While others could have many as 400 billion stars,or even more.There are three kinds of galaxies like,Spiral,Elliptical,and Irregular.The only difference between the three is what shape they are. THESE ARE GALAXIES! How do the planets stay in space without falling down? There is gravity in space.First you need to know about gravity is.Everything in the Universe is attacted to everthing eles.The force depends on how big things are and how far apart they are.You and the earth attract each other.Because the Earth is much bigger than you are you can only notice the fact that is pulling you towards it.This gives you what you understand as weight.If you went far away from the earth you wouldn't be attract to it so much. What is a black hole? H ave you ever vacuum your bed room?When you do ,watch closely because you will see dirt ,and crumbs start to move towards the vacuum cleaner.A black hole is similar to a vacuum cleaner,cleaning up debris left behind in outer space.It is not suction power that makes things fall into a black hole.Suction would not be strong enough.Instead a black hole uses the power of gravity to pull things towards it.
