Black Holes?

Question

What are are the theroys on how a black hole works, and what happens when you go through one? How are they created? Is there any estamites on how many are in the universe as of now?

What are are the theroys on how a black hole works, and what happens when you go through one? How are they created? Is there any estamites on how many are in the universe as of now? Any other facts would be kewl.

Lol oops didn't mean to repeat.

I'm asking for theroys, I knwo its imposible for a human to contact earth or anything if there sucked in, but what are some possible happenings if you go trough?

Answer 1

There are a whole lot more black holes then we ever thought.
Recently, it was discovered that most galaxies have super massive black holes at their center, including ours. Why these black holes are inactive is unknown, but a pretty important question.

A Black Hole is gravity, pure gravity. When a huge star collapses its dieing embers can condense down into a neutron star. The gravity of a neutron star is so strong that the protons and electrons of an atom are squished together and pushed out. The result is pure neutrons; that's neutronium and that's a dark star.

When there is a star larger than that which can create a black hole then the collapse doesn't end. There is no place for the force to go until it collapses the star to a single point. Thus creating a black hole. It is a stellar body that was thought to emit no radiation, only absorb it, so it was called a black hole.

A black hole is nothing but pure gravity. The matter that formed it has condensed to a single point, a concept that is unimaginable just like infinity is.

When things fall into a black hole they accelerate as the pull of gravity increases. As things get closer then they start to suffer tidal stresses. If you go into the black hole head first then the gravitational forces at your head are stronger than those at your waist, which are not as strong as those at your feet. Thus you body gets pulled into the black hole stretching it. The black hole is pulling you inside, but the force of gravity is stretching your body and pulling it apart as you go deeper into the area around the hole.

When something is this close to such a strong gravity field it is hard to escape, the speed required is greater and greater. Eventually, the escape speed approaches that of light and so escape is impossible. This is called the event horizon of the black hole. Since light itself cannot escape from a black hole at this point you can no longer see what is happening on the other side; the interior of the black hole.

If black holes were perfect then they would continue to absorb everything in the universe including each other until only one grand black hole would remain. But, black holes aren’t truly black, they do emit radiation; Hawking Radiation, as theorized by Steven Hawking. This radiation will mean that eventually a black hole will evaporate.

Things are simple here until your realize that most of the Universe is missing. For a while it was thought to be hiding inside of black holes, but now we know of it as dark matter and dark energy. Einstein called them the cosmological constant and thought of it as his greatest mistake. But, his only mistake was that he was right. If you look at the speed of the universe, and calculate its age then you understand how much energy was needed in the great bang to get things started. Well the equations don’t balance, that’s what the cosmological constant does. And that energy and matter are most of the universe. This is the only way to explain why the speed at which the universe is spreading is still increasing. It should have slowed down by now, but it hasn’t.

Black Holes are just temporary weigh stations for matter. It falls inside and eventually comes out. To make matters worse black holes DO EMIT more than just Hawking radiation. Tearing things apart is not easy to do and that requires a lot of energy. Also when the matter tries to fall into the black hole it can’t get out of the way of itself. Because of this black holes admit x-rays and other radiation. Technically the radiation isn’t coming from the black hole, but if it weren’t for the black hole then the radiation wouldn’t be there.

So black holes aren’t black, they aren’t sucking all the matter of the universe and they are not the end of the universe.

Answer 2

Most black holes come from "Red Giant" stars, stars that near the end of their lives


It swells and goes big, quickly eating up all the gas in it. Nuclear fission-fusion go faster


Then eventually, after using up all the energy, the star explodes.


if the star is small, it will end up as a white dwarf star. If it is big, it ends up as a Pulsar, a star that sends radio waves, or it could also end up as a Black hole.


A black hole could suck up everything, even light could not escape it (thats why it's called a black hole).


I don't know how many black holes are there in the whole universe today.


our star, the Sun, would probably end up as a whie dwarf star.

Answer 3

A black hole essentially absorbs everything around it, including light.
No one knows what will happen if you go through one, as there would be no way of getting back, nor contacting earth; the hole would absorb all radio waves, etc.
But I'm guessing you'd die.

Answer 4

I'd recommend you read the book " A brief history of time" by Stephen Hawkings. All your doubts will be cleared. You'll have people to tell you about black holes and you can learn about it through wikipedia as well, but please read this book. I assure you, it's very interesting.

Answer 5

It is just a pin point in space, with almost infinite density, and enough gravitational pull to bend light. Not a tourist destination.
