosity well into adulthood.
Great video, as usual. I'll watch it again, paper and a pen in hand, take notes and read MY notes, then I'll surely understand the whole thing. Lol.
I don't your current profession but as a teacher I really hope you are one of us. You are excellent !!!!
Thank you. I appreciate that very much coming from a teacher! I taught as a grad student in college, and loved it. But I'm afraid I missed the calling and honor of full time teaching, choosing instead to pursue corporate management. But YT has given me a forum to pursue my inner passion.
Fun fact: Einstein never got a nobel prize for the relativity theories.
He got one for the photoelectric effect.
Indeed you are correct. The Nobel committee usually does not award revolutionary ideas until those ideas are confirmed over decades in dozens of experiments.
Yes.. but why the huge space? Lol
Oh.. I get it. lol funny
Einstein even took Planck's idea for photoelectric effect
Probably they just didnt understand him because it was theoretical, so instead of that they gave him a Nobels prize on something that is observable
Holy crap it’s clicking. I never understood how time could be different but it’s all making sense. This is like blowing my mind
You really make it physics interesting for us thank you so much!
It's incredible that physicists 200 years ago were using the same kind of experiments we use today in detecting gravitational waves. Using the phase of light.
he explained this so well that it seems simple
It seems like the speed of light is more like a sample-rate (of the observer), as if we are chips with an internal clock rate.
Yeah, but Einstein never used miles per hour units. More like kilometers per hour. :) Also Energy is not equal to Mega x Capacity squared, because that phrase makes no sense, yet it was written all over the video. So... get those units and letters right next time. The channel will look more professional, and gain more viewers. ;) Cheers!

If i was driving at the speed of light and I turned on the headlights... would they work?
LOL, good one. I've seen this question before, and the answer is: since you can't drive at the speed of light, the question has no meaning.
Mike Petersen Its actually a steven wright joke!🤣🤣
That's actually a great question! I would like to give two answers. The first answer is, if you somehow could travel at the speed of light, you would not need to drive anywhere because you would already be at your destination. Realistically though, in our universe, you can not travel at the speed of light if you have any mass. But if you travelled even 99.99999% the speed of light, your headlights would indeed work normally from your perspective. The remarkable thing is that an outside observer standing still would also measure that same speed "C" for that beam of light. How is this possible? This is the crux of special relativity. Time would slow down dramatically for you if you travelled at that speed, from the perspective of a stationary observer. Speed of light will always be the same for every frame of reference.
Arvin Ash Haha I will relay that information to steve wright!! hahaha!!🤣🤣🤣Love your videos!
Yes... is the answer. Just ask the peeps on Earth 2 in a galaxy way far away on the other side of the universe.
You don't really appreciate how much work goes into a video until you try making your own. The 3D animations must have taken a lot of work. I can't imagine.
You're right

I know light can red shift and blue shift but is there a limit were it stops being light/no more power (referring to red shift)I think blue shifting results in a black hole because as the bandwidth shrinks the power is still there but takes up less and less space resulting in a Kugelblitz eventually but at what is it's Schwarzschild radius power/bandwith. With red shift is there a limit other than the size of the universe?
Hi Chris ... That' a great question. The largest measured redshift is z=1089, the redshift of the CMB. That number will gradually increase as the universe is still expanding. However, that is not the highest possible redshift. That would occur at the event horizon of a black hole. As an object falls into the black hole, its emitted light will be more and more redshifted by the incredibly intense gravitational field near/at the event horizon. Theoretically it would continue to redshift until it fades from our possibility to measure it. The energy of the light will keep decreasing until the event horizon is breached. But, if you have viewed Arvin's other video on black holes and his explanation of what happens to his hypothetical astronaut "Adam", you will see where this is going. Adam will never be observed by anyone in the universe as having fallen past the event horizon. He is trapped there forever because time will slow to 0. But Adam won't notice it. From his point of view nothing has changed. He passes the event horizon uneventfully. So, what's up with that? Now you see what your question has led to, so I really suggest you check out Arvin's black hole video. Hope this helps!
@@ImaGoofyHead The expansion of space eventually exceeds the speed of light. Which strangely doesn't break any laws. The speed of light and the expansion of space are not connected.
@@FobbitMike awesome input and thanx for sharing I just went and checked out the video do you know if my blue shift hypothesis is correct
@@christianheichel Yes, you are correct in your blue shift comment. Way to go!
@@ImaGoofyHead I fully understand the concept, I'm still not sure what your question is about there being a limit.
