When you spit facts, you can't just go full rhetorical, meaning as an educational presenter spitting facts you'll have to use body language for the tonal communication.
Not that it matters one way or the other, but are you a gay man by chance? I can't picture a woman using the phrase "wide, athletic stance," because it's something a PE coach (or gay man) would say to describe another man's pose. But you're totally right in that observation - and now I can't not notice how wide his stance is. He looks like he's getting ready to drop a duke in a port-o-pottie.
Whats Up If i recall correctly from my recollection of useless knowledge. When talking about the act of smelling, like a fart, were talking about the nerves in our nose is picking up particles attached to air molecules. In other words, we're smelling the air, which is not massless and travels at the speed of sound at sea level. If something requires a medium to reach you (ie smell and sound), then you already know it can't travel at light speed. And air molecules (doesn't travel in a straight line) bounces around other molecules before the scent travels to your nose, which is why there's a time delay between gas leaving underwear and you smelling a$$. Someone please correct me if I remember / described anything wrong.
This video is unique because it addresses an unspoken detail that has brought about a lot of confusion: speed of light and speed limit are often used interchangeably but in reality are separate concepts
I'm loving these tutorials. I can almost get my head around some of the key concepts. I feel really smart for about a week and then the details start becoming vague and I'm back to being a bit thick. Great stuff mate!
@@idontwantahandlethough THE MATHEMATICAL AND PHYSICAL PROOF THAT E=MC2 IS DIMENSIONALLY CONSISTENT WITH ONE AND WHAT IS A TWO DIMENSIONAL SURFACE OR SPACE ON BALANCE, THEREBY PROVING THAT ELECTROMAGNETISM/ENERGY IS CLEARLY AND NECESSARILY PROVEN TO BE GRAVITY (ON/IN BALANCE): This also clearly proves ON balance that E=mc2 is directly taken from F=ma. Magnificent. Gravity is a property of SPACE ON BALANCE. It involves adherence or cohesion. So, BALANCED inertia/INERTIAL RESISTANCE is fundamental ON BALANCE. Accordingly, ON BALANCE, TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE. Consider what is the man who IS standing on what is THE EARTH/ground (ON BALANCE). What is the blue sky ON BALANCE? This IS the blue EARTH AS this is expressed on balance WITH (or equivalently by) what is the eye. The translucent AND blue sky is consistent with what is BALANCED BODILY/VISUAL (AND electromagnetic/gravitational) EXPERIENCE ON BALANCE, as touch AND feeling BLEND; as ELECTROMAGNETISM/energy is CLEARLY (AND necessarily) proven to be gravity (ON/IN BALANCE). GREAT. The stars AND PLANETS are POINTS in the night sky ON BALANCE, AND consider what is the speed of light (c) ON BALANCE !! Consider TIME (AND time dilation) ON BALANCE. E=mc2 IS F=ma ON BALANCE, AS the rotation of WHAT IS THE MOON matches it's revolution; as ELECTROMAGNETISM/energy is CLEARLY (AND necessarily) proven to be gravity (ON/IN BALANCE). The tides are CLEARLY and necessarily proven to be electroMAGNETIC/gravitational ON BALANCE. I have also CLEARLY explained (ON BALANCE) why THE PLANETS move away very, very, very, very slightly in relation to WHAT IS THE SUN !! I have explained why WHAT IS THE EYE beholds what is then (ON BALANCE) WHAT IS THE BLUE EARTH. Notice the associated black “space” AND DOME regarding what is the eye. Again, the stars AND PLANETS are POINTS in the night sky ON BALANCE. ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE). Very carefully consider what is THE SUN ON BALANCE !! E=mc2 IS F=ma. Again, I have proven AND explained why the rotation of WHAT IS THE MOON matches it's revolution. Gravity cannot be shielded (or blocked) ON BALANCE. What is quantum gravity is CLEARLY fundamental ON BALANCE. Gravity is CLEARLY fundamental ON BALANCE. BALANCED inertia/INERTIAL RESISTANCE is fundamental ON BALANCE. Define “mass". You cannot. BALANCED inertia/INERTIAL RESISTANCE is fundamental. E=mc2 is taken directly from F=ma. CLEARLY, gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites (ON BALANCE); as the stars AND PLANETS are POINTS in the night sky !! Consider TIME (AND time dilation) ON BALANCE. GREAT. You have to CLEARLY AND fully understand what E=mc2 means and represents ON BALANCE. We want to understand the dimensions in a seamless (or balanced) fashion in relation to gravity AND ELECTROMAGNETISM/energy (including what is E=mc2). Consider one AND three dimensional SPACE ON BALANCE. Consider what is the fourth dimension ON BALANCE. NOW, consider all of the following. Consider what is E=mc2. CLEARLY, you have to understand what is a TWO dimensional surface OR SPACE ON BALANCE. c squared CLEARLY represents BALANCED acceleration in conjunction WITH what is NECESSARILY a dimension of SPACE ON BALANCE. The stars AND PLANETS are POINTS in the night sky ON BALANCE, AND consider what is the speed of light (c) ON BALANCE. This CLEARLY AND NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual ON/IN BALANCE. Carefully consider what is THE EYE ON BALANCE. Great. Consider what is gravity AND E=mc2 ON BALANCE. TIME dilation ULTIMATELY proves (ON BALANCE) that ELECTROMAGNETISM/energy is gravity, AS E=MC2 is CLEARLY F=ma ON BALANCE. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 is CLEARLY F=ma ON BALANCE; AS the stars AND PLANETS are POINTS in the night sky. Accordingly, ON BALANCE, the rotation of WHAT IS THE MOON matches it's revolution. TIME is NECESSARILY possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 is CLEARLY F=ma ON BALANCE. The stars AND PLANETS are POINTS in the night sky. Accordingly, ON BALANCE, it makes perfect sense that THE PLANETS (including WHAT IS THE EARTH) will move away very, very, very slightly in relation to what is THE SUN !!! ELECTROMAGNETISM/energy is gravity, AS E=MC2 is CLEARLY F=ma ON BALANCE. Inertia/INERTIAL RESISTANCE is proportional to (or BALANCED with/as) GRAVITATIONAL force/ENERGY, as this balances gravity AND inertia; AS E=MC2 is CLEARLY F=ma ON BALANCE; AS ELECTROMAGNETISM/energy is gravity.

