The Cosmic Microwave Backgrounda.k.a. the Universes baby picture

How did we get to now?

We know a lot of stuff:What the Universe looked like early onHow gravity worksHow stars workHow thermodynamics worksetc

So why not just calculate things directly?

Solutions are too complex to solve directly, even with a computer

Break one massively complex problem up into millions of little ones. We discretize the system

All models are wrong.(on some level)Without infinte computing power, we always have to take shortcuts SOMEWHERE.However

All models are wrong.Some are useful.
