Understanding reality is a great adventure, isn't it?
I personally think the existence of black holes is proven beyond doubt... but it is true that the past few decades has shown that the universe is capable of astounding us monkeys...
I dont have a problem with good science suggesting silly things- sometimes the silly becomes fact. Black holes do exist, but do we understand them? I doubt it...
The important thing to notice is this: Has there ever been a time (in human history) when humans could EXPECT that the view of the cosmos would change several times in their lifetime?
We are lucky to be alive now- I love the way this game is going!
