Nebular Time

Nebula Time Log Date, 2490 We are passing the new system Plutonomy through Warp I was told that a new nebula was formed on the sixth planet. They said that valuable plasma gas is inside. My plan is to be the first to collect everything and sell it so that I can stop wandering in outer space. On the record day, two days after 2492, my co-pilot and I have heard that there is always a match that will be the first match. We are in a leadership position and should not encounter problems. I also decided to buy new food on the ship.

The earth is formed by debris around the protoplanetary disk of the sun. There is no life. The temperature is very high, volcanic activity is frequent, the environment is bad. The atmosphere is the nebula. Possible initial sea or liquid water. The moon was formed at this time, probably because the original planet collided with the earth. Eukaryotes are more complex forms of life that contain certain multicellular organisms. Bacteria produce oxygen and shape the third and the present atmosphere of the Earth 's atmosphere. At this point plants, late animals, and possibly early forms of fungi are formed. In the early and late stages of this era, you may have experienced the "snowball earth" period. There, the temperatures of all the Earths have fallen below 0 degrees. Early continents of Colombia, Rodinia and Panicia may be formed at this time

Recently, there are things that return to Laplace 's nebulae hypothesis, astronomers now accept the sun - nebula disk model (SNDM) or the solar nebula model which is a modern variant of Laplace' s theory. This new model was originally developed by Soviet astronomer Victor Safronov, whose work was "evolution of primitive planetary clouds and formation of the earth and the planet" (Israel's Science Translation Project). It is translated into English. Safronov's hypothesis explains in more detail that George Wetheril discovered that Jupiter's original planet might have its own disk, and the disk formed by the satellite as a whole has a solar system It is similar to. Astronomers now believe that the disk model of the solar system nebula explains not only the formation of the planet in our solar system but also other solar systems.

The Laplacian Nebula model was widely accepted in the 19th century, but later encountered many problems. The main problem is the angular momentum distribution between the sun and the planet. The Laplacian Nebula model can not explain why the planet has 99% angular momentum. Therefore, Laplace's theory of planet formation was almost abandoned in the beginning of the 20th century, and various alternative theories were proposed, but none of them succeeded so much. Recently, there are things that return to Laplace 's nebulae hypothesis, astronomers now accept the sun - nebula disk model (SNDM) or the solar nebula model which is a modern variant of Laplace' s theory. The new model was originally developed by Soviet astronomer Victor Safronov, which was translated as "Evolution of the original planetary cloud and formation of the earth and planet" (scientific translation program of Israel).
