Quote by Stephen Hawking
Time travel used to be thought of as just science fiction, but Einstein's general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out.

Summary
This quote suggests that time travel, once solely considered a concept in science fiction, might not be entirely impossible. According to Einstein's general theory of relativity, it proposes the idea of warping space-time to such an extent that traveling in a rocket could potentially enable one to return to a point in time before their departure. In a concise manner, the quote highlights how scientific theories open up the possibility of time travel, challenging previous assumptions about its feasibility.
