Is a black hole a hole in space time?

A black hole is a region of spacetime where gravity is so strong that nothing — no particles or even electromagnetic radiation such as light — can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

Where does the matter in a black hole go?

singularity
It is thought that the matter that goes into a black hole gets crushed into a tiny point at the center called a “singularity”. �That’s the only place that matter is, so if you were to fall into a black hole you wouldn’t hit a surface as you would with a normal star.

Can NASA stop a black hole?

The collapse triggers a supernova explosion that blows off the star’s outer layers. But if the crushed core contains more than about three times the Sun’s mass, no known force can stop its collapse to a black hole.

What if Earth bumped into a black hole?

The same gravitational effects that produced spaghettification would start to take effect here. The edge of the Earth closest to the black hole would feel a much stronger force than the far side. As such, the doom of the entire planet would be at hand. We would be pulled apart.

What is a black hole in physics?

(Grades K-4) series. 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.

Why can’t we see black holes in space?

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.

Where is the black hole at the center of the Galaxy?

Sagittarius A* is the black hole at the center of the Milky Way galaxy. Credits: X-ray: NASA/UMass/D.Wang et al., IR: NASA/STScI. This article is part of the NASA Knows! (Grades K-4) series. A black hole is a place in space where gravity pulls so much that even light can not get out.

Will the Earth ever fall into a black hole?

Black holes do not go around in space eating stars, moons and planets. Earth will not fall into a black hole because no black hole is close enough to the solar system for Earth to do that. Even if a black hole the same mass as the sun were to take the place of the sun, Earth still would not fall in.
