This section also explains what dark matter is, how we ascertained its existence, and why it is relevant to the Universe’s structure.
I am unnaturally excited by this.
How does one make the leap from "I can't figure out what is wrong with my measurements" to "the universe contains secret matter that doesn't show up anywhere but in the errors of my calculations"?
I mean, there was an episode of ST:TNG where Doctor Beverly Crusher concludes "Well, if there's nothing wrong with me, there must be something wrong with the universe!" But that's crazy talk.
Ok, I guess that is a pretty easy jump. But how do you get other people to buy into that? Because that sounds impossible.
It's not like forming a cult or something, is it?
