What is cosmology?
cosmology is the study of the universe and the place of mankind in it. In the last few hundred years, cosmology has been dominated by physics and astrophysics, which was primarily based on religion. Religion and mythology, which seeks to give humanity the answer to "big questions", offered various answers to the origin of the universe and its arrangement since prehistoric times, but these explanations are replaced by contemporary scientific observations and theories.
However, one should not assume that the current scientific concept of cosmology is correct. Although the general picture has remained the same since the 1920s, specifics are often revised on the basis of new observations and theories. Most remarkably in the history of cosmology, in 1964 was detected space microwave background.G. This happened approximately 13.7 billion years ago. Starting with a singularity with zero volume and a huge matter, the universe was born. Not only was the matter released into space, but the space itself was created by a large bang. Asking about the talk show “What came in front of the velWhom Bang ”, legendary physicist Stephen Hawking replied," What lies north of the North Pole? " Which suggests that the question was not meaningless. However, some physicists consider it likely that our universe is the child universe of the former parent space.
Our current observable universe is estimated to be about 90 billion light years. However, this is only an observable universe and the entire universe can be much larger or even endless. Most cosmology physicists also claim that the universe is just one of many built into a larger multi -ers.
Recently, the idea of anthropy has gained a currency in cosmology. Anthropics refers to the observer's distortion. Most obviously we find ourselves in a universe capable of maintaining life. Physicists made thought experiments where basic physical constants were modified by small increments, and concluded that many of these possible sets of physical lawwould exclude the creation of stable planets or other requirements for life. Rather than indicating that the universe was tuned by a deity, this suggests that our universe is probably one of the huge set of lifeless.
