  Cosmology - Wikipedia, the free encyclopedia
Cosmology is often an important aspect of the origin beliefs of religions and mythologies that seek to explain the existence and nature of the reality.
Modern scientific cosmology is usually considered to have begun in 1917 with Albert Einstein's publication of his final modification of general relativity in the paper "Cosmological Considerations of the General Theory of Relativity," (although this paper was not widely available outside of Germany until end of World War I).
Thus the big bang theory was proposed by the Belgian priest Georges Lemaître in 1927 and rapidly confirmed by Edwin Hubble's discovery of the red shift in 1929 and later by the discovery of the cosmic microwave background radiation by Arno Penzias and Robert Woodrow Wilson in 1964.

 Physical cosmology - Wikipedia, the free encyclopedia
Physical cosmology, as a branch of astrophysics, is the study of the large-scale structure of the universe and is concerned with fundamental questions about its formation and evolution.
Physical cosmology, as it is now understood, began with the twentieth century development of Albert Einstein's theory of general relativity and better astronomical observations of extremely distant objects.
Cosmology is unusual in physics for drawing heavily on the work of particle physicists' experiments, and research into phenomenology and even string theory; from astrophysicists; from general relativity research; and from plasma physics.

The cosmology of the ancients and especially of Aristotle was simply a branch of physics.
Nevertheless, cosmology must borrow, and borrow largely, from the data of science, since the causes which it studies are not directly perceptible; they can be known only through phenomena which are their more or less faithful manifestations.
The Monist theory is that all beings in the world are but one and the same necessary and eternal substance having within itself the sufficient reason of its existence; while the seeming diversity of things and their attributes, are but the various manifestations and evolutions of this single substance.

 History of Cosmology
Cosmology is the study of the Universe and its components, how it formed, how its has evolved and what is its future.
Modern cosmology is on the borderland between science and philosophy, close to philosophy because it asks fundamental questions about the Universe, close to science since it looks for answers in the form of empirical understanding by observation and rational explanation.
The geocentric cosmology becomes the first of many anthropocentric universes, ones where humankind's special nature in the animal world leads to the idea that the Universe is designed for us, or by us.

 Cosmology and Culture
Modern cosmology is now undergoing a foundation-building revolution as it seeks a verifiable description of the nature and origin of the universe.
Anthropologists tell us that in virtually all traditional cultures, a cosmology is what gives its members their fundamental sense of where they come from, who they are, and what their personal role in life's larger picture might be.
Cosmology is whatever picture of the universe a culture agrees on.

The absence of a cosmology was as inconceivable as the absence of language.
But a cosmology that does not account for human beings or enlighten us about the role we may play in the universe will never satisfy the demand for a functional cosmology that religions have been trying to satisfy for millennia.

 The New Cosmology
Modern cosmology is based on Einstein's fundamental theory of gravity: the theory of general relativity.
The Standard Model of cosmology, when combined with atomic and nuclear physics, makes two interesting predictions about the early history of the cosmos that were confirmed by observations and led to the strong belief that the above picture of our expanding Universe was valid.
The very lightest nuclei, those of hydrogen, helium, lithium and beryllium and their isotopes, which compose the first four elements of the periodic table, should have been generated when the Universe was one to three minutes old.
