I get this question a lot: What good is physics and cosmology? Nobody except the smart brains understand them anyways. Why should I care?
There are a couple of reasons, I think. Awe. is the first one. But you can’t eat that. It’s good entertainment wise which is good in itself and can be enlightening. But more importantly is the practicality of math and logic. Behind every scientific quest is a set of logic and math and deduction ready to be tested. It is a continual testament of practicality of math and logic. And you should care because math and logic although not necessarily of the cosmological kind could help you go a lot smoother in life. And most importantly unlike other pre-conditions in life, this stuff is learnable.
