If You Traveled at the Speed of Light

[00:00:00]Buckle up. What would actually [music] happen if you hopped in a spaceship and hit the ultimate cosmic speed limit? At 186,000 mi per second, the universe breaks. The stars in front of you would squish together [music] and turn blindingly blue. That's the Doppler effect on steroids. Behind you, pitch black. But here's the most insane part, time dilation. According to Einstein, the faster you move through space, the slower you move through time.

[00:00:23]For you, a round trip to the center of the galaxy might feel like a quick 20-year cruise, but when you finally land and back home, over 50,000 [music] years would have passed on Earth. You'd step out onto a barren wasteland.

[00:00:36]Everyone [music] and everything you ever knew would be dust. You'd basically be a relic of the past, staring out at the future. Would you still take the ride?
