the nature of universe

I chose about the black hole as the H.W topic.




“Black hole”
When I was a junior high school student, my science teacher told me about a black hole. Until then, I was interested in a black hole.

A black hole is a star which affects a very strong gravitation to everything around the black hole, even light. It is thought that it was made by contracting a huge gas cloud, and the size is bigger and bigger nowadays. The research about a black hole has kept; however, any scientists can’t observe it directly. But in the universe, it is thought that there is a super-massive black hole which is the biggest one, and also it is said that the white hole exists in the universe.
The black hole can be a role that sucks everything around it into itself. By contraries the role of white hole is getting out everything that was sucked by the black hole.

So it means that if there were the black hole and the white hole in the earth, we could travel in the twinkling of an eye!!!!!
I wish the day came true by the time I will die.