I know right? With the beard, he looks like a professor. Without, he looks like a grad student. I guess he suffers from Will Riker Syndrome, aka Baby Face Disease.
I suppose he is instead uber-famous like Eddie Raven or perhaps Eddie Rabbit? How about Edie for obscure? Enya? I know, the New Bohemians. Rick Astley was a Jordache wearing pre-George Michael wannabe with only one hit during the worst era ever to be a charting musician. A veritable nobody on the 'billboard' of history. In other words: yes, obscure...
The way that I always described c was "the speed at which a massless wave propagates in empty space." Light happens to be one of these massless waves but there are many others.
This perspective is interesting to me, because I work in particle physics and would say the same thing, except I'd say massless particle instead of wave because that's the way I end up thinking about light and gravity more often.
This is especially good because it’s a very intuitive way to understand why gravity travels at light speed. Gravity is also a massless wave- one of the very fabric of space-time itself, and thus being massless (space itself is just an empty vacuum with matter taking up some space) propagates at “light speed”
Hehehe... You spelled 'bare' wrong. :-) After all, it was as fleety as a streak of light... do not peer between the legs of that wide stance... one may miss his meaning...
Wow, you captured the reasoning behind the Lorentz Transformation so beautifully without doing any math! For anyone who has a good understanding of classical Mechanics, I'd also recommend Leonard Susskind's lectures on this.
If you want to keep your sanity, I suggest forgetting Leonard Susskind and going with Lynyrd Skynyrd. Quantum is getting stranger and stranger, and the math is starting to reflect this. It's almost as if quantum theory, or even the universe itself, perhaps, is reacting to the math, which is reacting to quantum theory. The universe is behaving like it isn't real, like it's an illusion, that changes according to what we say it should be.
It is! And you can show actually show the neat result he mentions with high school tools (derivatives, affine functions, a bit of physics), so it's not quite as out of reach as some people might think
@@ChaineYTXF Agreed. I first learnt Newtonian physics at school, with v=u+at and equations like that and it all made sense step by step. Im always on the lookout for a description just as simple for relativity. And this video is nearly there for me. It seems the best way to approach it is forget about light, forget about weird spooky shrinking spaceships, just go back to how space and time works. Im going to watch this a few more times and try working through the maths. The aim being showing Lorentz transformations with meaningful diagrams. Something my brain can hang on to all the way through.
speed of light is made up bs , for example lets say thers no living being that have eyes that can look the light , lets say when u turn on a light the light doesnt move , all the area that is being iluminated by the light is the area where the light source has enough power to reach the more powerful the light the larger the area it will iluminate and be seen in case thers eyes to look at that light , this is why u point a laser in one direction lets say u point it forward but someone who is in back direction will still see the light
phuturephunk but seriously though the derivation of lorentz transformation doesn't really require higher order maths once you know how 2 reference frame communicates
It's a bit depressing when people have to downplay content containing algebra. It's like everybody what taught that everybody hates it, it's like algebra is a punchline
If you'd paid attention in your secondary school science classes you would be able to understand the concepts, maybe not the math. Lose the video games, close your social media apps and start reading.
It's weird, but learning that there was a speed of causality is very comforting to me... The concept of things being limited to the speed of light was like an itch in the back of my mind
Yes, but empty space is not limited by the speed of light and can expand faster, that is why far away cosmic objects are moving away from us faster than the speed of light (because the expanding space in between). The light coming from those objects will never reach us..
how about u stop being dumb believe man made bs , thankfull thers still ppl like me who have common sense that know that light is not actually moving its made up idea , for example a candle 🕯has light in it and its not traveling to ur eyes when u see it , if u see a light it means u are inside of the area that the light is being emitted , why do yall think that the light is traveling to our eyes 🤣
@@joostdriesens3984 the only way "speed of light " could make sense is if u holding a light a something like a flashlight and u move it while the light is on , in that situation then u could say the light is moving but even in that situation the light is not actually moving
I came to this realization from thinking about how a video game is made. The programmer is God and maybe aka the Universe. The light you see is the End Result of the Video game. But the hardware and code behind the scenes must make that light must move faster than light or before the light moves. In fact, they have measured some sort of weird delay between what actually happens and what you see. Almost like when your screen refresh on your monitor to catch up with the computer calculations... maybe that is like quantum information signals can finalize where the waves intersect to create atoms.
@@joostdriesens3984 Something that really blows me away is the concept of overlapping light cones. Like you can see 1 light year further to your "right" than someone 1 light year to your "left". That means that things in that light year of space exist casually to you, but not to that person 1 light year outside of that light cone. Screw uncertainty, it is certain that points in space can exist and not exist at the same time depending on your point of reference.
Theoretical Physics - Exam Question 1: --Imagine Curious George is riding upside down on a skateboard hovering inches above My Little Pony. Also, Curious George is electromagnetic. Calculate the speed of light.
"How shall we explain causality, the speed of light, and space-time in easy-to-understand terms?" "Let's explain it in terms of a rollerskating pony with a skateboarding monkey on its back... and the monkey is ELECTRIC...!"
I understood every word of what he said. And TRUST ME, THIS IS, AS EASY AS IT GETS !! I mean you're trying to understand how the blood and bones of the UNIVERSE works !! Trying to tear it's flesh and skin apart !! (Even though just conceptually not really, I know) Frankly, it'd be tough to do a better job than this in simplifying/trivializing this concept for the masses !!
Society of Physics Students -- UCLA has now given the following writing the thumbs up on their page: THE TRUE AND THE ULTIMATE UNIFICATION OF PHYSICS/PHYSICAL EXPERIENCE IS NOW MATHEMATICALLY PROVEN: Gravity/acceleration involves BALANCED inertia/INERTIAL resistance, AS E=mc2 IS F=ma. ACCORDINGLY, the rotation of WHAT IS THE MOON matches it's revolution. This explains why objects fall at the SAME RATE (neglecting air resistance, of course), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY. "Mass"/ENERGY IS GRAVITY. E=mc2 IS F=ma. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity AND ELECTROMAGNETISM/ENERGY are linked AND BALANCED opposites, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. INDEED, time DILATION proves that electromagnetism/ENERGY IS GRAVITY; AS E=mc2 is DIRECTLY and fundamentally derived from F=ma. "Mass"/ENERGY IS GRAVITY. Ultimately and truly, time is NECESSARILY possible/potential AND actual IN BALANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 IS F=ma. This CLEARLY and truly explains c4 from Einstein's equations. THE FOURTH DIMENSION IS THUS CLEAR, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. BALANCE and completeness go hand in hand. I have mathematically unified physics/physical experience. The stars AND PLANETS are POINTS in the night sky. A PHOTON may be placed at the center of what is THE SUN (as A POINT, of course), AS the reduction of SPACE is offset by (or BALANCED with) the speed of light; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. It all CLEARLY makes perfect sense. E=mc2 IS F=ma. Time DILATION proves that electromagnetism/ENERGY IS GRAVITY, AS E=mc2 IS F=ma. GREAT !!! IT IS CLEARLY PROVEN. INSTANTANEITY is thus CLEARLY FUNDAMENTAL to what is the FULL and proper understanding of physics/physical experience. (Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black.) By Frank DiMeglio
@@frankdimeglio8216 not sure i understood all that, from what i understand, 'gravity' is not a force but the curvature of spacetime warped by mass, not necessarily caused by electromagentism, but either you are a misunderstood genius, or offbase, thanks
This episode was as accurate PBS news or documentaries have become since 2016. making their name stands for pure something or other ... WHY should everyone's CLOCKS reconcile off the speed of light ..? whether they're travelling 99.99% the speed of light -- and shoot a laser in front of them (or turn on their headlights) ... only for their clocks to slow concomitant to their relativistic speed, such that they perceive the speed of that light to simply be "C" despite their speed also being indistinguishable from C ..? WHAT OTHER than light is demanding this reconciliation. This claim is PURE POOP. (Much like the 10 hit pieces they did on orange man. Pure dookey of a MALE-COW ... which are words this channel is just TOO insecure to endure ... as if they knew they were true!? lol. Talk about reconciliation!
@@trumanhw Time dilation is not something PBS made up. Ever heard of Einstein and his theory of relativity? That theory has been proven accurate again and again through experiments. If you want a real life everyday example, read about satellites in orbit around Earth where time dilation occurs exactly as predicted by that theory and therefore we can compensate for it.

