@jackhammer111

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.

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.

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.

From this simple postulates of gravity and acceleration being the same, Einstein predicts that light can also be bend by gravity.

Correct me if i am wrong: Consider standing inside the elevator- You and the elevator which is retarding upwards . If it is moving upwards with acceleration g. g is not the force acting on the elevator or you. It is the resultant of all the forces acting on you. Now considering the idea of weight measurement- The normal reaction would come out to be 2mg. So I could'nt understand the idea of weightlessness here.

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.

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”

But he couldn't properly justify that what that force is, why is it happening and what causes it? Therefore, people just thought that gravity is an invisible force and is making everything fall and making planets in orbit. Einstein came along with his general and special relativity and told us that gravity is not a force, but rather it's just the bending of space-time around the presence of heavy matter.
