The universe is a complex and fascinating place.

These yellow boxes are explainer boxes. They explain things like you're five. I know you're much smarter than a five-year-old but sometimes starting with small words is better. Small words make it easier to decide if you want to read all the fancy grown-up words. You can close these yellow boxes if you want to.

Also, the little blue thingies have more explainy words. They look like links to other websites but they're not. Links, images, blue thingies... they all have explainy words if you hover over them. All you have to do is hover over them. So you may want to use a mouse.

If you don't see any blue thingies, that's probably because you're a nerd and you turned off Javascript. I promise that this website doesn't have any Javascript cooties or icky ads. I hate icky ads. But I like Javascript so this website has lots of gizmos and other neat stuff that you'll need Javascript for. If you don't know what Javascript is, don't worry, that means everything should work fine for you.

Ain't nobody here but us chickens.
