Justin Tesla Chan That means you didn't understand General Theory of Relativity. With Elevator thought experiment, he showed how one can switch on and off gravity artificially. We do that all the time in space station with circular motion.
what do you mean switch of on and off ? Actually, in relativity language, the space station isn't moving "with a circular motion". It is moving in a straight line in curved space/time. If it was circular motion there would be centrifugal force felt by people on board as a force away from the center. A ball being spun on a string is moving in a circular motion and you have to hold on (apply a force, an acceleration) to it to keep it from heading off in a straight line. That is totally different than a body in orbit around a body of a larger mass. The space station and the moon are falling (accelerating at 1 g) into a gravity well. On the space station it does not feel like you're moving in a circle. If the space station was moving in free space a light year away from our solar system it would feel no different on board. It would be a body moving in a straight line in uncurved space/time. That is the same as moving in a straight line in curved space/time.
The best feeling in physics is making sence of a concept through mind experiments and then applying math to a paper but when it comes to mathemtics the best feeling is when you try to approach a problem with different ways and in the end one of your stategies solve it
True, sometimes i feel stupid but when you find the answer in your own way with applied mathematics, you will feel how happy it is. It turned me from feeling stupid into curiosity.
His idea that gravity and acceleration were the same thing was the beginning of his idea, not the end in itself. He soon builds on it and discovers that gravity is but a distortion of spacetime in the presence of matter - and the resulting field ultimately causes the acceleration.
R-mg= ma and mg- R= ma this is followed in elevator similar concepts that in pulling a roller is very easy as compared to push it reaction force supports in this query..
Technically relativity says that the only acceleration is from the floor. You're being accelerated constantly by the normal force keeping you up. The geodesic for an object at our speed and position relative to the earth is inward. When you free fall, you're finally just moving in a 'straight' line in spacetime. Our planet, meanwhile, is following the same 'straight line' in space that's curved by the sun such that the straight line maintains a mostly constant distance to the sun. Gravity is not a force on an object, but a distortion of spacetime. This also explains why quantum mechanics is failing to find it, since they're mostly ignoring Relativity and looking for a force-carrying particle.
@@tristanridley1601 they're not ignoring relativity. They're using the concepts from relativity and trying to quantize it like the path integral formulation using a modified action from GR but there are a lot of problems with these theories The thing is that mass and energy cause this distortion in spacetime but they're best described by quantum mechanics at a small scale so there must be some connection of gravity with it too If they do find a theory using a force carrying particle, it should produce einstein's equations in the classical limit

oZzIbRiDgE GaMiNg I'll try explaining it with a E.g. Sun is a heavy mass which curves the space time around it... This curved spacetime around the sun dictates how matter surrounding it like planets move
oZzIbRiDgE GaMiNg imagine space with no mass in it. This has a net called spacetime. It is perfectly straight until there is mass. Mass warps the spacetime around the mass making it curve. Mass will always follow spacetime so if something passes by it will move along the curve towards the other mass. This is what we call gravity.
"weightlessness is the concept potrayed here,its actually quite simple , we feel weightless when the acceleration due of elevator and acceleration due to gravity becomes equal"
its more than that. Its the realization of the equivalence of gravity and acceleration. There is no experiment you could conduct in the closed elevator car that would tell you if you were in an elevator that was in space and accelerating towards the ceiling at 1g versus a stationary elevator car on the ground floor of a building on Earth.
I feel this is misleading as it misses or does not properly emphasize a major component of why this is important: The realization that if you didn't know what is outside the elevator, based on the acceleration you couldn't tell if you're on an elevator that is stationary on the surface of a planet and gravity is pulling you down, or if you're in a rocket ship in outer space that is accelerating and you therefore feel the elevator floor pushing on you. And therefore acceleration and gravity are the "same". For example, if you were in a spaceship that was accelerating, and had a beam of light that started from one wall the elevator and ended on the opposite wall, the beam of light would curve slightly because during the time the light travelled, the elevator would accelerate and move slightly out of the way, and the beam wouldn't hit the spot on the wall that it would have if the ship wasn't accelerating. And then you realize that because acceleration and gravity behave in the same way, the same thing should happen to an elevator that is "stationary" and at rest on the surface of a planet. And from this you instantly get some clue about the fact that gravity bends light.
U are correct...i was also feeling same ,how acceleration and gravity becomes same..how he deduced that from that experiment is not explained properly 🙄
I really wanna experience the era where men like this were alive, where we still didn't understand how the universe worked, It was all theories, talk, experiments, math, men like einstein!

