Luchito:
Not quite. You haven't said which invalidated theory it was based on, yet.
Which theory are you referring to?
So, there's no particular reason you think the black hole photo is a fake. You just have a general suspicion, based on nothing in particular?
Previously, you wrote "A scrutiny made on the base foundation of the theoretical background supporting the existence of a black hole can easily show its falseness."
Now you say you don't have a theoretical disproof after all. I guess you're withdrawing that claim, then?
You're a creationist, I take it. How old do you think the Earth is, and what makes you think it's that age?
Of course there are observable phenomena. Far too many to even start making a list. Please try googling "evidence for black holes". Look at reputable sources of information from universities, research institutions and so on. There's a ton of evidence.
Before you start making silly claims, you should at least learn something about the subject you're trying to refute. Don't you think?
