The hidden universe????

[srimukh]

Everyone knows that BLACK HOLES suck up everything around them, even light can't escape.

Consider a black hole. It keeps on sucking up the space around it endlessly,

Since there is no limit, infinite amount of space and time are twisted and sucked up,

THERE MUST BE ANOTHER UNIVERSE WITHIN THAT BLACK HOLE!!

 

IS THAT POSSIBLE? Please Explain.

 

Waiting for ur kind response....

Well...I would guess that a "Uni"verse that would be impossible. How can you have two sepereate systems with one being affected as if it was part of one right? You know what I mean like to suck up a whole universe is to suck up everything.

[srimukh]

then what is the controversy? There must be some rate at which the black hole sucks up the up the space. you mean to say that universe is finite?

[Kyrisch]

This is a common misconception. Black holes aren't like cosmic vacuum cleaners, they're just extremely massive bodies. The gravity of a black hole is no different than the gravity of the earth besides the obvious question of magnitude.

[hewj11]

Do black holes actually suck up space? Or is it more of a twist and contortioin of the fabric of spacetime?

[iNow]

As Kyrisch already pointed out, it's no different than things being pulled toward the earth. The same process is involved, it's just that the mass is much greater (or, in a much smaller space).

Another way to think about things is to consider basic geometry. The

surface area of a ball is related to its diameter by pi. A = pi*d^2.

But any gravitating body distorts space so that a light beam travelling

through the center of the body measures a diameter slightly larger than

that indicated by the surface from which it is measured. In the case of

a black hole the diameter measured in this way is infinite, while the

surface area is finite.

Keep in mind a BH is the result of a very large Star, in a process of dying has collapsed to a fraction of its original size having the same gravity of its original mass (density) and/or any other mass that has got into the range to effect. It does not soak up space, but mass. Hypothetically if our star was in fact 1/1000th of its current size, but maintained the same mass we would simple orbit that whatever.

2. How is a stellar black hole created?

 

A common type of black hole is the type produced by some dying stars. A star with a mass greater than 20 times the mass of our Sun may produce a black hole at the end of its life. In the normal life of a star there is a constant tug of war between gravity pulling in and pressure pushing out. Nuclear reactions in the core of the star produce enough energy to push outward. For most of a star's life, gravity and pressure balance each other exactly, and so the star is stable. However, when a star runs out of nuclear fuel, gravity gets the upper hand and the material in the core is compressed even further. The more massive the core of the star, the greater the force of gravity that compresses the material, collapsing it under its own weight. For small stars, when the nuclear fuel is exhausted and there are no more nuclear reactions to fight gravity, the repulsive forces among electrons within the star eventually create enough pressure to halt further gravitational collapse. The star then cools and dies peacefully. This type of star is called the "white dwarf." When a very massive star exhausts its nuclear fuel it explodes as a supernova. The outer parts of the star are expelled violently into space, while the core completely collapses under its own weight.

 

To create a massive core a progenitor (ancestral) star would need to be at least 20 times more massive than our Sun. If the core is very massive (approximately 2.5 times more massive than the Sun), no known repulsive force inside a star can push back hard enough to prevent gravity from completely collapsing the core into a black hole. Then the core compacts into a mathematical point with virtually zero volume, where it is said to have infinite density. This is referred to as a singularity. When this happens, escape would require a velocity greater than the speed of light. No object can reach the speed of light. The distance from the black hole at which the escape velocity is just equal to the speed of light is called the event horizon. Anything, including light, that passes across the event horizon toward the black hole is forever trapped.

Technically our Universe means EVERYTHING thats out there...So a BH is in our Universe, not another or does it likely lead to another...your next question.

you mean to say that universe is finite?

 

Whether or not the universe is finite or infinite is a highly debatable - and more or less meaningless - distinction that depends a great deal on your definitions of dimensions and boundaries and makes very little difference. I know it's difficult to say that science cannot currently answer something, but right here, it's the truth.
