“First, you should check out my house. It’s, like, kinda lame, but way less lame than, like, your house.” -Lumpy Space Princess, Adventure Time
Billions of years ago, before the Universe contained clusters, galaxies, stars or even neutral atoms, everything was uniform. Almost perfectly uniform, where the densest regions weren’t even 0.01% denser than average. Over billions of years, those overdense regions have attracted more and more matter and grown under the influence of gravity.
By today, we have the incredible rich, clumpy, structured Universe we exist in. But what about a more perfect Universe, one that was totally uniform? Could that have given rise to us? And if not, what is the limiting factor? It’s a fascinating question, and one science can answer.
