No, a duck is a fowl; a species of bird. We gave it the name duck and can associate the actual animal with the name we gave it. A black hole, according to theory is a collapsed star. The collapsing causing such massive gravity that anything around it gets pulled into it; even light. I can prove to you what a duck is. I can go to one and point it out and say “there’s a duck”. If it lets me, I can reach out and touch it, smell it, and even kill it and cook it for dinner. You cannot do this with a ‘black hole’. You can only theorize that what you are observing from millions of light years away that a black hole (the name science has given this event) is a collapsed star and that it’s actually pulling everything in to it.
No, a black hole is a region of space time where gravity is so strong that nothing, not even light can escape. Gravitational collapse (what you're talking about with the star) is one of at least 4 theories on how they form. So now, ask me the question on how black holes form. The answer we aren't sure yet.
I can observe human behavior and deduce from that behavior that there is – theoretically – a God. From written documents, to people erecting massive structures, to archeological evidence I have deduced (just as you have with black holes) that there is a God. Although I can’t actually show you this God, you can’t touch it, smell it, or kill it and cook it for dinner, the behavior around it indicates to me that it exists.
Then I contend that Mickey Mouse is god. He has countless followers who wear his image on clothing and put them up in their homes. Books, film and other media too numerous to mention are dedicated to him. People live by the principals and morals described in those works (friendship, fairness, forgiveness). And roughly 120 million people per year attend his 5 "temples" world wide. Entire channels on television are dedicated to him. And let's not forget that in a national poll, Mickey Mouse was more recognizable than Jesus to young children.
