What is a black hole?

Has any one thought of a black hole or even thought how it is and what is the story behind it.

Come let’s see what my theory says…

Black holes and like bottles they have a opening like a bottle cap or bottle opening. When u see a open water bottle from far , it looks as if there is a small hole where all the air is going and getting placed inside it.

According to me the black hole has a high gravitational field near it due to some structural alignment of the space and its constituents . so this field will pull all the things near it and due to the suction the place looks dark and the sucked particles go inside the hole and stay as water in a water bottle .

So, this is what I say about the black hole.

This is just my assumption and some of my experiments tell me that this is like this.

Thank you all .
