What happens to the absorbed mass in a collapsing black hole?

In summary, the conversation discusses the possibility of black hole collapse and what happens to the mass it absorbs. There is theoretical and observational evidence that black holes can evaporate through Hawking Radiation, which releases mass and energy back into the universe. There is also a mention of Rovelli & Vidotto's "Planck Star" explanation for the fate of black holes in LQG.

So I was reading threads and i came across a question on what happens when a black hole collapses. As I was reading the responses, I saw some people commenting in which they asked if the mass the black hole absorbed was released when the black hole collapsed. If it did would the black hole release the mass and expand continuously until it ran out of mass to expand from? If it did would it cause an explosion type expansion? And one final question, would it cause another big bang?

Black hole collapse? Is there any theoretical or observational evidence that this is possible?

If the black hole were to disperse itslef in any way that you perfer considering we haven't observed any black hole disapearing, what would happen to the matter that the black hole pulled into its singularity?

Black holes do evaporate. All of the mass/energy comes back to us.

How would it come back to us?

Hawking Radiation. Mostly photons, plus matter and antimatter particles in equal numbers. Lots of antimatter.

Oh i forgot about hawking radiation. Sorry for asking so many questions.

I will believe anything that hawking logically explains.

And if you want an explosion scenario rather than just boring old Hawking evaporation, look at Rovelli & Vidotto's" Planck Star" description of the possible fate of black hole in LQG

1. What is the "The Collapse of a Black Hole"?

The collapse of a black hole refers to the process by which a massive star, usually at least three times the mass of the sun, runs out of fuel and collapses in on itself. This collapse creates a gravitational pull so strong that even light cannot escape, resulting in a region of space with extreme curvature known as a black hole.

2. How does a black hole collapse?

A black hole collapses when a massive star runs out of fuel and can no longer generate enough energy to counteract the force of gravity. As the star's core collapses, its density and gravitational pull increase exponentially, eventually becoming so strong that even light cannot escape.

3. What happens during the collapse of a black hole?

During the collapse of a black hole, the star's outer layers collapse inward, creating intense heat and pressure. This leads to the formation of a singularity, a point of infinite density and zero volume. The singularity is surrounded by the event horizon, the point of no return for anything, including light, that gets too close to the black hole.

4. Can a black hole collapse completely?

According to current theories, it is not possible for a black hole to collapse completely. The singularity at the center of the black hole is thought to be a point of infinite density and zero volume, meaning it cannot physically shrink any further. However, the black hole can continue to grow in mass as it consumes more matter and energy from its surroundings.

5. What are the potential effects of a black hole collapse?

The collapse of a black hole can have a significant impact on the surrounding space and objects. The intense gravitational pull can distort the paths of nearby objects, and the extreme heat and radiation can disrupt and destroy any matter in the vicinity. Additionally, the collapse of a black hole can release powerful bursts of energy, known as gamma-ray bursts, which can have a wide range of effects on the surrounding universe.
