Chapter 1841 (1/2)

Where is this holiday?

This is clearly to accept punishment!

We really know what's wrong, master!

We will cooperate with you in your research!

We don't ask for a vacation any more!

Let's go back to the research!

The wailing dinner is finally over.

After dinner, Shen Yuan and a Ling sat side by side in the open space, looking up at the starry sky above their heads. Don't mention how comfortable they are.

”A yuan, do you think people will become stars after they die?” A Ling asked a very poetic question.

This sentence is probably a sentence that little lovers will ask each other, especially romantic and interesting. Shen Yuan just wanted to open his mouth gently, and heard a voice of the evil scenery ring from one side: ”when people die, they will be burned to ashes. Even if the group bar group is formed into a group, it will be difficult to form a planet if it is thrown out hard to break away from the gravity and rush out of the atmosphere. Generally speaking, stars in the universe are formed in this way. Before the birth of the universe, there was no time, no space, no matter and energy. About 15 billion years ago, in the four empty ”nothing”, an infinitely small point exploded. Time and space from this moment on, material and energy also produced, which is the big bang of the creation of the universe. ”

a Ling who is saying sweet love words in the romantic atmosphere:”... ”

Shen Yuan, who is trying to coax his girlfriend in a romantic atmosphere, said: ”I'm going to coax her.”

Really, they really want to carry a 40 meter knife and cut it!

Who cares how your universe came into being!

Who cares if the universe doesn't explode!

They want to explode every minute now! ”The so-called stars in the sky, except that the stars in the solar system are planets, are basically stars. In the interstellar space, there are very thin matter, mainly composed of gas and dust. Their temperature is about 10-100k, and their density is about 10-24-10-23g / cm3, which is equivalent to 1-10 hydrogen atoms in 1cm3. The distribution of interstellar matter in space is not uniform, usually in pieces, forming a diffuse nebula. 3 / 4 of the mass of matter in the nebula is hydrogen, which is electrically neutral Or ionized state, the rest about? It is helium and a few elements heavier than helium. There are also gaseous compound molecules in some areas of the nebula, such as hydrogen molecules, carbon monoxide molecules, etc. if there are enough substances in the nebula, it is unstable in dynamics. Under the influence of external disturbance, the star cloud will shrink inward and split into smaller masses, after many times of

splitting and shrinking A new star is born when the temperature of the nuclear region increases to the point where hydrogen fusion can be carried out Wuwu Wuwu ”a pair of hands appeared in time from the back, a hand covered the mouth of Yubi youth No. 1, dragged him to the back, and Yubi youth No. 4 said flatteringly:” don't be angry, don't be angry! Our eldest brother is a bookworm. If you encounter any problems, you will like to be serious. We are here to return the heat preservation barrel. Continue! The stars in the sky are very beautiful and suitable for love! ” Then No. 4, chubby, dragged No. 1 back and scolded him: ”do you know why you are a graduate student or a single dog? Whose girl is listening to you beep these? Who will study the formation of celestial bodies when they fall in love... ”
