00:00right now you're seeing the past light takes time to travel so when you look at the sun
00:07you're seeing it as it was eight minutes ago look at distant stars you're seeing them years
00:14even thousands of years in the past some of those stars might not even exist anymore
00:21but their light is still traveling still reaching you so every time you look at the night sky
00:28you're not seeing space you're seeing history
