The Nature of Space and Time

Einstein's theory of general relativity says that Time can be bent, stretched and squeezed, and the four-dimensional fabric with a huge mass creates a dimple, or bending of Space-Time, causing gravity.

This effect of time dilation is proven using GPS satellite technology in space, making a...

Einstein's special theory of relativity applies only to steady, unchanging motion through space-time, not accelerating motion like an object falling toward Earth.

• It troubled Einstein that his theory didn't include gravity, and his battle to incorporate it made symmetry central to hi...

Albert Einstein held that space and time together made up the universe's fabric that could stretch and compress. Einstein suggested that the shape of spacetime is what gives rise to the force of gravity. A concentration of mass, like the earth or sun, ben...
