It is about nothing less than the origin and evolution of the universe, the all of everything.
History of the Big Bang The Big Bang theory developed from observations of the structure of the universe and theoretical considerations. Observationally, it was determined that most spiral nebulae were receding from Earth, but those who made the observation weren't aware of the cosmological implications, nor that the supposed nebulae were actually galaxies outside our own Milky Way.
He discovered that, seen from Earth, light from other galaxies is redshifted in direct proportion to their distance from the Earth.
This fact is now known as Hubble's law.

What I don't see in my crystal ball is a laboratory experiment that would close the circle as nuclear physics measurements did for the big bang nucleosynthesis, as the creation of quark/gluon plasma at an accelerator could do for the quark‐soup phase of the early universe, or as the laboratory production of neutralinos could do for particle.
This idea allowed for two main opposing possibilities. The other possibility was Fred Hoyle's steady state model in which new matter would be created as the galaxies moved away from each other. In this model, the universe is roughly the same at any point in time.
Hoyle repeated the term in further broadcasts in earlyas part of a series of five lectures entitled The Nature of Things. The text of each lecture was published in The Listener a week after the broadcast, the first time that the term "big bang" appeared in print.
Some of these alternatives included the Milne model, Richard Tolman's oscillatory universe, and Fritz Zwicky's tired light hypothesis. However, the observational evidence began to support the idea that the universe evolved from a hot dense state. Since the discovery of the cosmic microwave background radiation init has been regarded as the best theory of the origin and evolution of the cosmos.
Virtually all theoretical work in cosmology now involves extensions and refinements to the basic Big Bang theory. Much of the current work in cosmology includes understanding how galaxies form in the context of the Big Bang, understanding what happened at the Big Bang and reconciling observations with the basic theory.
Huge advances in Big Bang cosmology were made in the late s and the early 21st century as a result of major advances in telescope technology in combination with large amounts of satellite data such as that from COBE, the Hubble Space Telescope and WMAP.
Such data have allowed cosmologists to calculate many of the parameters of the Big Bang to a new level of precision and led to the unexpected discovery that the expansion of the universe appears to be accelerating.
Timeline of cosmology  Overview A graphical timeline is available here: Graphical timeline of the Big BangBased on measurements of the expansion of the universe using Type 1a supernovae, measurements of the lumpiness of the cosmic microwave background, and measurements of the correlation function of galaxies, the universe has a calculated age of The early universe was filled homogeneously and isotropically with an incredibly high energy density and concomitantly huge temperatures and pressures.
It expanded and cooled, going through phase transitions analogous to the condensation of steam or freezing of water as it cools, but related to elementary particles. After inflation stopped, the material components of the universe were in the form of a quark-gluon plasma also including all other particles—and perhaps experimentally produced recently as a quark-gluon liquid  in which the constituent particles were all moving relativistically.
As the universe continued growing in size, the temperature dropped. At a certain temperature, by an as-yet-unknown transition called baryogenesis, the quarks and gluons combined into baryons such as protons and neutrons, somehow producing the observed asymmetry between matter and antimatter.
Still lower temperatures led to further symmetry breaking phase transitions that put the forces of physics and elementary particles into their present form. Later, some protons and neutrons combined to form the universe's deuterium and helium nuclei in a process called Big Bang nucleosynthesis.
As the universe cooled, matter gradually stopped moving relativistically and its rest mass energy density came to gravitationally dominate that of radiation.
After aboutyears the electrons and nuclei combined into atoms mostly hydrogen ; hence the radiation decoupled from matter and continued through space largely unimpeded. This relic radiation is the cosmic microwave background.
Over time, the slightly denser regions of the nearly uniformly distributed matter gravitationally attracted nearby matter and thus grew even denser, forming gas clouds, stars, galaxies, and the other astronomical structures observable today.Gluon sample projects.

Nov 17, · Best Answer: I don't believe God made the universe if that makes you feel better, In physical cosmology, the Big Bang is the scientific theory that the universe emerged from a tremendously dense and hot state about billion years ago. The proportionality factor is known as the Hubble 'constant' (in reality it is a function of time, it is constant at a given epoch).
To measure the Hubble constant one needs to measure redshifts and distances. Measuring redshifts is relatively straightforward. May 08, · Update: Can someone give me an intelligent, informative explanation of the Big Bang Theory? I'm interesting in what actually caused the universe to come into being, and if it originated from some super-dense chunk of matter, what caused it to first explode and be put into motion.
