Einstein's theory of general relativity predicts that the space-time around Earth will not be only deformed but also twisted by the rotation of the planets. In his theory of special relativity, Einstein has determined that the laws of physics are the same for all non-accelerating observers. He proved that the speed of light in a vacuum is the same and does not matter the speed at which an observer moves. Thus, he found that space and time were interlinked into a single scale called as space-time scale and so the event that takes place at the same time for one observer might take place at different times for another observer.

Hey Friend...... :-)
Here is Your answer
When the theory of relativity appeared in the early 1900s, it upended centuries of science and gave physicists a new understanding of space and time. Isaac Newton saw space and time as fixed, but in the new picture provided by special relativity and general relativity they were fluid and malleable.
The theory is based on two key concepts.
1) First, the natural world allows no “privileged” frames of reference. As long as an object is moving in a straight line at a constant speed (that is, with no acceleration), the laws of physics are the same for everyone. It’s a bit like when you look out a train window and see an adjacent train appear to move — but is it moving, or are you? It can be hard to tell. Einstein recognized that if the motion is perfectly uniform, it's literally impossible to tell — and identified this as a central principle of physics.
3) Second, light travels at an unvarying speed of 186,000 miles a second. No matter how fast an observer is moving or how fast a light-emitting object is moving, a measurement of the speed of light always yields the same result.
Starting from these two postulates, Einstein showed that space and time are intertwined in ways that scientists had never previously realized. Through a series of thought experiments, Einstein demonstrated that the consequences of special relativity are often counterintuitive — even startling.

WHO CAME UP WITH THE THEORY OF RELATIVITY?
Albert Einstein. He published the first part of his theory — special relativity — in the German physics journal Annalen der Physik in 1905 and completed his theory of general relativity only after another decade of difficult work. He presented the latter theory in a series of lectures in Berlin in late 1915 and published in the Annalen in 1916.

If you’re zooming along in a rocket and pass a friend in an identical but slower-moving rocket, for example, you’ll see that your friend’s watch is ticking along more slowly than yours (physicists call this "time dilation").
What’s more, your friend’s rocket will appear shorter than your own. If your rocket speeds up, your mass and that of the rocket will increase. The faster you go, the heavier things become and the more your rocket will resist your efforts to make it go faster. Einstein showed that nothing that has a mass can ever reach the speed of light.