Sir, thank you firstly for explaining these concepts in such simple language that even people with non-physics academic background can understand, or at least try to understand this stuff and be marveled by it. I have some questions that propped in my mind after seeing this video -
What I understood is that for two people in different frames, on ground (Vijeta) and in a slow-moving train (Arvin), there is relative motion. If a third person person Virgina moved inside the train in opposite side of train (let's assume her speed > slow train's speed), and Arvin watched her move, then it's a simple thing : time = (Distance covered by Virgina)/(Virgina's speed). Whereas for Vijeta, it would be (Distance covered by Virginia's footsteps - Distance covered by train)/(Virgina's speed - train's speed). The time for both frames is same, whereas both distances (w.r.t Vijeta and Arvin) and both speeds (w.r.t Vijeta and Arvin) are different. But if Virgina is replaced by light and speed of light doesn't get subjected to Newtonian relativity, then the speeds (w.r.t. Vijeta & Arvin) remains same. Distances are different. So, time for Vijeta and Arvin must be different.
- But how do we know for sure that if the train were moving at a very high speed nearing 300,000 km/s, then the Miss light walking in the train would not feel staggered a bit? That its speed won't be different w.r.t the two of us?
- Secondly, it is well known that speed of light in various mediums like water, air and glass is different. We haven't gone close to Mercury, and can't exactly say about the medium near Mercury. What if it tempers with the speed of light and hence our calculations?
- Thirdly, knowing that even the Sun and entire solar system also moves at such a high speed and is drawn by the forces outside our solar system making it move around centre of milky way, then the same forces also don't affect the adjacent and much smaller Mercury?
- Fourthly, if Miss light now moved in same direction as train, then the displacement w.r.t Vijeta would be different, than if Miss light were moving in opposite direction of train. However, for Arvin, her distance stays the same. So, with respect to Vijeta, her displacement in both cases (i.e. her movement in both directions) is different. So, how could time (w.r.t Vijeta) be same in both cases? Time should be faster than Arvin's time in one case, and slower than Arvin's time in other.
Waiting eagerly for your replies. Thank you.
It's funny how the two gravitational wave observatories resemble the Michelson - Morley Experiment.
Thank you for excellent clear explanation of complex physical concepts. You are a Professor many will watch your video. Thank you.
Excellent. I got chills.
This video is a review for me as well highlighting my many
overlooked "loose-ends" when it comes to relativity.
I hope this is someone's first doorway into relativity (Newtonian physics,
and quantum physics for contrast / comparison).
As I had so many years ago (Brief History & Chaos (James Gleick)).
Thank you so much, great work !
Michelson and Morely were not testing the existence of the luminiferous aether, that was a given for almost all of physics at the time. They assumed there was a medium that allowed the propagation of light. They were testing how light behaved within this medium. The results were not what was expected. The motion of the Earth through the aether had no detectable effect on the speed o light.
Thanks great vid,.. so how faster the object goes the more mass and thus energy it has? Compaired to the "mass/energy in rest" That was something i didnt grasp from other videos.
Also, it dumps into space at least 100, 00000000...........01 % energy in the oposite direction .
You could also say that Maxwell took from others, but he built on them. That's how science works. I think the lack of boldness against the ether theory partly resulted from threats of careers, especially against the young scholars.
Yes, but who's the blond at 1:53?
haha...I was waiting for that question. She is a model. Don't know her name.
Priorities, this guy has them
Nice introduction! Waiting for next video
Thank you alot, great explanation
You have explained amazingly such a wonderful theory of physics in simple words and I has become a fan of your nice explanation. Thank you so much sir......
Can I just emphasize the fact that photoshopping young Einstein's face into the sketches made them kinda funny? lol
Have to admit. You are right! lol.
Explained very well without complicated math. Enjoyed the video.
This reminds me of John :p Fortis fortuna adiuvat :p fortune favors the bold
3:00 on words - Here there is an assumption that ether is moving and hence there is a difference between going up and down the direction of movement. What happens if the ether was stationary ? Like a ship moving in non turbulent ocean, weather go go up or down, there is no difference in speed?
The assumption is that ether is stationary on which everything else moves.
@@ArvinAsh That's what I am saying. Take swimming in ocean as an example, if there is no water current, weather I swim in one direction or the opposite ... I will be swimming with same speed in both directions with same effort, meaning I will never be able to calculate the speed of the current or can I come to the conclusion as to weather I am swimming in ocean or not. ( One cannot make a distinction between non-existence of ocean(ether) v/s existence of stationary ocean(ether). Both means same.
