What is the scariest thing about black holes?

These black holes are dark most of the time, but when their

gravity pulls in nearby stars and gas

, they flare into intense activity and pump out a huge amount of radiation. Massive black holes are dangerous in two ways. If you get too close, the enormous gravity will suck you in.

What are the 4 types of black holes?

There are four types of black holes:

stellar, intermediate, supermassive, and miniature

. The most commonly known way a black hole forms is by stellar death. As stars reach the ends of their lives, most will inflate, lose mass, and then cool to form white dwarfs.

What is interesting about black holes?

as many as ten million to a billion such black holes

in the Milky Way alone.

Does a black hole ever end?

But don’t expect a black hole to disappear any time soon. It takes a shockingly long time for a black hole to shed all of its mass as energy via Hawking radiation. It would take

10100 years

, or a googol, for a supermassive black hole to fully disappear.

Can a black hole swallow the Earth?

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. … It would get very dark of course and very cold, but the black hole’s gravity at our distance from it would not be a concern.

three reasons. … Most of the time they are inactive, but when they are active and eat stars and gas, the region close to the black hole can outshine the entire galaxy that hosts them. Galaxies where the black holes are active are called quasars.

How big are black holes?

It has a diameter of

about 78 billion miles

. For perspective, that’s about 40% the size of our solar system, according to some estimates. And it’s estimated to be about 21 billion times the mass of our sun. So there you have it, black holes can be millions of times larger than suns and planets or as small as a city.

What happens if a person goes into a black hole?

. Spaghettification: A black hole would stretch an astronaut’s body into a thin ribbon, since the gravity pulling on their feet is so much stronger than on their head. …

Why is space black?

Because

space is a near-perfect vacuum

— meaning it has exceedingly few particles — there’s virtually nothing in the space between stars and planets to scatter light to our eyes. And with no light reaching the eyes, they see black.

Will the sun become a black hole?

However,

the Sun will never turn into a black hole

, because it is said to have less mass than needed to turn into one. When the Sun is about to reach its end and run out of its fuel, it will automatically throw off outer layers turning into a glowing gas ring known as a “planetary nebula”.
