Chasing Time Fact, Fiction, and Physics

Update: 2025-12-10

Description

Time travel — it’s been a dream, a nightmare, and a Hollywood blockbuster. But is it just science fiction, or could there be a grain of truth hidden in physics? From Einstein’s relativity to quantum weirdness, this episode of A Dash of Info unpacks the real science behind one of humanity’s wildest ideas: traveling through time.

We’ll explore how astronauts aboard the International Space Station already experience tiny glimpses of time travel, how gravity near a black hole can slow time to a crawl, and why wormholes might be the universe’s ultimate shortcut. Then we’ll dive into the paradoxes that baffle even the best physicists — from the “grandfather paradox” to the “bootstrap loop” — and how theories like the Many-Worlds interpretation might solve them.

Pop culture helps bring it all to life, too — from Back to the Future and Interstellar to The Flash, whose time-twisting adventures reveal how even one small change in the past could rewrite history.

Whether you’re a fan of physics, philosophy, or superheroes, this episode asks the biggest question of all: If time travel were possible, could the universe handle it?
