17. Black Holes
Updated: Oct 2, 2021
Introduction
Black holes look like round circles that are black in space. They can suck in anything and, not even light or time can escape.
The names of black holes
There are four types of black holes. Here are their names:
1. Stellar black holes
2. Supermassive black holes
3. Miniature black holes
4. Intermediate black holes
The Stellar black holes
The stellar black holes are the most common black holes ever created. They are common because when a star almost three times or more than the size of the sun runs out of hydrogen and helium it implodes and compresses into a stellar black hole. They can keep sucking for more than the age of the universe right now, 13 billion years!

Supermassive black holes
Supermassive black holes are the largest kind of black holes we have found so far. They are also the strongest we have found. You know the bright thing in the middle of each galaxy?
That is actually a supermassive black hole you are looking at. This type of black hole forms when a bunch of giant glowing stars smash into each other.
Miniature black holes
This kind of black hole hasn’t been observed so I can’t tell you any facts about it. So far, they are just theoretical. They were first thought to exist by Professor Stephen Hawking in 1971.
Intermediate black holes
Intermediate black holes are in a class that the radius of one is 142 times the size of our sun. Scientists think that these black holes form when another type of black hole from the same group of black holes finds another black hole. They both circle each other for millions of years and spin faster as time goes on. Once they touch each other, they explode and become a bigger black hole. This is an intermediate black hole. Intermediate black holes are still very big!
What would happen if you flew a spaceship into a black hole?
Nobody really knows what it would be like to cross the event horizon of a black hole. Scientists think that once you cross the point at which time and light cannot escape, you would be spaghettified (stretched out into long pieces like spaghetti!)

Great Topic! will we ever be sucked into a black hole?
it is the supermassive black hole called sagittarius A
I have no idea where the closest one to earth is Henry. Do you know?
A very interesting article.
Unless you were able to travel extremely fast anything on a human scale would not survive the gravitational effects long before you were any where near the event horizon.
Where is the nearest black hole to Earth?
I would like to think that black holes take us to another dimension that has a lot of planets like earth on the other side. Don't know if I would like to end up like spaghetti though.....
