...they are not holes. So why to do they call them 'holes'? They are just areas of super compact matter with super gravity. I don't understand why people think its a hole? After all, where's the back of it?
Yes, I think it is very poor term. People think it really is a hole to somewhere unknown but its not a hole at all, more a 'black area/point which is only black due its ability to stop light escaping. Essentially its just a supper compressed lump of matter with massive gravity. .