N+ma=mg and when the string of the lift breaks...a gets equal to g I.e. a=g..N(apparent weight)=mg-ma or in this case N = m(g-g) which is weight is equal to=0 therefore we don't feel weight
Actually, isn’t it the strong or weak force of the atoms/particles of the elevator that pushes you up if the elevator moves up, and the gravitational force that pushes you down when you stand in the elevator. So both forces may feel the same, but they don’t have the same cause.
@@ifuwinuwin5923 Technically you are at rest if you fall und the earth is accelerating towards you. It's hard to imagine but it's just like that. You accelerating in a spaceship with one g or standing on earth is physically the same.

Quite often the most simple thing we all thought very mundane, holds the brightest star of the dark sky. We like to just glanced over it, and never took a second time to look back. That's why "I should've seen it before" came.
When objects fall to the ground, gravity causes them to accelerate. Acceleration is a change in velocity. i have a doubt if gravity and acceleration are same is gravity also equals the rate of change in velocity??
It is so simple and striking because everyone knows F=m•a Which have a consequence that every rigid mass object attracts every other rigid mass object with a *constant* acceleration, that's gravity

Einstein was a poor student but a brilliant THINKER. This documentary on him is a message for the brilliant STUDENTS that they 'may not' be good at imagination.
@Alfonse Bun Nowadays you have all the tools to learn. Even if he had a great mentor, it doesn't mean anything when in the end it all come down to us and in this case Einstein. Like a prodigy can see things further in some area and not being capable to see new things, Einstein was the reverse. However people always forget that Einstein always trained his mind. Reading books, discuss with friends, etc. He did study to reach were he was at. He might had not been as hardworking as Edinson or Tesla, but he did surely hardwork.
I'm confused. wasn't the idea that gravity results in acceleration between masses already thought up well before Einsteins time by someone, whom I believe had the name Isaac Newton.
That’s the difference, Newton’s thought of gravity as a force of attraction between two masses. But Einstein theory of general relativity tells us that gravity is simply an acceleration, produced by the fact that matter curves spacetime.
@@ahmedalshammari1851 yeah newton was the what and einstien is the how. The video just doesnt do a great job of explaining the relationship between the two theories.
U are correct...i was also feeling same ,how acceleration and gravity becomes same..how he deduced that from that experiment is not explained properly 🙄
Newton treated it as a force. The force being proportional to the masses of the two objects and proportional to the inverse square of the distance between them. Einstein on the other hand treated it as a curvature of spacetime caused by masses. The apparent force is just the result of the objects moving towards one another along the curved spacetime. To quote John Wheeler: “Mass tells space-time how to curve, and space-time tells mass how to move”
Correct: Mathematics cannot explain the probability and uncertainty principles of quantum-mechanics. Nor can it explain quantum entanglement. And yet physical and observational experiment can prove logic and reasoning despite the mathematics.
I think that it was because of inertia that he felt like that. The elevator moved too fast and Einstein’s inertia made him stay where he was, which felt as if he was floating. And, when the elevator was rising, Einstein’s inertia mad him stay where he was, but he felt the floor because the floor was rising.
The equivalence principle states that it is locally impossible to determine if one is accelerated or in a gravitational field. So if you are inside the elevator you won't know what is accelerating you.
the thing is the elevator and einstein are both accelerating at the same rate, that is "g" so if everything which is accelerating at the same rate as you then you would feel as if you were in a inertial frame
@@theboiyoulove5124If you are accelerating, you would not feel as if you are in an inertial frame, even if things around you are accelerating at the same rate because there would be an inertial force on you
I can't believe he was so excited for this imagination Here in India in class 11th we are taught about this thing as pseudo force. Alas we are not able to realise the beauty in it.
Good point, but Einstein's idea of "acceleration and gravity the same thing" is more subtle than that of psuedoforces in accelerated reference frames; it's not just that acceleration and gravity feel the same; it's the assertion that they ARE the same and you can never tell the difference because there is none. As a simple example of why this idea is so powerful is considering what would happen if you saw a beam of light when you are accelerating up in the elevator: you would see the path of the light beam curve downwards because you are going up - this is intuitive - but if acceleration and gravity are the same, you would also expect light to curve down when it moves across something exerting a strong gravitational pull: this is exactly what happens in gravitational lensing! And Newton's theory can never predict this phenomenon because it will say that the light beam will not curve due to gravitational pull as light is massless... But from experiments we know that it's Einstein's theory which is correct and light does in fact bend around massive objects even though light itself is massless.
Are these clips from a movie or series? Somebody please help this looks so interesting all these different clips and trying to find out where it’s from and watch it all
Weightlessness. The normal force would be zero as the downwards acceleration of the elevator increasead in magnitude and equated the magnitude of earth's gravity acceleration. This is incredible!