Even though I have a bachelor's degree in mathematics, and a much better understanding of physics than the average college graduate, I'm going to have to watch this a dozen more times to understand it fully. But by the same token (my education and what I've learned from extracurricular study), I can confidently say that this video really does explain everything promised, and more--in an incredibly concise way. Fantastic job!
Mathematics is not physics. It's not even close. Not that a bachelor in mathematics is worth anything. Even my high school math teachers all had a masters degree. ;-)
@@kbanghart A bachelor's degree is worthless, whether it's in math or hair styling. What employers are looking for in the job market is people with experience. That requires four to ten years of study and active work in the field, at the very least.
Another spectacular episode. This is quickly becoming my favorite channel on youtube. I was (and of course still am) sad to see Gabe leave, but it is beyond obvious we're in good hands with Matt. MY love for this show has not waned one bit, Matt is knocking it out of the park each time, which honestly I did not think anyone who is not Gabe could do this well with this format. I was wrong, and I am very happy for it. The community is also still pretty much the best damn community on youtube. Especially with boss people like Gareth and mage davee, and a ton of other crazy smart and helpful people answering all the questions that are given to to them. Add to that the continued and frequent contributions from people working on the show itself, and this is quickly becoming a community you can't help but be proud of, and make you want to participate in.
I love seeing these older videos after seeing new videos challenging the previous thoughts and theories. So happy they are continuing to dig deeper into the fundamentals of what makes our reality. Continuing to ask how and why and finding better answers.
I really enjoyed this. I think the thing that applies to my job the most is understanding that while the speed of an electron or other charged particle is fixed and slow, the speed of the magnetic waves propagation is also fixed, but at the maximum speed possible.
@Geo Thomas The universe doesn't make sense because every observer measures the universe differently. Somebody in motion will have a velocity and his time would be slower than your time if you are at rest. So technically your past is that person's present. Hence there's no reference frame to describe reality. We perceive reality through reference frames. The only thing that you and that guy in motion can agree upon is space time interval or space time. That's the only thing which every single observer can agree upon and that is the only reality. The universe the way you perceive it is only real to you and you only. But only space time is real for everyone
The big bang tells us that you can not standstill completely in the universe , the expansion triggered by that moment of the big bang in getting faster and faster.
Random Guy - No, Vu is correct in a literal sense. We are always in motion because the Earth is in motion and we are on it, the Earth is spinning at around 1000mph in addition to that movement, the galaxy is moving, and everything else in space is moving along with expanding empty space. The consequence is the inability to truly be still and a Universe without a center point.
Yeah, he can't be a real physicist. With that lack of a paunch, the reason he's wearing that t shirt can only be to show off his physique. I know of no real physicists who are into that sort of thing.
We need a finite speed limit for our *experience* of reality, which is also what space-time is fundamentally defined according to. There are unanswered questions about the nature of that experience though, and it's worth considering that on some deeper level, everything does exist as a hole, cohesive, "here and now". Both could simultaneously be true.

I'm not sure how they could have improved the clarity, if that's what you mean. But they did get a bit hand-wavey at a couple points, so maybe you mean they've gotten better about going into relevant details while still keeping the videos digestible.

At the speed of light, time stops. Light is everywhere all at once. The universe is a web of electromagnetic energy. It's our perception that defines space time and velocity.
This video is a huge jump for people not accustomed to the math he is talking about. Mathematics is a series of stepping stones after all, can't jump multiple steps at a time. There's really no way around it other than study up and maybe one day this video will be crystal clear.
Simply think that WE are the weirdos, travelling at speed different from the default speed of the universe, only because we are always slowed down by the Higgs field. Pure matter in the form of energy doesn't move at those shameful speeds ! 😂
Every century we have new geniuses that change the way we think about the universe as a whole. I'm very anxious to know which one we will live to see, in this century.
Thank you!! I have always wondered about why the speed of light was used!! Seeemed like a random high number but explaining it as the fastest way to propagate causality it makes sense!!
i love the way space time has gone more serious with its explanations. it breaks my brain every week. but will we see any more "fun" videos that try to explain the physics of fictional worlds like games or movies? though i like the serious ones more to be fair.
By necessity he's just skimming the surface of the underlying mathematics and physics but he served up as clear an explanation of why "The speed of light is not about light" as one can do given just under 13 minutes.
Clear as mud more like. This video is a waste of time. Nobody learnt anything. Nobody here can say why 'The speed of light is not about light'. It is possible in 13 minutes but the YT videos don't exist yet
A lot of mind-blowing revelations from this video, but one that caught me off guard was when he mentions that mass is an impediment to motion. Well yes, obviously it is. But then you think about it even deeper and realize that that's what mass IS, that's what energy IS, is an impediment or slowing down of transferring of information within the fabric of reality, which is spacetime.
So in other words...humans aren't meant to go anywhere...since we have mass. And as we all know, as speeds approach C, mass approaches infinity. Light can go this fast because it has no mass.
I enjoy Matt's videos so much! I'm usually just "hanging on" as he bobs and weaves through the math sometimes, but I always learn something fun and important!

