Time travel might seem like the province of science fiction writers. However, some scientists believe that time travel is at least mathematically possible. Einstein’s theory of general relativity’s effect on matter warps space and time. In theory, the gravitational force found at the entrance of a black hole might be enough to make time run in reverse. While that’s a far cry from the story told in H.G. Wells’ The Time Machine, it’s just as intriguing to scientists.
‘Wait! So is this a hypothesis, a theory, or a fact?’
