## What is the radius of a black hole singularity?

A singularity is a point which has zero radius and infinite density.

## What happens when you reach the singularity of a black hole?

And according to the math of Einstein’s theory of general relativity (which is the only math we’ve got), once you pass through the ring singularity, you enter a wormhole and pop out through a white hole (the polar opposite of a black hole, where nothing can enter and matter rushes out at the speed of light) into an …

## Does a black hole singularity have size?

In the real universe, no black holes contain singularities. In general, singularities are the non-physical mathematical result of a flawed physical theory. A singularity is a point in space where there is a mass with infinite density. This would lead to a spacetime with an infinite curvature.

## What would a singularity look like?

What would a singularity look like in the quantum mechanical context? Most likely, it would appear as an extreme concentration of a huge mass (more than a few solar masses for astrophysical black holes) within a tiny volume.

## Why can light escape a black hole?

Answer: Within the event horizon of a black hole space is curved to the point where all paths that light might take to exit the event horizon point back inside the event horizon. Since nothing can travel faster than the speed of light, nothing escapes the event horizon of a black hole.

## What is dark matter and how much of our universe is thought to be dark matter?

It turns out that roughly 68% of the universe is dark energy. Dark matter makes up about 27%. The rest – everything on Earth, everything ever observed with all of our instruments, all normal matter – adds up to less than 5% of the universe.

## Can you ever reach the singularity?

As far as I’ve learned, to reach a black hole singularity, you must first cross an event horizon. The event horizon has this particular property of putting the external universe on an infinite speed to the falling observer.

## Why does time stop in a black hole?

According to Einstein’s theory, time and space, in a way, trade places inside the hole. Inside the black hole, the flow of time itself draws falling objects into the center of the black hole. No force in the universe can stop this fall, any more than we can stop the flow of time.

## Does time exist in a black hole?

For outside observers, a black hole is one solidary element, and there is no proper time inside the black hole, but there is only the observed coordinate time according to our spacetime coordinates.

## Does time stop in a singularity?

When you hit the singularity of a black hole, time stops for you simply because you’re annihilated. This is similar to what happens at the big bang singularity: any observer would have been annihilated by the conditions of the early universe in which the temperature and density diverged to infinity.

## What happens if you go inside a white hole?

No spacecraft will ever reach the region’s edge. Objects inside a white hole can leave and interact with the outside world, but since nothing can get in, the interior is cut off cut off from the universe’s past: No outside event will ever affect the inside.

## Why can’t you leave a black hole?

Answer: Within the event horizon of a black hole space is curved to the point where all paths that light might take to exit the event horizon point back inside the event horizon. This is the reason why light cannot escape a black hole.
