What is a black hole in space? My theory of the black hole is that it's a doorway to another space similar to our own. Other's say it's a death trap that swallows up everything in its path and crushes it into oblivion. Till there is nothing left.
Some believe it shrinks the objects into compact particles. While continuously spinning in a circle. Dropping them into another peace of data like on a disc or cd. Except for there is no end to the amount of data being stored.
In many theories there is a possibility that each one is correct until proven otherwise. Another theory is that the black hole is a black mirror. That can be easily slipped threw. And so that would mean that there are planets the same as ours with numerous galaxies the same as ours. Just everything is in a reversed rotation.
Whatever the case, we can be for sure that if something goes in. It will never return. Unless there was a possible way to get close enough to keep attached a camera probe on a tag line, and then sent into the black hole to collect pictures. This may be worth a try.
