Hello everyone
It has been a long time since I wrote something here. I really miss writing here and sharing stuff with you. For long time I have been trying to find a book makes me want to read, and after buying various diffrent typs of books I found my favourit book that called how science works. This book discusses diffrent phenomenas and explaine them in a simple way.
Today I read about black holes and I already heard about this phenomena before but i know nothing about how it happens or even why. Black holes is a region of space where the gravity pull everything including the light which makes the black hole invisiable but it is detectable by some kind of instrumentation. The scientests demonstrated the existence of the black holes as a result of stars death. Basically any stable star has two forces work in opposit directions to give balance; inward gravitational force; outward pressure from nuclear reactions. Once the nuclear reactions stop, the star dies and it loses the balance between those forces. The losting balance leads to explod the star. If the core of the star remains after the explosion, it keeps shrinking and collapsing and form a black hole. This phenomenon aroused many questions, can this happens to the earth or to a star near to the earth, what happens to the things go inside the black holes, what if the sun become a black hole, what will happen if a person goes close to a black hole. I really enjoyed reading about this phenomenon and I hope you felt the same.