@@alwaysdisputin9930 from what I can tell, it doesn't go into why causality has a limit, just that it does and why it's important, and why that means light moves at that speed.
@@alwaysdisputin9930 Yeah. I wish they would have gone deeper into actually explaining _why_ that is the case; it's pretty interesting stuff and this would have been a great video to explain it. I bet there's another video on this channel somewhere where he goes into it in more depth, but it would have fit well into this video and it's confusing enough that it wouldn't be the worst thing in the world to repeat it in multiple videos!
I came to the same point, when I thought about light. As I tried to search information about light, I found this video. I think light has a speed of 0 of the universe.
Why does it matter WHEN you get a random recommendation? TH-cam recommendations have always been random. I just dont get it. Why complain about something that you can freely ignore?
Were all sub atomic particles, doing our part without knowing to keep a greater "whole" going with a sense of individuality. Time cannot truly play a part in anything considering it is a common denominator created by man. I love how we revert back to old people who are dead and use old shit math to attempt to make sense of anything we experience. There is no universe and this isn't real. You will "die" its a perceivable common denominator and a system created. Solipsism is real. Your are the center of life. Look around and see that you truly can do anything. All you have to do is make a move and break free from the system you've been forced to believe in and stay original.

Question- some galaxies are so far away from us that even at the speed of light we could never get to them. If the speed of light is actually the speed limit of causality in the Universe rather than just a speed limit, then how could galaxies this far away possibly have any gravitational effect on us since we are moving apart faster that the speed of causality could reach us?
While today they are too far away for new information to reach us, the gravitational effect information of today left long ago when we were still reachable, it just took until now to reach us. While there is the gravitational effect of the past versions of those galaxies, there will never be such a gravitational effect from those galaxies as they actuallly are right now. Just like we see them now the way they were long ago, but will never see them the way they actually are right now.
in short they where all gettign their numbers wrong due to different hypotheses based on current numbers and assumptions . having observed light at a cetain speed does mean its the only speed, and then they base all their calculation on this constant that might be a fluctuating pulse . Imagine if the speed of light was 10 times faster at the start of the univers , that will make the universe 10 time younger than previous thought.
@Dirk Knight The video is pretty informative tbh. I dont know why you are making a fuzz about this statement....It was just supposed to make a person laugh. lol
I do not think that was a joke. He meant that we need to assume there is a law for it that we can uncover instead of chaos. And by chaos I mean random results.
@Dirk Knight Did you know that the sum of individual mass of proton and electron is more than the mass of hydrogen, which is made of proton and electron? It's like saying 1+1 > 2. Does that make sense? Not at first. But, scientists assume that the universe has to make sense, and that motivates them to search for a logical reason. There are more examples, like quantum tunneling. If you knew anything about modern physics, you wouldn't have said all the stuff you said here. You're actually suffering from Dunning-Kruger effect.
I cannot thank you more for making this video. I've had struggled for years with some questions about speed of light and relativity that I could not find answers to, that I could not quite understand, and they are all amazingly answered in this very video. Thank You!!!!!
On the one hand, this is the most beautiful & comprehensive explanation I've ever seen to answer the biggest quandary I've spent my entire adult life trying to wrap my head around: why does it seem that mass, energy, velocity, time, light, space, entropy, gravity, causality, kinetic energy, atoms and even the 4 fundamental forces... are all different angles looking at the same process? My grasp always ends up feeling half-assed. On the other hand - while all or most of these angles are entailed herein - it's still the age-old problem that each component causes you to think of how it relates to 50 other considerations... so when he explains 20 details to wrap your head around the one big picture, I find myself caught-up in all the implications of just one of those details. So instead of processing how all the 20 details relate to each other, I can only juggle 2 or 3 at a time with all their 50 sub-considerations each. Man... sometimes I wish I could just settle on being another jackass endlessly arguing about how "Liberals" or "Conservatives" are to blame for everything.
Durzo, look at it this way: If the laws of physics are true then they must be true everywhere, under all conditions of speed and gravity. This was perhaps Einstein's most fundamental understanding. Based on his predecessors' work he was able to show conclusively that the only way this can happen is if the speed of light (or causality) is constant. Assuming that, it all makes sense. But if you deny it then nothing makes sense. Remember that geniuses have exceptionally clear minds. In 1916 Einstein wrote a slim volume called "Relativity: The Special and the General Theory", subtitled "A Clear Explanation That Anyone Can Understand". He wasn't kidding; the clarity and simplicity of his thinking is astounding and illuminating and very understandable. A more contemporary example of a genius' point of view is Nobelist laureate and physicist Richard Feynman's "Surely You're Joking, Mr. Feynman." He tells how he cracked safes (during his work at the Manhattan Project!) for the fun of it and it's a marvel of the kind of basic logic that most of us say only afterward, "Yes! Of course!" Don't settle, Durzo! Keep exploring.
Paul M Actually just a few days ago, for the very-first time in my life, after 10 years of trying to wrap my head around all the implications of Relativity... it just suddenly came together, _fully_, during another hours-long session of over-clocking my frontal and parietal lobes. I wouldn't be surprised if all the considerations that go into a unified picture end up numbering in the hundreds... it was the most potent version of a "religious experience" I've ever had, but sure enough, once I got it I couldn't imagine how I was ever capable of _not_ getting it. I always knew I had all the pieces but just couldn't fit and hold them all together all at once - but let me tell _anyone_ else who's made it one of their ultimate life's ambitions to learn: despite the insane complexity of every possible consideration, once you *do* get it, you go back and run any one of those brain-strainer pieces through your mind-processor, and the software in your brain - now that it's calibrated right - just zips it through a well-oiled machine and instantly knows where the idea fits and how.
Harish adithya: No, the history is important. Those of us who dispute history are doomed to repeat it (perhaps not a direct quote, but it conveys my meaning: in that regard it is statisticly similar to the price of rice AND tea in China.
Nocturno: Sure it did, but rationally. "Everything" covers a lot of ground and the size of the ground it covers is increasing in harmony with The Law of Entropy in which "entropy is disorder". The Law states that the total amount of disorder in the universe is increasing at the expense of order. Substitute "CONfusion" for disorder and "Fusion" for order and what do you have? Well, my interpretation is that the amount of CONfusión is increasing at the expense if fusion (CON meaning against and fusion meaning the coming together of- such as in a thermoFUSION atomic bomb as opposed to the fission bomb). Does that make it less complicated to you? It did and does make it analogously easier/simpler for my little brain. Or, as my grandfather (who had only a high school education) told me, " The nore you know the more you realize how much more there is that you don't know".
The monkey and the pony are the reason why. Its a linear attempt to hint at the fact that 'we' don't know what speed we are traveling at. Nothing in the universe is linear. There are no straight lines in physics. The earth (monkey) is rotating around itself = surface velocity. The earth (monkey) is rotating around the sun (pony) = + oscillating surface velocity 1. The sun (pony) is rotating in the milky way = + oscillating surface velocity 2 The sun (pony) is rotating around the milky way = + oscillating surface velocity 3. The milky way might be rotating around another galaxy ... galaxies = + oscillating surface velocities n. Everything rotates around the centre of the universe. We don't know where the centre of the universe is ... therefore we have no idea at what nonlinear (oscillating) velocity we are traveling. We don't know where the famous location of the neutral 'observer' is ...the centre of the universe. All we can conclude is - if velocity/space/time are related - time itself can't be constant or linear. We basically know nothing. The 'Observer' however at the centre of the universe can call himself God, because by adjusting his position he can travel through time and space ... history and future at will.

