What is cosmology?


Cosmology is the study of the Universe and its components; stars, planets, galaxies, rocks, dust. Cosmology is the science of the world. Cosmology is a part of Astronomy. Astronomy is the general topic and Cosomology is the specific.

Christian Wolff was the first one who, in 1730, used the word cosmology. There were some different, specific kinds of Cosmology. One is Neolithic Cosmology. 20,000 to 100,000 years ago, people believed that they were always interacting with the Universe. They believed weather, earthquakes and abrupt change in their environment were all part of cosmology, or cosmological. Later on, when people had cultures, myths were made about the Universe's origin. There is also Egyptian/Mesopotamia Cosmology. In Egyptian Cosmology, Egyptians observed astronomically the solar motion over the horizon because the sun god, Ra, considered a very important god. Mythology of Egyptian Cosmology was established by the solstices. A solstice is a time when the sun is at the farthest distance from the celestial equator. The Mesopotamia Cosmology, or the Babylonians, had records of eclipses, the positions of the planets, and when the moon would rise up or would set. Also, the Babylonian astronomers, to predict the movement of planets and the occurrences of eclipses, they created many arithmetic instruments. Finally, there is Greek Cosmology. The Greek believed that the Universe could be shown in math form in science. There were thoughts organized into two groups. One thought was that math was something we discovered, not created, and that nature was functioning through math. Also, the thought suggests that there is a Platonic world, and the physical world covers up the facts of the Platonic world. The other thought was that math was really something from the physical world.

What caused cosmology to start? Who studies cosmology and why?


Cosmology has been around forever! Scientific Cosmology was said to have started with the Ancient Greeks.

Cosmologists study Cosmology.

Cosmologists use different sciences for observing and theory techniques. Physics, Chemistry, and other sciences are also part of Cosmology.

The way that people really started to think about and eventually studied cosmology was when they asked themselves questions like, "What is happening around me?" and "In what way does the universe work?" Cosmology is basically asking these questions.

Who discovered cosmology? (When, Where, How, Why)

Pythagoras thought the world was rotating in 500 BC - 300 BC. He lived in Ancient Greece.

Cosmology was discovered in different civilizations. These are: Babylonian (4000 - 300 B.C.), Egyptian (3400 - 30 B.C.), Greek (2800 B.C. - 3600 A.D.), and Mayan (2000 B.C. - 900 A.D.).

Pythagoras and Plato both affected the first cosmological view of the world. This was created in the fourth century B.C. by the Greek. It claims that the four elements: Air, Earth, Fire, and Water, combined compose the Universe. The two properties of hotness and coldness and dry and wet are form where the four elements come from. Nicolaus Copernicus, an astronomer, believed the sun was the center of the universe. This theory of his was called the heliocentric theory, or heliocentric cosmology. Galileo Galilei, an astronomer, also supported Nicholas about this theory.
