THE ESSENCSE OF A BLACK HOLE

Everyone states a black hole is the death of a galaxy or a wormhole to another universe--- BUUUTTT what if it is actually the big bang therory being played out, can we say this is not the way life first started eons ago the central collection of universal matter to be comprosed for the creation of life and new planets again. and yes we do have a Black hole in the center of our galaxy also. so is this galaxy going to reborn anew or totally destroyed?

[Realitycheck]

A black hole is a collapsed star which has sufficient mass and density to develop a gravitational pull so strong that it overtakes the release of light, ie. photons. Black holes appear to be larger in size than they actually are because the border of this excess gravitational pull extends out past the size of the actual mass that produces the gravity. Once you get past this event horizon, light is able to escape the gravity.

 

Supermassive black holes also exist in the center of galaxies, but I can't say much about how they are thought to have formed. Either way, they are not "holes" per se or passages to wormholes, but rather large balls of matter, denser than anything imaginable, that don't release any light.

It should also be noted that blackholes also radiate through a process called Hawking radiation.