This is the best modern series! Accessible, often hilarious, built for the "modern crowd" and most importantly accurate hard science. LOVE IT. Ok a question. In its pre Big Bang state, could C have been infinite? I have read and seen that during the inflationary period that spacetime grew at a rate faster than C, and as you have said here and in other videos that spacetime does not care about C. Is there a way to test this? Could we create localized variable spacetime densities? This question might tie into a video about "warp drive" speculation based on Alcubierre's work? Thanks again! You rock!
It is possible to check the speed of light!!! You need to put two split electrons within distance of 299,792,458 meters away from each other. They change straight away if you change one. You change one at the very same time you switch laser on and check on the other side where other electon is placed what is the time from electron change to receiving laser light. So deam simple.

I think of it the following way: Imagine you're in an unknown country and you don't know the laws, then you want tou know the maximum permitted velocity in a highway (analogous to space-tme) and everything you have to measure is a speedometer. Then you find out the max velocity is reached by a Ferrari and you name it "speed of Ferrari". But it is not a speed inherent to the car itself which only complies the maximum permitted velocity, instead is a property of the highway or the law Am I correct?

This video didn't state a single reason why the speed of causality = c. Nor did it give a single reason why massless objects have to move at c. It wasn't "explanatory" at all.

Not that it matters one way or the other, but are you a gay man by chance? I can't picture a woman using the phrase "wide, athletic stance," because it's something a PE coach (or gay man) would say to describe another man's pose.

good question, I wondered that myself.
Whats Up If i recall correctly from my recollection of useless knowledge. When talking about the act of smelling, like a fart, were talking about the nerves in our nose is picking up particles attached to air molecules. In other words, we're smelling the air, which is not massless and travels at the speed of sound at sea level. If something requires a medium to reach you (ie smell and sound), then you already know it can't travel at light speed. And air molecules (doesn't travel in a straight line) bounces around other molecules before the scent travels to your nose, which is why there's a time delay between gas leaving underwear and you smelling a$$.
Someone please correct me if I remember / described anything wrong.
This video is unique because it addresses an unspoken detail that has brought about a lot of confusion: speed of light and speed limit are often used interchangeably but in reality are separate concepts
YA.THE SPEED OF LIGHT,IS THE SPEED THAT LIGHT CAN GO.LIKE THE SPEED OF SOUND,IS NOT THE FASTEST THING ON EARTH.🙂🙂🙂🙂

