Can an explosion create a black hole?

Stellar-mass black holes are born with a bang. They form when a very massive star (at least 25 times heavier than our Sun) runs out of nuclear fuel. The star then explodes as a supernova.

Can a very large star form a black hole?

Most black holes form from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars, which are not massive enough to trap light.) Even bigger black holes can result from stellar collisions.

When a star explodes does it create a black hole?

When the star can no longer support itself, the core collapses completely, forming a stellar-mass black hole, and consuming the nascent supernova without having the massive explosion.

What happens when a star explodes?

The process of collapse releases enough energy to rip the star’s outer layers to bits and blast them into space at several percent of the speed of light. These fragments carry helium, calcium, oxygen, carbon, and other elements into space, where they may someday be incorporated into new stars and planets.

What happens if you go into a black hole?

Of course, no matter what type of black hole you fall into, you’re ultimately going to get torn apart by the extreme gravity. No material, especially fleshy human bodies, could survive intact. So once you pass beyond the edge of the event horizon, you’re done. There’s no getting out.

When a massive star explodes What does it form?

In the massive star case, the core of a massive star may undergo sudden collapse, releasing gravitational potential energy as a supernova. While some observed supernovae are more complex than these two simplified theories, the astrophysical mechanics are established and accepted by the astronomical community.

Can a quasar escape a black hole?

No, a superheated quasar cannot escape a black hole once it crosses the all important Schwarzschild radius, the point at which it is not possible for…

What is an explosion of a star called?

supernova, plural supernovae or supernovas, any of a class of violently exploding stars whose luminosity after eruption suddenly increases many millions of times its normal level.

What is the death explosion of a star called?

supernova
A supernova (/ˌsuːpərˈnoʊvə/ plural: supernovae /ˌsuːpərˈnoʊviː/ or supernovas, abbreviations: SN and SNe) is a powerful and luminous stellar explosion. This transient astronomical event occurs during the last evolutionary stages of a massive star or when a white dwarf is triggered into runaway nuclear fusion.

What happens when a star becomes a black hole?

If neutron degeneracy is not enough to resist the star’s collapse it will continue to shrink until the matter is all compressed into an infinitely small, infinitely dense point called a singularity. This is the centre of a black hole. The life span of a star and its final state are determined by the mass of the star.

How are supermassive black holes formed?

One possible mechanism for the formation of supermassive black holes involves a chain reaction of collisions of stars in compact star clusters that results in the buildup of extremely massive stars, which then collapse to form intermediate-mass black holes. The star clusters then sink to the center of the galaxy,…

How do we owe our existence on Earth to black holes?

So, in some sense, we owe our existence on Earth to long-ago explosions and collision events that formed black holes. On a larger scale, most galaxies seem to have supermassive black holes at their centers. The connection between the formation of these supermassive black holes and the formation of galaxies is still not understood.

What determines the gravity of a black hole?

Black holes are detected by finding the ones that are close to other stars and watching for the radiation (mostly x-rays) given off by matter falling into it before the event horizon is crossed. Check out the Chandra X-Ray Telescope site for x-ray pictures of possible black holes. The key to the puzzle is gravity which is determined by mass.
