Reality is merely an illusion, albeit a very persistent one. – Einstein
I saw something recently about time travel, and it got me thinking. Einstein’s theory of relativity doesn’t question reality itself but how we perceive the passing of time. It shows that time dilation at near-light speed could slow time for an astronaut so much that a one-year trip for them might mean decades—or even centuries—pass on Earth.
Planned trips to Mars won’t reach these speeds yet, but they do hint at a future where interstellar travel could make time travel a natural side effect of exploring the cosmos.
That’s pretty cool—I think 🤔.