@@idontwantahandlethough THE MATHEMATICAL AND PHYSICAL PROOF THAT E=MC2 IS DIMENSIONALLY CONSISTENT WITH ONE AND WHAT IS A TWO DIMENSIONAL SURFACE OR SPACE ON BALANCE, THEREBY PROVING THAT ELECTROMAGNETISM/ENERGY IS CLEARLY AND NECESSARILY PROVEN TO BE GRAVITY (ON/IN BALANCE):
This also clearly proves ON balance that E=mc2 is directly taken from F=ma. Magnificent.
Gravity is a property of SPACE ON BALANCE. It involves adherence or cohesion. So, BALANCED inertia/INERTIAL RESISTANCE is fundamental ON BALANCE. Accordingly, ON BALANCE, TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE. Consider what is the man who IS standing on what is THE EARTH/ground (ON BALANCE). What is the blue sky ON BALANCE? This IS the blue EARTH AS this is expressed on balance WITH (or equivalently by) what is the eye. The translucent AND blue sky is consistent with what is BALANCED BODILY/VISUAL (AND electromagnetic/gravitational) EXPERIENCE ON BALANCE, as touch AND feeling BLEND; as ELECTROMAGNETISM/energy is CLEARLY (AND necessarily) proven to be gravity (ON/IN BALANCE). GREAT. The stars AND PLANETS are POINTS in the night sky ON BALANCE, AND consider what is the speed of light (c) ON BALANCE !! Consider TIME (AND time dilation) ON BALANCE. E=mc2 IS F=ma ON BALANCE, AS the rotation of WHAT IS THE MOON matches it's revolution; as ELECTROMAGNETISM/energy is CLEARLY (AND necessarily) proven to be gravity (ON/IN BALANCE). The tides are CLEARLY and necessarily proven to be electroMAGNETIC/gravitational ON BALANCE. I have also CLEARLY explained (ON BALANCE) why THE PLANETS move away very, very, very, very slightly in relation to WHAT IS THE SUN !! I have explained why WHAT IS THE EYE beholds what is then (ON BALANCE) WHAT IS THE BLUE EARTH. Notice the associated black “space” AND DOME regarding what is the eye. Again, the stars AND PLANETS are POINTS in the night sky ON BALANCE. ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE). Very carefully consider what is THE SUN ON BALANCE !! E=mc2 IS F=ma. Again, I have proven AND explained why the rotation of WHAT IS THE MOON matches it's revolution.
Gravity cannot be shielded (or blocked) ON BALANCE. What is quantum gravity is CLEARLY fundamental ON BALANCE. Gravity is CLEARLY fundamental ON BALANCE. BALANCED inertia/INERTIAL RESISTANCE is fundamental ON BALANCE.
Define “mass". You cannot. BALANCED inertia/INERTIAL RESISTANCE is fundamental.
E=mc2 is taken directly from F=ma. CLEARLY, gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites (ON BALANCE); as the stars AND PLANETS are POINTS in the night sky !! Consider TIME (AND time dilation) ON BALANCE. GREAT.
You have to CLEARLY AND fully understand what E=mc2 means and represents ON BALANCE.
We want to understand the dimensions in a seamless (or balanced) fashion in relation to gravity AND ELECTROMAGNETISM/energy (including what is E=mc2). Consider one AND three dimensional SPACE ON BALANCE. Consider what is the fourth dimension ON BALANCE. NOW, consider all of the following.
Consider what is E=mc2. CLEARLY, you have to understand what is a TWO dimensional surface OR SPACE ON BALANCE. c squared CLEARLY represents BALANCED acceleration in conjunction WITH what is NECESSARILY a dimension of SPACE ON BALANCE. The stars AND PLANETS are POINTS in the night sky ON BALANCE, AND consider what is the speed of light (c) ON BALANCE. This CLEARLY AND NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual ON/IN BALANCE. Carefully consider what is THE EYE ON BALANCE. Great. Consider what is gravity AND E=mc2 ON BALANCE.
TIME dilation ULTIMATELY proves (ON BALANCE) that ELECTROMAGNETISM/energy is gravity, AS E=MC2 is CLEARLY F=ma ON BALANCE. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 is CLEARLY F=ma ON BALANCE; AS the stars AND PLANETS are POINTS in the night sky. Accordingly, ON BALANCE, the rotation of WHAT IS THE MOON matches it's revolution. TIME is NECESSARILY possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 is CLEARLY F=ma ON BALANCE. The stars AND PLANETS are POINTS in the night sky. Accordingly, ON BALANCE, it makes perfect sense that THE PLANETS (including WHAT IS THE EARTH) will move away very, very, very slightly in relation to what is THE SUN !!! ELECTROMAGNETISM/energy is gravity, AS E=MC2 is CLEARLY F=ma ON BALANCE. Inertia/INERTIAL RESISTANCE is proportional to (or BALANCED with/as) GRAVITATIONAL force/ENERGY, as this balances gravity AND inertia; AS E=MC2 is CLEARLY F=ma ON BALANCE; AS ELECTROMAGNETISM/energy is gravity. GREAT.

The way that I always described c was "the speed at which a massless wave propagates in empty space." Light happens to be one of these massless waves but there are many others.
This perspective is interesting to me, because I work in particle physics and would say the same thing, except I'd say massless particle instead of wave because that's the way I end up thinking about light and gravity more often.
This is especially good because it’s a very intuitive way to understand why gravity travels at light speed. Gravity is also a massless wave- one of the very fabric of space-time itself, and thus being massless (space itself is just an empty vacuum with matter taking up some space) propagates at “light speed”

Wow, you captured the reasoning behind the Lorentz Transformation so beautifully without doing any math! For anyone who has a good understanding of classical Mechanics, I'd also recommend Leonard Susskind's lectures on this.
If you want to keep your sanity, I suggest forgetting Leonard Susskind and going with Lynyrd Skynyrd. Quantum is getting stranger and stranger, and the math is starting to reflect this. It's almost as if quantum theory, or even the universe itself, perhaps, is reacting to the math, which is reacting to quantum theory. The universe is behaving like it isn't real, like it's an illusion, that changes according to what we say it should be.

I've never understood the speed of light, or causality better. That was an absolutely amazing explanation.
It is! And you can show actually show the neat result he mentions with high school tools (derivatives, affine functions, a bit of physics), so it's not quite as out of reach as some people might think
@@ChaineYTXF Agreed. I first learnt Newtonian physics at school, with v=u+at and equations like that and it all made sense step by step. Im always on the lookout for a description just as simple for relativity. And this video is nearly there for me. It seems the best way to approach it is forget about light, forget about weird spooky shrinking spaceships, just go back to how space and time works.
Im going to watch this a few more times and try working through the maths.
The aim being showing Lorentz transformations with meaningful diagrams. Something my brain can hang on to all the way through.
speed of light is made up bs , for example lets say thers no living being that have eyes that can look the light , lets say when u turn on a light the light doesnt move , all the area that is being iluminated by the light is the area where the light source has enough power to reach the more powerful the light the larger the area it will iluminate and be seen in case thers eyes to look at that light , this is why u point a laser in one direction lets say u point it forward but someone who is in back direction will still see the light
"A teensy bit of algebra."
Oh you!
phuturephunk but seriously though the derivation of lorentz transformation doesn't really require higher order maths once you know how 2 reference frame communicates

It's weird, but learning that there was a speed of causality is very comforting to me... The concept of things being limited to the speed of light was like an itch in the back of my mind
Yes, but empty space is not limited by the speed of light and can expand faster, that is why far away cosmic objects are moving away from us faster than the speed of light (because the expanding space in between). The light coming from those objects will never reach us..
how about u stop being dumb believe man made bs , thankfull thers still ppl like me who have common sense that know that light is not actually moving its made up idea , for example a candle 🕯has light in it and its not traveling to ur eyes when u see it , if u see a light it means u are inside of the area that the light is being emitted , why do yall think that the light is traveling to our eyes 🤣
@@joostdriesens3984 the only way "speed of light " could make sense is if u holding a light a something like a flashlight and u move it while the light is on , in that situation then u could say the light is moving but even in that situation the light is not actually moving
I came to this realization from thinking about how a video game is made. The programmer is God and maybe aka the Universe. The light you see is the End Result of the Video game. But the hardware and code behind the scenes must make that light must move faster than light or before the light moves. In fact, they have measured some sort of weird delay between what actually happens and what you see. Almost like when your screen refresh on your monitor to catch up with the computer calculations... maybe that is like quantum information signals can finalize where the waves intersect to create atoms.
@@joostdriesens3984 Something that really blows me away is the concept of overlapping light cones. Like you can see 1 light year further to your "right" than someone 1 light year to your "left". That means that things in that light year of space exist casually to you, but not to that person 1 light year outside of that light cone. Screw uncertainty, it is certain that points in space can exist and not exist at the same time depending on your point of reference.

