How is a black hole formed simple?

How is a black hole formed simple?

Stellar black holes are made when the center of a very big star falls in upon itself, or collapses. When this happens, it causes a supernova. A supernova is an exploding star that blasts part of the star into space. Scientists think supermassive black holes were made at the same time as the galaxy they are in.

What is inside black hole?

The singularity at the center of a black hole is the ultimate no man’s land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down. And it doesn’t really exist. Something has to replace the singularity, but we’re not exactly sure what.

Is it possible to create a black hole?

To make a black hole, one must concentrate mass or energy sufficiently that the escape velocity from the region in which it is concentrated exceeds the speed of light. Some extensions of present physics posit the existence of extra dimensions of space.

Does time stop in a black hole?

Near a black hole, the slowing of time is extreme. From the viewpoint of an observer outside the black hole, time stops. For example, an object falling into the hole would appear frozen in time at the edge of the hole.

How long can a black hole last?

If black holes evaporate under Hawking radiation, a solar mass black hole will evaporate over 1064 years which is vastly longer than the age of the universe. A supermassive black hole with a mass of 1011 (100 billion) M ☉ will evaporate in around 2×10100 years.

Do we live in black holes?

Can a black hole be destroyed?

Since nothing can escape from the gravitational force of a black hole, it was long thought that black holes are impossible to destroy. But we now know that black holes actually evaporate, slowly returning their energy to the Universe.

Can you live in a black hole?

The resulting uninhabitable black hole would have such a powerful gravitational pull that not even light could avoid it. So, should you then find yourself at the event horizon — the point at which light and matter can only pass inward, as proposed by the German astronomer Karl Schwarzschild — there is no escape.

How many black holes exist?

Judging from the number of stars large enough to produce such black holes, however, scientists estimate that there are as many as ten million to a billion such black holes in the Milky Way alone.

Can Earth entered a black hole?

Will Earth be swallowed by a black hole? Absolutely not. While a black hole does have an immense gravitational field, they are only “dangerous” if you get very close to them.

Can you turn Earth into a black hole?

Chandra’s scientists have stated that to turn the Earth into a black hole, we would have to contract its entire mass to such an extent that it would become the size of a marble. This contraction will cause the planet to collapse on itself and eventually turn into a black hole.

Do wormholes exist?

Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They’ve never been seen, but according to Einstein’s general theory of relativity, they might exist.

Has anything been sent into a black hole?

Fortunately, this has never happened to anyone — black holes are too far away to pull in any matter from our solar system.

What is the closest black hole to Earth?

The black hole Gaia BH1, seen in this artist’s concept near its Sun-like companion star, is the closest black hole to Earth discovered so far.
