Black holes are commonly known as kind of giant vacuums in space that suck everything into them. However, on NASA.gov, it states that this is a myth. Black holes are simply the evolutionary endpoints of stars that are up to 10 to 15 times bigger than the sun. Black holes are what stars become after they go through the stage of supernova explosion. Black holes contain gravitational forces so strong that not even light can escape, which is probably the main reason why they are so mysterious to people.
At a certain stage in a star’s life it will expand to gargantuan proportions — so much that it is crushed under it’s own gravity after it runs out of nuclear energy.
