| ARTICLES RELATED TO baryogenesis | | | | |  baryogenesis: Encyclopedia II - Big Bang - Observational evidenceIt is generally stated that there are three observational pillars that support the Big Bang theory of cosmology. These are the Hubble-type expansion seen in the redshifts of galaxies, the detailed measurements of the cosmic microwave background, and the abundance of light elements. (See Big Bang nucleosynthesis.) Additionally, the observed correlation function of large-scale structure of the cosmos fits well with standard Big Bang theory.

| | | | | baryogenesis: Encyclopedia II - Big Bang - History The Big Bang theory developed from observations 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. In 1927, the Belgian Catholic priest Georges Lemaître independently derived the Friedmann-Lemaître-Robertson-Walker equations and proposed, on the basis of the recession of spiral nebulae, that the Universe began with the "explosion" of a "primeval atom"†...

| | | | | baryogenesis: Encyclopedia II - Big Bang - The future according to the Big Bang theory Before observations of dark energy, cosmologists considered two scenarios for the future of the Universe. If the mass density of the universe is above the critical density, then the Universe would reach a maximum size and then begin to collapse. It would become denser and hotter again, ending with a state that was similar to that in which it started—a Big Crunch. Alternatively, if the density in the Universe is equal to or below the critical density, the expansion would slow down, but never stop. Star formation would cease as the Universe ...

| | | | | baryogenesis: Encyclopedia II - Big Bang - Speculative physics beyond the Big Bang While the Big Bang model is well established in cosmology, it is likely to be refined in the future. Little is known about the earliest Universe, when inflation is hypothesized to have occurred. There may also be parts of the Universe well beyond what can be observed in principle. In the case of inflation this is required: exponential expansion has pushed large regions of space beyond our observable horizon. It may be possible to deduce what happened when we better understand physics at very high energy scales. Sp ...
