What lies inside a black hole?

According to theory, within a black hole there’s something called a singularity. A singularity is what all the matter in a black hole gets crushed into. Others say that the singularity is actually a whole surface inside the event horizon.

What is the answer for black hole?

A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can’t see black holes.

Does anything come out of a black hole?

The only things that a black hole can spit out come from outside the event horizon, from particles to conventional photons to even the Hawking radiation that get their energy from the black hole’s mass itself.

How do physicists know what’s inside black holes?

Artist’s illustration of the silhouette of a black hole surrounded by stars. The short answer is, physicists don’t know. A somewhat longer answer is, it depends on whom you ask. What’s inside a black hole? We understand what happens outside the black hole as you approach its event horizon, that infamous point of no return.

What would happen if you fell into a black hole?

It might be turbulent, twisted, or any other number of things. One thing’s for sure, though: the tidal forces would kill you (see below). According to theory, within a black hole there’s something called a singularity. A singularity is what all the matter in a black hole gets crushed into.

What is the black hole information paradox?

Hawking’s calculation posed a paradox — the infamous “ black hole information paradox ” — that has motivated research in fundamental physics ever since. On the one hand, quantum mechanics, the rulebook for particles, says that information about particles’ past states gets carried forward as they evolve — a bedrock principle called “unitarity.”

How big is the black hole at the centre of our galaxy?

Thanks to German astronomers, we now have the most accurate measurements yet of the giant black hole that sits at the centre of our galaxy. And what a beast it is: as wide as Earth’s orbit around the sun and 4.3 million times more massive than our home star. Lucky, then, that it is 27,000 light years away.
