What benefit could one have in learning about black holes? Is it the same as a game, jus a way to kill time and have something to talk about?

Well, we can talk more about Donald Trump and HRC if you'd prefer....;-D...

Understanding them completely could be the key to understanding the entire universe.

Vote for Trump he loves the uneducated. 

That's more painful for sure lol.

and you seriously believe any one human mind can do this?

There is no subject in the world that I understand completely. How about you?

How can you say that? How many of President Trump's books have you read? He is far more educated than Hillary, all of Hillary's education is simply in political maneuvering. I bet she doesn't even know how to cook or do laundry.

Isn't it Hillary who has said she wants to take what man of us have learned and get rid of it?

I mean having a complete physical theory that's compatible with both general relativity and quantum mechanics. I don't know that it's beyond human capabilities.

1. Understanding our environment, as going to a movie about black holes at the planetarium.
2. To explain the science to kids your friends have, just in case they don't understand what they were seeing.
3. Space and astronomy is a fascinating field that's also fun to learn.
