For your final paper, pick of the three topics below.
1. The formation of solar systems

What is the current scientific explanation of how your topic evolved into its current state? Scientific observations of the formation of solar systems have been concluded that the universe has many different types of solar systems and noted that Our Solar system was formed 4.5 billion years ago. Our solar system consists of the Sun, 8 planets, and 5 dwarf planets and asteroids. Many planets have their own moons. However, not all planets have moons. Based upon what we learned in the astronomy course of how everything has a beginning and an ending. Our solar system got created from the cloud that was the Solar Nebula. All stars exist in island called galaxies, and galaxies contain old and new stars as well of clumps of dust clouds. These clouds mostly contain hydrogen and some heavier metals. However, any elements that is heavier than helium is considered to a metal by Astronomers. The formation of the solar systems started with the idea that a very large cloud of hydrogen gas and dust gets disturbed by something and starts to collapse into its center, the center heats up and becomes a proto-star, the center continues to collapse, under the pull of gravity until it gets hot enough to begin fusing hydrogen into helium and becomes a star on the “main sequence”. It is believe that for a system of planets to form around a star during cloud contraction the cloud must contain heavy elements. When a star ends its life, it explodes in a tremendous phenomenon called a Supernova. A Supernova has so much energy that heavy metals are formed-metals like iron and gold. These elements are form from hydrogen clods so that newer stars will contain more heavy elements in their atmosphere.

The solar nebular has several stages. The inner solar system is mainly filled with comets that loop in from the outer reaches of the solar system on elliptical orbits. Solar formation began billions of years ago, when hydrogen gas and dust formed together to create the sun, rocky planets, other bodies of the solar system. All elements from the universe are created through a process of fusion. Smaller things get combined into larger things and every object in the universe belongs to something else. Left over gas formed and evolved into stellar nebulae. New star gives off solar wind highly charges particles. The moment a star turns on, it stop taking gas-it consumed all of the gas and dust of which it was born. The left over gases and dusts evolved into planets, asteroids, comets, for which our Earth was created from. This process is called an accretion disk, which small grains of material pull of gravity and grows into larger objects.

Many scientists thought that the universe was formed from something that called “Dark matter” which is a part of the universe that does not reflect light. Dark matter is relatively small and produces gravity as well. Without gravity there will not be any structure. Dark matter is what pulls and keep the galaxies together, so they will not cluster together. Space has four dimensions, in order to move through space one must move through time. Many scientist concluded that the universe is forever expanding and there are many theories of how the universe begun, how it will ends. From religious theory, scientific theories to ideological hypothesis theories of how creation begun and how each planets, and the solar systems were evolved.

There were three different types of population stars. Our...
