According to Einstein’s special theory of relativity, time’s flow depends on how fast you’re moving.

Although the definition of the second is the same everywhere, the special theory of relativity dictates that clocks tick slower in stronger gravitational fields.

According to the tenets of quantum field theory—an uneasy union between Einstein’s special theory of relativity and quantum mechanics used to model the behavior of subatomic particles—empty space isn’t actually empty.

According to Einstein’s special theory of relativity, this is a physical constant.

Eventually this process launches some stars up to the speed of light in accordance with Albert Einstein’s special theory of relativity, making them what astrophysicists call “relativistic.”
