When I was young, in my elementary school, my father sent me a book named “A Birth History of Time”; this book is written by Stephen Hawking. From that time, I started interesting in the universe. I have written so many articles about this theme in my blog in Chinese. Unfortunately, blog sever crushed in 2009, I lost all my productions. Today I’d love to share my collected information to you all.
We are leaving in the earth. Out of the earth, there is an infinite space around us. In all ages, no one knows how old and how big the universe is. Most of people buy in the standpoint that is Big Bang. Big Bang means a blast.
Many years ago, universe just is a singularity; in other word is only a point. After the Big Bang, universe begins to swell up and gradually coming into sampler today. Universe including many galaxies, galaxy including black hole, quasars, define, planets, secondary planets, dusts and particles.
We know, solar system is a part of Milky Way galaxy. There are night planets in solar system, according to the distance from the solar they are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. But in 2006, scientists proclaim the Pluto is not planet anymore, because people found the mass is not enough. Actually, it’s a piled of ice.
So far, our technology only can explore partial Milky Way galaxy, and they found three black holes there. What is back hole? Black hole is a region of space from which nothing, not even light, can escape, reflecting nothing.
Why black hole can absorb everything event the light? We know matter is constituted by molecules; molecule is composed by atoms; atom is structured by atomic nucleus and electrons. Electrons are scatted outside of atom, electrons has the major bulk of atom, think about it, if outside electrons all coming into the inside, the atom will change to very some. If we compact the earth, the earth’s bulk will change to small like pingpang ball. But the quality is still. So the gravity also still. Now we are absorbed on the earth, after compaction we are also absorbed on the earth, we, the people are all over the world, will stand on the pingpang ball. Black hole’s quality is not like a earth, they are very big. Purportedly, the smallest one‘s quality is 40 times the Sun. the largest is imponderable.
Very interesting, I hope someday people can finger out all problem of universe that we didn’t know yet.
