How do stars cause black holes when they blow up?

Black holes are formed mainly by collapsing stars. They also form when an object's internal pressure can no longer sustain its gravity. They are formed by stars when it runs out of its "fuel" or they could form due to the ideal gas law (Pressure x Volume= R(constant) x amount of matter x Temperature) when a lot of matter is released without raising its temperature.

Black holes suck things in with an extreme gravitational pull. The force of gravity = (mass of two objects being acted on multiplied by each other) divided by the square of the distance times the Gravitational constant. This explains how Black holes can suck in nearly everything even if it has an unimaginably small mass such as light (thus the name "black hole."

Objects may orbit black holes or possibly collide with them. An example would be our galaxy (the milky Way). At the center of the Milky Way there is a black hole. The entire galaxy orbits this black hole since it is a spiral galaxy. It is theorized that a black hole is at the center of the Universe, and that the Universe will eventually collapse on itself like a rubber band (don't worry though, the human race will long gone before then:) ).

There are many theories surrounding the idea that Black holes "spit out" what they suck in. Some theorize that They contain all matter that they absorb forever, but the only possibility of it releasing any matter would be in the form of "Hawking radiation."

and that's about all that I know about black holes.

hope it answers your question!

Your first question: When a large star runs out of fuel (blowing up or just plain dying) it can no longer support its heavy weight. The pressure from the star's massive layers of hydrogen press down forcing the star to get smaller and smaller and smaller. Eventually the star will get even smaller than an atom. Imagine that for a moment, an entire star squashed up into less space than a tiny atom.

Your second question: Anything that gets sucked into a black hole once it passes its event horizon can not get out. The gravitational force is way to strong that not even light could escape.

Think of the Earth. When you are in outer space you can float around. If you get too close to the Earth you will be pulled in. On the Earth you could leave again in a rocket ship. However if you fall into a black hole there would be no way to get out because the gravity is so strong. Do you know how much mass and gravity a star has? a lot. when it dies it gets smaller and smaller until it is smaller than an atom. When something gets smaller, its mass or gravity gets larger. So just think that through.

Just extra information: Some think that black holes are worm holes to other dimensions to galaxies, planets, universes, etc. Some also think that the Bermuda Triangle is a black hole, because of all of the disappearances of ships and people that have never been found.

Try to watch Stargate or Star Trek on the sci-fi channel to get some more theories.

I really hope i helped you, and if you have anymore questions, i will be glad to help!

HAVE A HAPPY 2009!!!

even as a celebrity with more beneficial than 3 situations the mass of the solar runs out of gasoline, nuclear fusion stops in a fragment of a 2d. without the rigidity of radiation to carry the outer layers of the repute up, those layers fall down very unexpectedly onto the middle starting to be an extreme marvel wave that overcomes all resistance, and the middle collapses forming a black hollow. The outer layers of the repute then rebound causing a supernova. All thousands impression area and time because all thousands produce gravity. in accordance to Einstein, gravity isn't some other thing beneficial than the warping of area-time. A black hollow is so vast and dense that no longer even mild can get away it. A black hollow contains a singularity on the middle and an imaginary floor said as an adventure horizon. some thing that enters the shape horizon is pulled inexorably in route of the singularity. Black holes could very last for trillions of years, yet they do radiate what's termed "Hawking radiation" from purely outdoors the shape horizon. The radiation is led to by the escaping of truly one of a pair of digital debris made from the black hollow's gravitational field. the different particle of the pair falls into the shape horizon. The freed digital particle then turns right into a real particle, and the mass of the black hollow is for this reason dwindled. All black holes will finally disappear as Hawking radiation.

Gravity. Gravitational collapse of the core into a neutron star from a Type II, Type Ib or Type Ic supernova, if it becomes too massive, more collapse into a quark star (2-3 solar masses), and more collapse, until the matter vanishes from existence, crushed and annihilated by the tidal forces of the black hole at anything over 5 solar masses.

Gravity is able to bend and shape spacetime, so if you have enough gravity, you can bend spacetime to have an infinite slope, where all paths lead to exactly one point in the universe. The area where this infinite slope begins is called the event horizon, the literal point where all paths lead to is called a singularity. This is looking at black hole geometry, to which you can easily find a picture like this, to confirm with yourself the process. Nothing escapes, because it is annihilated when it comes into contact with the singularity.

I'll explain this as easy as possible - when the star becomes too big, the mass is enormous. It gets bigger and its gravity gets bigger either. There comes a moment when the gravity of the star is so big that none light can leave the star anymore. That's called a black hole.

The Star explodes and becomes a very small object with a very high mass which we call a black hole. A nearby black hole called the Cygnus X1 is only 3 million meters in diameter. This is 4 times smaller then Earth. I cannot explain why nothing appears once sucked into a Black Hole. Nobody can. It is an undiscovered secret. My opinion is that it gets crushed into such small pieces that it is not visible. :)

The star collapses into an infinetly small ball of mass called a singularity. The singularity has immense gravity and causes things to be pulled in very strongly.

The best way to picture this is to picture a bowling ball on a trampoline, imagine that the ball is a star that died, this star becomes very small and very heavy when the ball explodes you are left with a curvature so deep that it sucks all matter and light in to it.