@@ahmedalshammari1851 yeah newton was the what and einstien is the how. The video just doesnt do a great job of explaining the relationship between the two theories.
U are correct...i was also feeling same ,how acceleration and gravity becomes same..how he deduced that from that experiment is not explained properly 🙄
@@ahmedalshammari1851 thanks for nice explanation
Newton treated it as a force. The force being proportional to the masses of the two objects and proportional to the inverse square of the distance between them. Einstein on the other hand treated it as a curvature of spacetime caused by masses. The apparent force is just the result of the objects moving towards one another along the curved spacetime. To quote John Wheeler: “Mass tells space-time how to curve, and space-time tells mass how to move”
Scientists: using highly complicated and specialised techniques of mathematics
Einstein: using simple logic and reasoning.
Correct: Mathematics cannot explain the probability and uncertainty principles of quantum-mechanics. Nor can it explain quantum entanglement. And yet physical and observational experiment can prove logic and reasoning despite the mathematics.
I think that it was because of inertia that he felt like that. The elevator moved too fast and Einstein’s inertia made him stay where he was, which felt as if he was floating. And, when the elevator was rising, Einstein’s inertia mad him stay where he was, but he felt the floor because the floor was rising.
Possible.
The equivalence principle states that it is locally impossible to determine if one is accelerated or in a gravitational field. So if you are inside the elevator you won't know what is accelerating you.
the thing is the elevator and einstein are both accelerating at the same rate, that is "g" so if everything which is accelerating at the same rate as you then you would feel as if you were in a inertial frame
@@theboiyoulove5124If you are accelerating, you would not feel as if you are in an inertial frame, even if things around you are accelerating at the same rate because there would be an inertial force on you
So, falling with an elevator is the happiest thought of his life. :3
I can't believe he was so excited for this imagination
Here in India in class 11th we are taught about this thing as pseudo force.
Alas we are not able to realise the beauty in it.
Good point, but Einstein's idea of "acceleration and gravity the same thing" is more subtle than that of psuedoforces in accelerated reference frames; it's not just that acceleration and gravity feel the same; it's the assertion that they ARE the same and you can never tell the difference because there is none.
As a simple example of why this idea is so powerful is considering what would happen if you saw a beam of light when you are accelerating up in the elevator: you would see the path of the light beam curve downwards because you are going up - this is intuitive - but if acceleration and gravity are the same, you would also expect light to curve down when it moves across something exerting a strong gravitational pull: this is exactly what happens in gravitational lensing! And Newton's theory can never predict this phenomenon because it will say that the light beam will not curve due to gravitational pull as light is massless... But from experiments we know that it's Einstein's theory which is correct and light does in fact bend around massive objects even though light itself is massless.
Are these clips from a movie or series? Somebody please help this looks so interesting all these different clips and trying to find out where it’s from and watch it all
It's a TV show. It's called "Genius Einstein".
He is a genius!
Why is the elevator boy glued to the elevator, during acceleration upward, and during downward falling. is he a super being.
Flat Earthers be like: :"SEEEEEEEEEEEEEEEEEEEEEEEEEEE earth is moving upwards, even Einstein said that"
If time-space was one-dimensional.
The earth is falling in an arch and we are floating above it.
a = g(acceleration due to gravity)
So underated series on the internet
Einstein is so keen in changes and observation, that he can notice that, but here you are, your gf is cheating in front of you and you didn't notice😂
U😂😂😂😂😂
Einstein brain is not hardwired for emotions
Weightlessness. The normal force would be zero as the downwards acceleration of the elevator increasead in magnitude and equated the magnitude of earth's gravity acceleration. This is incredible!
every knowledge come from imagination
This got me to science
i dont get anything i just love watching this
