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.
@jackhammer1116 жыл бұрын
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.

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.
@Arevilov32 ай бұрын
@@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

@ShieldAre4 жыл бұрын
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.

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.

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.
@ahmedalshammari18514 жыл бұрын
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.

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”

what did he meant by rate at 1:22 ? because if he meant velocity than he was wrong the papers and elevator and floor were not of same velocity
@JDrocks4ever4 жыл бұрын
by rate, he was referring to gravity being the only force acting on them... other than mass of course I would presume
@megametagrossard33424 жыл бұрын
Wait why wouldn't it be the same velocity ? Gravity accelerates everything ( no matter what their mass ) is at -9.8ms2 ... The force that each object would apply upon contact to the ground would be different though
