Thanks for this.
I was always interested in black holes. Thing is, they are mostly elusive. We can see what is going on around them but never examine the actual thing due to the whole "laws of nature break".
Still, I am not quite convinced of their true nature or even if they actually exist. Perhaps we are witnessing something different but from our perspective we get all the data distorted.
My pleasure!
Black holes are a prediction of general relativity and what we observed match with this prediction. This is actually the only thing we know that explains the observations.
Now let's move on with your point (that I like a lot): what we observed is something that we have not invented yet. This is possible. But... this not-yet-invented thing will look like a black hole, act like a black hole and could be described like a black hole. In short, it will smell like a black hole. :D
well played :)
