A reminder of our place in the cosmos
The video, from the Hayden Planetarium, zooms out from Nepal to about 14 billion light-years away to show the extent of the known Universe, then zooms back in. The zoom is FTL, so it only takes 6 minutes. If you're going to watch, full-screen would be appropriate.
By someone's calculation, if our galaxy, the Milky Way, were brought down in size to the size of the continental United States, our Sun would be the size of a single red blood cell. And Earth perhaps the size of a malarial parasite.