Ultimately and truly, time is NECESSARILY possible/potential AND actual IN BALANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 IS F=ma. This CLEARLY and truly explains c4 from Einstein's equations. THE FOURTH DIMENSION IS THUS CLEAR, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. BALANCE and completeness go hand in hand. I have mathematically unified physics/physical experience. The stars AND PLANETS are POINTS in the night sky. A PHOTON may be placed at the center of what is THE SUN (as A POINT, of course), AS the reduction of SPACE is offset by (or BALANCED with) the speed of light; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. It all CLEARLY makes perfect sense. E=mc2 IS F=ma. Time DILATION proves that electromagnetism/ENERGY IS GRAVITY, AS E=mc2 IS F=ma. GREAT !!! IT IS CLEARLY PROVEN.

@Geo Thomas The universe doesn't make sense because every observer measures the universe differently. Somebody in motion will have a velocity and his time would be slower than your time if you are at rest. So technically your past is that person's present. Hence there's no reference frame to describe reality. We perceive reality through reference frames. The only thing that you and that guy in motion can agree upon is space time interval or space time. That's the only thing which every single observer can agree upon and that is the only reality. The universe the way you perceive it is only real to you and you only. But only space time is real for everyone

'You can't move faster than the speed of light in the same way you can't move slower than standing'
Great commentary!
The big bang tells us that you can not standstill completely in the universe , the expansion triggered by that moment of the big bang in getting faster and faster.
@@vume7722 | Well, spacetime is increasing, that doesn't mean that you move. You do move because of gravity, though. And the heat in your body.
LOL im crying
Random Guy - No, Vu is correct in a literal sense. We are always in motion because the Earth is in motion and we are on it, the Earth is spinning at around 1000mph in addition to that movement, the galaxy is moving, and everything else in space is moving along with expanding empty space. The consequence is the inability to truly be still and a Universe without a center point.

Yeah, he can't be a real physicist. With that lack of a paunch, the reason he's wearing that t shirt can only be to show off his physique. I know of no real physicists who are into that sort of thing.
He was way hotter with the beard.
We need a finite speed limit for our *experience* of reality, which is also what space-time is fundamentally defined according to. There are unanswered questions about the nature of that experience though, and it's worth considering that on some deeper level, everything does exist as a hole, cohesive, "here and now". Both could simultaneously be true.

At the speed of light, time stops. Light is everywhere all at once. The universe is a web of electromagnetic energy. It's our perception that defines space time and velocity.
Kinda difficult to pick it up watching once, but still interesting. Got the main point, I suppose. Will rewatch it.

This video is a huge jump for people not accustomed to the math he is talking about. Mathematics is a series of stepping stones after all, can't jump multiple steps at a time.
There's really no way around it other than study up and maybe one day this video will be crystal clear.

A lot of mind-blowing revelations from this video, but one that caught me off guard was when he mentions that mass is an impediment to motion. Well yes, obviously it is. But then you think about it even deeper and realize that that's what mass IS, that's what energy IS, is an impediment or slowing down of transferring of information within the fabric of reality, which is spacetime.
Wouldn't energy and matter be the information itself though? It's just slow moving information, not an impediment to information
uh
So in other words...humans aren't meant to go anywhere...since we have mass. And as we all know, as speeds approach C, mass approaches infinity. Light can go this fast because it has no mass.
@@100percentSNAFU Depends on how you measure and define mass.

