Natural phenomenon : Black hole

Blackhole 

     Black hole is a part of space time wich have a big gravitation so the particle and electromagnetic radiation such as light can't go from it.

     Black hole formed from the star who run out of flue so it can do the fusion so it makes the gravitation and radiation not balance. The gravitation become very high but the radiation become very low. The big gravitation make big density and can make two option. The first one is the star died become thing that have a heavy mass with high density or its explosion become Supernova. After become Supernova that also two probability that it can be new star that we call it nebula or things that have big gravitation and will pull anything around it that we call Black hole.

     There are three type of Black hole. First is Mini Black hole, Stellar Black hole, and Supermassive Black hole. Mini black hole is small black hole. stellar black hole is black hole wich have shape 20 times of earth and it happens so far from the earth in interstellar. and suppermassive black hole is the big black hole wich scientist prediction happen in the center of the galaxy.

     We can detect Black hole by observe the star because black hole invisible so if there are the star constellation gone in some area and the area became black we can assumed that maybe black hole .

Black hole works like big vacuum cleaner. black hole can grow because of the things that pull into it if there just a few things it will be died and gone.
