A black hole forms when a very massive star explodes, leaving behind a very dense remnant core. If the star is massive enough, the core will be compressed to a very small volume with extreme density, generating a powerful gravitational force that is characteristic of black holes.

a black hole is formed when a star much larger in mass than our sun begins to create iron in its core, and goes supernova. the star itself implodes and sends the energy outward. but if the core collapses completely, then time "halts" at the moment of complete collapse at the event horizon, but beyond that, the star continues to collapse until it creates a singularity.

thus, a blackhole is born.

A very huge star (50 times as big as ours, billions of times the size of earth) "burns" enough of it's hydrogen fuel off by converting it into nuclear energy, radiation (heat and light) that it's mass is diminished, which means it's gravity is diminished, enough so that it is not enough to hold back the extreme explosive force of the nuclear fusion going off in it's core (imagine millions of nuclear bombs going off at once, that is what is at the core of every sun... literally). So it's explosive power finally outwrestles it's gravity and it explodes, but because it's mass is still so massive at this point it collapses back in on itself, so dense that it's gravitational force multiplies, collapsing matter and pulling in everything that comes too close.

Black holes, once considered hypothetical bodies, are detectable through their effects on celestial bodies as well as the intense radiation given off by matter passing by not close enough to be pulled in, but not far enough to escape, which "slingshots" around and around the black hole's gravitational field emitting large amounts of invisible X-ray radiation, visible by special x-ray sensitive telescopes billions of light-years away orbiting earth.

What happens when a black hole forms?

It starts taking in matter.


What happens when a black hole forms in a black hole?

A black hole can't really form inside of another black hole. If you think of a black hole forming after a star goes supernova, then there isn't really a star to go supernove inside of the already created black hole. In fact, there isn't even any space inside of the blak hole for anything to happen. Two black holes can join together, but they wil eventually go to one.


What forms a black hole?

When a massive star dies, gravity forces it to fall in on itself, and the result is a gigantic explosion called a hypernova. The leftover of a hypernova is a black hole.


Adjective or adverb a black hole is the remains of a supermassive star after a supernova?

Adverb: "A black hole forms when a supermassive star collapses after a supernova explosion."


What is a collapsed star with strong gravitation?

depends on how strong.... when a massive star's life ends and it collapses on itself extremely quickly... it forms a black hole and the black hole has an EXTREMELY strong gravitational pull..... so i think the answer is black hole


What factor determines if a neutron star forms or a black hole forms after a supernova explosion?

The factor that determines whether a neutron star or a black hole forms after a supernova explosion is the mass of the collapsing core of the star. If the core's mass is between about 1.4 and 3 times the mass of the sun, a neutron star is formed. If the core's mass exceeds about 3 solar masses, a black hole is likely to form.


IS Light is the only thing that can escape a black hole?

Yes, light is the only thing that can escape a black hole's gravitational pull. Nothing with mass, including matter and other forms of energy, can escape a black hole once it crosses its event horizon.


What is an object with gravity that is so strong nothing can escape it?

a black hole is your answer and it is because when a main sequenced star collects to much energy the gravity stops and forms a black hole


How is a black hole caused?

a black hole is caused by a supernova, then the black hole forms. the matter sucked in and gets shot through a worm hole. after the wormhole the matter gets shot out a white hole. the wormhole is impossible to see, for witch this hard to belive for it goes from one end of the galixy to the other endhope i helped!


How is a blackhole formed in our universe?

A blackhole is formed in our universe when matter falls onto the black hole and that forms an accretion disk that is heated by friction. The black hole does not allow anything to escape it.


do comets come from a black hole?

No. Comets are made from the leftover material when a solar system forms.


What is accretion disc of black holes?

that`s all the matter its sucking in. and this forms a flat disc around the black hole similar to the disc around Saturn only the disc around the black hole is spiraling in on itselfs
