The One-Way Trip to the Future

A One-Way Trip to the Future What if you left Earth for just two years and came home 4,470 years later? Meet Leo, an ordinary guy who volunteers to ride the fastest ship ever built, traveling at 99.99999% the speed of light. In this animated explainer, we break down Einstein's time dilation with hand-drawn visuals: light clocks, zigzag paths, and why moving faster makes time slow down. Watch Leo's sister Mia grow old in Leo's first week, civilizations rise and fall, and discover real-world proof from muons, GPS satellites, and astronauts. Can Leo ever go back? Would you take the trip? Tell us in the comments!
