This kind of stuff is beyond any man's imagination. I mean, how can you even understand what the speed of light is (if you really think about it). Then thinking about something that has a mass this big, and powerful like that is just insane. These people talking about this stuff don't even slightly understand what is going on.
If someone is watching us, they must have laughed at them explaining (or rather not explaining) what we know about these black holes. The scope of discoveries to come is large, and I hope before I die we can understand better our universe.
Another topic would be Big Bang. Can you even imagine how it all started? Is it even possible that all the universe was contained in like an egg? That makes you feel like you are nothing. If you begin to understand how big all this is, you might start to feel sick because you realize we are NOTHING. Ego dissolution of some sort
