Statistics for the stars: it's a gas!

The average number of galaxies in the observable universe: 200 billion. Or maybe more. Who's counting?

Star Count

Currently observing: 100 billion stars. Still got a few billion to go...

Black Hole Density

We're not saying it's a problem. We're just saying it's ... really, really bad. 1 in every 5 stars is a black hole. Don't worry about it. It's just math.

Galactic Speed Limit

Because, you know, the universe isn't going anywhere. 299,792,458 m/s is the speed of light. Don't get too excited. It's not that fast.
