black hole is one of the strangest objects in the universe. A vacuum
cleaner and a black hole are very similar but there is only one
difference, a vacuum cleaner uses suction power to pull things into it. A black hole uses gravity to pull things into it.
Why is A Black Hole Empty?
A black hole isn’t empty, it is full of material that is squashed into a very small place which causes the gravity to be very strong there.
Are There Different Types Of Black Holes?
There is two types of black hole, a Supermassive black hole and a Stellar mass black hole. A Supermassive is the bigger of the two types of black holes and a stellar-mass black hole is the smallest.
The way that a Supermassive is made
is equal to a million Suns squashed into one place. The Stellar
mass is made when a big star dies, causing it to explode in a very
bright light. Astronomers call this explosion a supernova, the material that is left, forms a black hole.
How Far Is The Nearest Black Hole?
The nearest black hole is about 16 quadrillion kilometres from Earth, that is about 1,600 light years away.
