what are some questions you have about the universe?

Answer 1

The Black Hole theory bothers me. They say it's like a whirlpool, sucking in stars with ultra-powerful gravity. The debris gets crushed as it nears the vortex. As Depok says, we are mostly nothing. I can almost comprehend how a planet could be reduced to a cubic inch of matter that weighs a billion tons. But I've heard that the matter doesn't exit the Black Hole. Logic demands that what goes in must come out.

Also, this BS about aliens visiting us. I believe there is life on other planets. Either some, many, or most solar syatems have a planet or two with living plants or animals. I think that intelligent life is much more rare though. I'd personally guess that less than one in a few hundred or thousand living worlds support intelligent life. Of those, again, only a rare few would progress far enough to achieve space flight, and of those who did, only a few would solve the light-speed problem.

So the NEAREST star, Alfa Centuri, is 2 point something light years away. There's probably no life there. So how many stars are within, say, 20 light years from Earth? Okay, so let's assume there are a few species capable of making the trek. Why would they bother? Because we have radios? Hardly. We are just too far away to be worth the time, expense, and bother. There must be a thousand planets between us and them that are far more interesting (and rewarding) to visit.
