WEBVTT FILE ﻿1 00:00:00.000 --> 00:00:04.671 ♪ Narrator: Near light speed 101: Effects of near-light-speed travel. 2 00:00:04.671 --> 00:00:09.384 First, a lot of weird things can happen, like time and space getting all bent out of shape. 3 00:00:09.384 --> 00:00:12.012 For example, If you’re moving at nearly the speed of light, 4 00:00:12.012 --> 00:00:16.599 according to the clock inside your rocket, you’ll only take a bit more than half the time to reach your destination 5 00:00:16.599 --> 00:00:19.019 compared to what a clock on your planet would say. 6 00:00:19.019 --> 00:00:21.855 The end result is that while your clock might move normally to you, 7 00:00:21.855 --> 00:00:24.399 you’d see the clocks back home had moved further when you return, 8 00:00:24.399 --> 00:00:27.610 so you might want to reschedule your dental appointments before you leave. 9 00:00:27.610 --> 00:00:29.612 Also, because you’re going so fast, 10 00:00:29.612 --> 00:00:35.076 what would otherwise be just a few hydrogen atoms that you’d run into quickly becomes a LOT of dangerous particles, 11 00:00:35.076 --> 00:00:39.456 so you should probably have shields that keep them from frying your ship and also likely you. 12 00:00:39.456 --> 00:00:45.170 And finally, you wouldn’t want to accelerate too quickly toward the speed of light, because, well. 13 00:00:45.170 --> 00:00:48.339 Thanks for watching, and please... be careful out there. 14 00:00:48.339 --> 00:00:52.427 (silence) ON-SCREEN: EXPLORE SOLAR SYSTEM & BEYOND 15 00:00:52.427 --> 00:00:57.182 ON-SCREEN: NASA logo
