THis week I will tell you about black holes in our galaxy and our solsar system.
When the star ten times more massive than our own Sun, explodes (Supernova) it leaves behind the strangest phenomenon in the Universe.What could it be? Of cousre the black hole. After the explosion what is left behind is heavy core of subatomic particles,or in other words a Neutron Star. Well what is a nuetron star? Nuetron star is a very little star with an enormous density. Its interesting that one teaspoon of the NUetron star could weigh around billions of tons.
In space everything is time and Space. The upsetting things are that the black holes are pulling everything around them closer to the center of the hole. It makes sense that the black holes are creators of the galaxies since they are pulling planets and stars towards the spiral center. Each galaxy has a Black Hole and occasionally galaxies collide together because of the gravitational pull from the larger black holes. It is expected that in 5 billion years Andromeda galaxy will collide with our Milky Way galaxy. Lucily I on the other hand will not be aliive when that happens. What do you think about black holes.
