of Relativity ?​

Answer 2

Answer:

Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels.

The theory of special relativity explains how space and time are linked for objects that are moving at a consistent speed in a straight line. ... Simply put, as an object approaches the speed of light, its mass becomes infinite and it is unable to go any faster than light travels.
