A black hole sucks all the mass and energy which passes it, even light. So it's called black hole.

What do you call a center point of a black hole?

a singularity


How long can someone live in a black hole?

You can't, if you call it in the black hole being inside the event horizon; that is if you mean inside the 'black' portion of the hole. If you say near the black hole, then it depends on how close and how much thrust, fuel and mass your ship has.

What do you call the center of a black hole?

The center of a black hole is called a singularity, where a huge amount of matter is crushed into a single point. That's scary, isn't it?

A brown dwarf star or a black hole

The collapses star gets squeezed by collapses gas and turns into a black hole.


What is the difference between a Scchwarzschild and a Kerr black hole?

A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.

Is it possible to make a call in a black hole?

In the canonical sense it would be highly difficult to make a call from inside a black hole. It would certainly be impossible to make a call from the inside to the outside, since no information can exit the event horizon once crossed; thus, the call would have to be placed entirely from within it. One would have to consider the means by which the person making the call and the person receiving it entered the black hole; both would have had to survive crossing the event horizon and thus have survived the intense gravitational field, tremendous tidal forces (for all but the largest black holes) and the radiation from the accretion disk and polar relativistic jets. Presuming this is possible, there would remain the functionality of the infrastructure to make a call, such as the presence of operational public switched telephone network equipment, whose existence inside a black hole would once again be highly unlikely, and whose entrance into the black hole subject to the same stresses. Further, presuming all these factors to be favorable, the conditions inside the black hole would have to be conducive to placement of a call; the physics of spacetime inside a black hole are counterintuitive and likely not yet fully understood. Some theories posit that the black hole is a boundary to another universe, and/or that we are ourselves within a separate universe bounded by the event horizon of a black hole observable from a universe from which ours originated; although these theories are speculative, in this case it might be possible that all the calls we make are from within a black hole.


How did Switzerlands natural land forms form?

Chuck Norris roundhouse kicked a giant pile of rocks, which turned into a black hole. He then killed the black hole with his fists. The dead black hole then descended on earth and formed what we call now "Switzerland". Thank you, you useless dickweed

What does the black hole do to the star?

A black hole originated as a star, that is, the star converted to a black hole.
