Primeval Nebular Theory

This theory is the theory that the solar and stellar systems were developed from a primeval nebula. A nebula is a cloud of gas and dust in outer space. A primeval is standing for the earliest ages in the history of the world. This means Primeval nebula means a cloud of gas and dust in outer space a long time ago. It was how people think the galaxy was created. This is saying that the universe was always there. The galaxy was created. Then all the stars and planets were created. They were all made from small clouds of dust and gas in space. The nebular hypothesis is the most widely used theory for the formation of the Solar System. It suggests that the Solar System was formed of nebulous material. It was during the 16th and 18th centuries, …show more content…
As the regions pulled in more things, the momentum caused it to rotate, the pressure caused it to become warm. Most of the things finished up as a ball at the middle while the rest of the things flattened into a wavy circle that circled around it. While the ball at the middle formed the Sun, the rest of the things would turn into a disc. The planets formed by the speed from this disc, in which dust and gas gravitated together and joined together to form ever larger bodies. Due to boiling points, only some materials could exist in a solid form closer to the Sun, and they would soon form the inner planets. Because elements only made a very small fraction of the sun, the inner planets could not grow to be that big. Differently, the giant planets formed on the points between the orbits of Mars and Jupiter where material is cold enough for icy compounds to remain solid. The ices that created many of the planets were more common than the metals and materials that formed the inner planets, letting them grow big enough to take large atmospheres of hydrogen and helium to form something. Leftover space trash that never becomes planets in regions such as the Asteroid Belt, and Kuiper