@silverrahul Yes you are right. If there was a stationary ether (relative to the entire universe in the same way as light), Then the earth (and everything else) would be in relative motion to the ether. Therefore, the two beams would be out of phase because the relative motion (direction) of the light beams to the ether would be different. The experiment proved the exact opposite. Einstein took it up from there. That confirmed his conclusion that the speed-of-light must be constant everywhere in defiance of the law of relative-motion. Einstein concluded that the only other possibility was that time itself was actually a variable (t) relative to the speed-of-light (c). Hence v=s/t and we have relativity, time-dilation and spacetime all confirmed in one go...That's genius!
Well done..Its trendy to suggest general relativity CANNOT be right due to its conflicts with QM on gravity. Perhaps the predicted quantization of gravity is WRONG.. perhaps I'm just a relativity chauvinist..Excellent show.
I will be tackling General Relativity in a future video. Both QM and General relativity are correct. There is way too much evidence in favor of GR for it to be wrong.
A big A+ for your video ; clear and concise. 👍
I must say, however, that being a completely non-mathematician myself, some concepts would deserve a bit more of an explanation... 🙂
Arvin, I really do enjoy your content. I would love to see you do a crossover episode with "the science asylum" [youtube channel] & "Captain Disillusion" [youtube channel]
Einstein should be an inspiration to every student in every country. Friend, your impact is only yours to make, no teacher or boss can hold you back!
Please use scientific standard units.
I am using the units that were used during the time of the scientists. It felt weird to me to be using 20th century SI units for this video.
Professor Einstein is the one I worship
Edit: I have never admired anyone so much thanx for this video
No job is 'lowly'.
I don't disagree. My description was perhaps dramatic.
Outstanding video Ash, and extremely well narrated.
"Einstein's relativity work is a magnificent mathematical garb which fascinates, dazzles and makes people blind to the underlying errors. The theory is like a beggar clothed in purple whom ignorant people take for a king... its exponents are brilliant men but they are metaphysicists rather than scientists"
NIKOLA TESLA
He stole many patents when working at the patent office Einstein was a thief
Tesla was a great engineer but a very bad physicist. And you conpiranoic anti semitic lunatics, please stop kidnapping Tesla. He has nothing to do with you. weirdos
All you said at the end are not obvious consequences for non geniouses, and deserve a proper explanation
I love ur videos channel content and everything but dude that miles?? Thats sucks..plzz never ever use miles plz use proper unite please speed of light is measured in meters per second easy 3*10^8 and not some rediculous number miles per second
Noone uses this unit not even americans its miles per hour.i m pissed of.bcz..even though i know speed of light but many dont
That's the units that were used at the time that the speed of light was determined. But there's an easy fix, every time I say 186,000 miles per second, just think in your head 300,000 kilometers per second instead!
Physicist had assumed that time was a fixed constant. Mr. E took his thought observations and described what occurs in each frame of reference. To reconcile them, Mr. E determined that the passage of time was not constant. It was literally a leap of faith in the physics community. but it explained all that came before, literally, all the pieces of the puzzle fell into place. Mr. E's equation are very elegant, simple, beautiful, and art in their own right.
Einstein was clever but even he said Tesla was the genius
no, no, none of that tesla malarkey in here, just stick to the virtual particles and magical fields and "dark" stuff...
@@ImYourProblem If there wasn't Tesla, you'd probably be the one in the dark.
ha, i was just being sarcastic.. Tesla is the man.
@@ImYourProblem foot in mouth
Einstein was just being sarcastic
One of the best explanations I've experienced. Thank you.
Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality. Nikola Tesla
@polka,
How exactly? Sabine Hossenfelder's a modern physicist who says something like that today.
I love science, so i love you sir, your videos answer to many of my questions in a very simpler way that otherwise i am unable to grasp, because i am an amateur
Einstein was asked something like what would the smartest man in the world think about that Einstein replied "I dont know ask Nicola Tesla he was the real genius
If he chased waves of sound, time is not affected. It is fact that Relativity, in order to work, CHANGES THE DATA FIRST. Transform equations make it work mathematically, and there has never been any attempt at making sense of the data before transforming it, because relative time is soooo FUN! Gamma Ray Bursts arrive in order of wavelength, but no one second guesses it. Send a pendulum into space, and you don't even have a clock anymore. Eddington's experiment was repeated in the '70s, and they had to confine data closer to the Sun to make it work. Now it is known that there is WAY more mass close to the Sun than previously thought. All of this is the goofiest blunder in human history, my opinion. I need the ether back.
A massless ether fits Michelson-Morley. Velocity is determined at production. The alternative is thinking that your changing motion changes every light wave in the universe. Come on! That's what math gives you -garbage in garbage out.
