Can a black hole become a star again?

The simplest way to see this is probably that a black hole has a much higher entropy than a star or even another type of stellar remnant of even vaguely similar mass and so there simply could not exist a spontaneous process by which a black hole develops back into a star.

Does a dead star turn into a black hole?

A black hole can be formed by the death of a massive star. At the end of a massive star’s life, the core becomes unstable and collapses in upon itself, and the star’s outer layers are blown away.

Why won’t our star become a black hole?

No. Stars like the Sun just aren’t massive enough to become black holes. Instead, in several billion years, the Sun will cast off its outer layers, and its core will form a white dwarf – a dense ball of carbon and oxygen that no longer produces nuclear energy, but that shines because it is very hot.

What star creates a black hole?

neutron star
When a star burns through the last of its fuel, the object may collapse, or fall into itself. For smaller stars (those up to about three times the sun’s mass), the new core will become a neutron star or a white dwarf. But when a larger star collapses, it continues to compress and creates a stellar black hole.

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.

What happens to a star after a supernova explosion?

What’s left over after a supernova explosion is a ‘neutron star’ – the collapsed core of the star – or, if there’s sufficient mass, a black hole. Average-sized stars (up to about 1.4 times the mass of the Sun) will die less dramatically.

Did Hubble see a supernova blink out a black hole?

When a massive star expends its fuel, its core collapses into a dense object and sends the rest of its gas outward in an event called a supernova. What’s left is mostly neutron stars or black holes. And now, Hubble seems to have seen a supernova blink out — suggesting it captured the moment when a black hole took over.

What are some examples of stars that die of mass?

Black holes, neutron stars and red dwarfs – it all depends on the mass. Stars die because they exhaust their nuclear fuel. The events at the end of a star’s life depend on its mass.
