A black hole is an object with a gravitational field so powerful that a region of space becomes cut off from the rest of the universe – no matter or radiation, including visible light, that has entered the region can ever escape. The lack of escaping electromagnetic radiation renders the inside of black holes (beyond the event horizon) invisible, hence the name. However, black holes can be detectable if they interact with matter, e.g. by sucking in gas from an orbiting star. The gas spirals inward, heating up to very high temperatures and emitting large amounts of light, X-rays and Gamma rays in the process while still outside of the event horizon. Black holes are also thought to emit a weak form of thermal energy called Hawking radiation.
While the idea of an object with gravity strong enough to prevent light from escaping was proposed in the 18th century, black holes as presently understood are described by Einstein's theory of general relativity, developed in 1916. This theory predicts that when a large enough amount of mass is present within a sufficiently small region of space, all paths through space are warped inwards towards the center of the volume. When an object is compressed enough for this to occur, collapse is unavoidable (it would take infinite strength to resist collapsing into a black hole). When an object passes within the event horizon at the boundary of the black hole, it is lost forever (it would take an infinite amount of effort for an object to climb out from inside the hole). Although the object would be reduced to a singularity, the information it carries is not lost (see the black hole information paradox).
While general relativity describes a black hole as a region of empty space with a pointlike singularity at the center and an event horizon at the outer edge, the description changes when the effects of quantum mechanics are taken into account. The final, correct description of black holes, requiring a theory of quantum gravity, is unknown.

no person BELIEVES something a pair of black hollow. ideals do no longer remember. we've theories that anticipate - would not propose we've self assurance it to be thoroughly authentic. it truly is a greater mature point of thinking - it truly is authentic on condition that the assumptions made are valid. If we stumble on the assumptions exchange the it truly is not any longer authentic. perception never enters into it. The predictions made are that as you go the horizon of the black hollow you will no longer be conscious any instantaneous exchange. debris that surrounds you nevertheless surrounds you. and that's all you notice for eternity. The debris around you. Now what you notice once you swap around is that the universe is speeding up swifter and swifter. What you don't understand occurring is which you're slowly acceleration. quickly you will pass earth gravity. What happens next interior reason grotesque. you notice on earth we are truly close to to the exterior and the earth isn't so super so we don't experience the version in gravity between our heads and our ft. no longer so interior the black hollow. As we loose fall like satellites we are somewhat accelerating swifter and swifter - quickly the gravity at our ft ( assuming we went it ft first) would be lots greater advantageous than at hour head- in certainty we get chop up in 0.5 because of the pull. And we get pulled into smaller halves as we flow down extra and the gravity distinction will advance for an identical volume fo length. Assuming we live to tell the tale by some ability all we are nevertheless seeing the crap we floated in with!!! we are only acceleration swifter, and relativisticly we see the universe velocity up consequently.

A different universe, typically labeled the Imaginary Universe.
Within this universe, stars connect with each other outside of this universe's time.
The Imaginary Universe contains antimatter, whose primary property is that, when compared to Real Time, during any Significant Moment, the speed and vibrational velocity of each particle exceeds the speed of light.

Hyper compressed matter and energy. As not even all the energy manages to escape from it, except for a beam at each side from its center.

Probably space garbage and comet fragments. Lots of space dust because it's a vacuum cleaner!

It has heavy gravity. From all the Very dense matter in it.

you won't live to tell the tale. when you go into a black hole your body is compressed and become a singularity

dark matter (matter that doesn't give off light like stars)
whatever the dark matter is it is probably really big