"Assume that the universe makes sense" Well, that is a pretty bold assumption... :D
Were all sub atomic particles, doing our part without knowing to keep a greater "whole" going with a sense of individuality. Time cannot truly play a part in anything considering it is a common denominator created by man. I love how we revert back to old people who are dead and use old shit math to attempt to make sense of anything we experience. There is no universe and this isn't real. You will "die" its a perceivable common denominator and a system created. Solipsism is real. Your are the center of life. Look around and see that you truly can do anything. All you have to do is make a move and break free from the system you've been forced to believe in and stay original.
I believe Neil DeGrasse Tyson is fond of the quote: "The universe is under no obligation to make sense."
@@trollin456 I looked around and saw a wall. I made a move, ouch! that hurt. The system forced me to believe I'm still locked in. I can't get through that damn wall.
@@JaxMerrick I think the concept that the universe is somehow coherent doesn't mean it has to make sense to each of us personally.
Question- some galaxies are so far away from us that even at the speed of light we could never get to them. If the speed of light is actually the speed limit of causality in the Universe rather than just a speed limit, then how could galaxies this far away possibly have any gravitational effect on us since we are moving apart faster that the speed of causality could reach us?
those responsible to answer are visiting the shrinks.
While today they are too far away for new information to reach us, the gravitational effect information of today left long ago when we were still reachable, it just took until now to reach us. While there is the gravitational effect of the past versions of those galaxies, there will never be such a gravitational effect from those galaxies as they actuallly are right now. Just like we see them now the way they were long ago, but will never see them the way they actually are right now.
@@OzoneTheLynx well said
@@OzoneTheLynx yes indeed, well said.
How could the universe be bigger in size than it is in age? Dosent that prove expansion is faster than the speed of light?
Usually I'm good at this stuff, but frankly, I need this dumbed-down a little.
in short they where all gettign their numbers wrong due to different hypotheses based on current numbers and assumptions . having observed light at a cetain speed does mean its the only speed, and then they base all their calculation on this constant that might be a fluctuating pulse . Imagine if the speed of light was 10 times faster at the start of the univers , that will make the universe 10 time younger than previous thought.
"Assume that the Universe makes sense" --> Good one!! 😂
@Dirk Knight Its in the video!
@Dirk Knight Bruuuh....That statement is in the video & its hilarious, its funny...it wasnt supposed to be interpreted or something.
@Dirk Knight The video is pretty informative tbh. I dont know why you are making a fuzz about this statement....It was just supposed to make a person laugh. lol
I do not think that was a joke. He meant that we need to assume there is a law for it that we can uncover instead of chaos. And by chaos I mean random results.
@Dirk Knight Did you know that the sum of individual mass of proton and electron is more than the mass of hydrogen, which is made of proton and electron? It's like saying 1+1 > 2. Does that make sense? Not at first. But, scientists assume that the universe has to make sense, and that motivates them to search for a logical reason. There are more examples, like quantum tunneling. If you knew anything about modern physics, you wouldn't have said all the stuff you said here. You're actually suffering from Dunning-Kruger effect.
I cannot thank you more for making this video. I've had struggled for years with some questions about speed of light and relativity that I could not find answers to, that I could not quite understand, and they are all amazingly answered in this very video. Thank You!!!!!
Yeah, me too
Physicists should never confuse ponies with unicorns.
On the one hand, this is the most beautiful & comprehensive explanation I've ever seen to answer the biggest quandary I've spent my entire adult life trying to wrap my head around: why does it seem that mass, energy, velocity, time, light, space, entropy, gravity, causality, kinetic energy, atoms and even the 4 fundamental forces... are all different angles looking at the same process? My grasp always ends up feeling half-assed.
On the other hand - while all or most of these angles are entailed herein - it's still the age-old problem that each component causes you to think of how it relates to 50 other considerations... so when he explains 20 details to wrap your head around the one big picture, I find myself caught-up in all the implications of just one of those details. So instead of processing how all the 20 details relate to each other, I can only juggle 2 or 3 at a time with all their 50 sub-considerations each.
Man... sometimes I wish I could just settle on being another jackass endlessly arguing about how "Liberals" or "Conservatives" are to blame for everything.
+Durzo applause actually. love your style, keep it up.
Durzo, look at it this way: If the laws of physics are true then they must be true everywhere, under all conditions of speed and gravity. This was perhaps Einstein's most fundamental understanding. Based on his predecessors' work he was able to show conclusively that the only way this can happen is if the speed of light (or causality) is constant. Assuming that, it all makes sense. But if you deny it then nothing makes sense.
Remember that geniuses have exceptionally clear minds. In 1916 Einstein wrote a slim volume called "Relativity: The Special and the General Theory", subtitled "A Clear Explanation That Anyone Can Understand". He wasn't kidding; the clarity and simplicity of his thinking is astounding and illuminating and very understandable.
A more contemporary example of a genius' point of view is Nobelist laureate and physicist Richard Feynman's "Surely You're Joking, Mr. Feynman." He tells how he cracked safes (during his work at the Manhattan Project!) for the fun of it and it's a marvel of the kind of basic logic that most of us say only afterward, "Yes! Of course!"
Don't settle, Durzo! Keep exploring.
Paul M Actually just a few days ago, for the very-first time in my life, after 10 years of trying to wrap my head around all the implications of Relativity... it just suddenly came together, _fully_, during another hours-long session of over-clocking my frontal and parietal lobes.
I wouldn't be surprised if all the considerations that go into a unified picture end up numbering in the hundreds... it was the most potent version of a "religious experience" I've ever had, but sure enough, once I got it I couldn't imagine how I was ever capable of _not_ getting it. I always knew I had all the pieces but just couldn't fit and hold them all together all at once - but let me tell _anyone_ else who's made it one of their ultimate life's ambitions to learn: despite the insane complexity of every possible consideration, once you *do* get it, you go back and run any one of those brain-strainer pieces through your mind-processor, and the software in your brain - now that it's calibrated right - just zips it through a well-oiled machine and instantly knows where the idea fits and how.

The pony and the monkey just made everything more complicated
Nocturno Yeah. Also that historical stuff was unnecessary I think.
Harish adithya: No, the history is important. Those of us who dispute history are doomed to repeat it (perhaps not a direct quote, but it conveys my meaning: in that regard it is statisticly similar to the price of rice AND tea in China.
Nocturno: Sure it did, but rationally. "Everything" covers a lot of ground and the size of the ground it covers is increasing in harmony with The Law of Entropy in which "entropy is disorder". The Law states that the total amount of disorder in the universe is increasing at the expense of order.
Substitute "CONfusion" for disorder and "Fusion" for order and what do you have? Well, my interpretation is that the amount of CONfusión is increasing at the expense if fusion (CON meaning against and fusion meaning the coming together of- such as in a thermoFUSION atomic bomb as opposed to the fission bomb).
Does that make it less complicated to you?
It did and does make it analogously easier/simpler for my little brain.
Or, as my grandfather (who had only a high school education) told me, " The nore you know the more you realize how much more there is that you don't know".
The monkey and the pony are the reason why.
Its a linear attempt to hint at the fact that 'we' don't know what speed we are traveling at.
Nothing in the universe is linear. There are no straight lines in physics.
The earth (monkey) is rotating around itself = surface velocity.
The earth (monkey) is rotating around the sun (pony) = + oscillating surface velocity 1.
The sun (pony) is rotating in the milky way = + oscillating surface velocity 2
The sun (pony) is rotating around the milky way = + oscillating surface velocity 3.
The milky way might be rotating around another galaxy ... galaxies = + oscillating surface velocities n.
Everything rotates around the centre of the universe.
We don't know where the centre of the universe is ... therefore we have no idea at what nonlinear (oscillating) velocity we are traveling.
We don't know where the famous location of the neutral 'observer' is ...the centre of the universe.
All we can conclude is - if velocity/space/time are related - time itself can't be constant or linear.
We basically know nothing.
The 'Observer' however at the centre of the universe can call himself God, because by adjusting his position he can travel through time and space ... history and future at will.
Everything is relatively related.

I think of it the following way:
Imagine you're in an unknown country and you don't know the laws, then you want tou know the maximum permitted velocity in a highway (analogous to space-tme) and everything you have to measure is a speedometer. Then you find out the max velocity is reached by a Ferrari and you name it "speed of Ferrari". But it is not a speed inherent to the car itself which only complies the maximum permitted velocity, instead is a property of the highway or the law
