“In 1915, Einstein developed his ideas to form the General Theory of Relativity, in which he considered objects that were being accelerated with respect to one another. He compared the forces of acceleration and gravity and found them to be indistinguishable. For example, an astronaut standing in a rocket on a launch pad would feel himself pressed against the floor because of gravity. If the same rocket was in outer space and not affected by gravity, but with its engines turned on so that it was accelerating, the astronaut would again be pressed against the floor. If the acceleration due to the engines were the same as the acceleration due to gravity, the astronaut would have no way of telling whether the rocket was at rest on the earth or accelerating in outer space unless the looked out of the window. Einstein stated that the attraction to the Earth of a rocket that is resting on a launch pad is equivalent to the acceleration of the rocket. So although in three-dimensional space, the rocket remains stationary, in four-dimensional space-time the rocket is in motion along its world line. The upshot of this motion in space-time is that gravity also makes time run slower”( Kulkarni, 2011). What are the kinds of time travel and what are the ways that will help scientists prove that time travel is possible? The two kinds of time travel are time travel forwards and time travel backwards, which will be made through time
