  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.
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 effect on cosmology of the dark energy that these models describe is given by the dark energy's equation of state, which varies depending upon the theory.

The existence of our galaxy, the Milky Way, as a separate group of stars was only proven in the 20th century, along with the existence of "external" galaxies, and soon after, the expansion of the universe seen in the recession of most galaxies from us.
Cosmology, a discipline that has a large intersection with astronomy, made huge advances during the 20th century, with the model of the hot big bang heavily supported by the evidence provided by astronomy and physics, such as the cosmic microwave background radiation, Hubble's Law and cosmological abundances of elements.

The Bible contains a number of statements on the position of the earth in the universe and the nature of the stars and planets, most of which are poetic rather than literal; see Biblical cosmology.
In 500 AD, Aryabhata presented a mathematical system that took the earth to spin on its axis and considered the motions of the planets with respect to the sun.

 Dark energy - Wikipedia, the free encyclopedia
In cosmology, dark energy is a hypothetical form of energy which permeates all of space and has strong negative pressure.
These observations are explained by postulating a kind of energy with negative pressure (see equation of state (cosmology) for a mathematical explanation): dark energy.
Other ideas for dark energy have come from string theory, brane cosmology and the holographic principle, but have not yet proved as compelling as quintessence and the cosmological constant.

In cosmology, the Big Bang theory is the prevailing scientific theory about the early development and shape of the universe.
Einstein's theory of general relativity developed during this time had the result that the universe could not remain static, a result that he himself considered wrong, and which he attempted to fix by adding a cosmological constant which did not fix the problem.
Huge advances in Big Bang cosmology were made in the late 1990s and the early 21st century as a result of major advances in telescope technology in combination with large amounts of satellite data such as from COBE and WMAP.

In physical cosmology, the Big Bang is the scientific theory that the universe emerged from an enormously dense and hot state about 13.7 billion years ago.

Dark energy in its simplest formation takes the form of a cosmological constant term in Einstein's field equations of general relativity, but its composition is unknown and, more generally, the details of its equation of state and relationship with the standard model of particle physics continue to be investigated both observationally and theoretically.

While the first division is applicable to both observers and theorist, the second one applies only to observers (and imperfectly), as theorists try to use all the information available, in all wavelength, and observer often observe in more than one region of the spectrum.

Bruno's cosmology is marked by infinitude, homogeneity, and isotropy, with planetary systems distributed evenly throughout.
This animism (and a corresponding disdain for mathematics as a means to understanding) is the most dramatic respect in which Bruno's cosmology differs from what today passes for a common-sense picture of the universe.

In the classical Doppler effect, the frequency of the source is not modified, but the recessional motion causes the illusion of a lower frequency.
An effect very similar to the Doppler effect is caused by the expansion of space predicted by the current models of physical cosmology.
Alternative hypotheses (for example, tired light and other suggestions from nonstandard cosmologies) are not generally considered plausible.
