phred952:And one question is what really happens beyond the event horizon?
Postulation, theories, abound
No one really knows, spegetification is talked about, then crushing gravity to a point smaller than a pin head. Designated as a singularity.
Pyridine shift
I do not concur with this old theory. I believe the Black Holes, are the engines that drive the galaxies building blocks. Substance of any type entering, does not get compressed into a singularity, it is moved from 1 place to another.
Sure, its ripped apart, if conjecture of immense gravity is correct. Then reduced to its atomic structure. As all stars are essentially hydrogen, my theory is that hydrogen, the most plentiful substance in the universe, poops out the other end of the vortex.
Becoming dark matter, which coincidently, was decided, makes up the darkness between all things celestial out there. WOW! What an original thought.
They still have not found any, or it's origins. Or figured out it's hydrogen.
Think about how many different ways a star meets it's demise, and, its end results. All are monumentally violently, deadly results. Pulsars, Quasars, red giant, etc.
Then think about "billions & billions" thank you Mr. Sagan, of them getting sucked into a vortex. With all the repercussions, gamma ray bursts, x-rays, etc.
All that power, fission, & fusion has to be taking place. A nuclear device of unimaginable proportions is being created inside there. Constantly imploding & exploding.
We are going to be left with an infinite amount of big bangs, rather than just one, as postulated, when all galactic materials, do an about face, and slam back into each other, supposedly starting all of what we know, over again.
Pffft!
Think up some chit, write a paper, submit it to the science academy, become a PhD, and start getting grants, to figure out errant shots here. At least you'll have substance at your finger tips.
