Observations of the cosmic background radiation
show that the universe had a predominantly uniform consistency after inflation, except for a light sprinkling of some regions that were more dense and others that were less dense.
Next to alternatives for the theory of relativity and the stretching of light, scientists have found alternatives for the third pillar of current conventional cosmology, the cosmic background radiation
discovered in 1965.
The Wilkinson Microwave Auisotropy Probe (WMAP), which measures the cosmic background radiation
, is in orbit there.
The Herschel and Planck probes will study infrared radiation and cosmic background radiation
The energetic light pumped out by these stars is thought to have ionized the hydrogen gas in and around the galaxies, creating "ionization bubbles" millions of light-years across that left a lasting, telltale signature in the cosmic background radiation
The alternative models are either general worldviews that explain a host of cosmic phenomena, or more focused theories based on the cosmic background radiation
, the Hubble relationship, or new observations of dark matter and dark energy.
Two upcoming satellite studies of the cosmic background radiation
could yield evidence for or against a fourth neutrino's existence.
The Cosmic Background Radiation
Explorer (COBE) launched in 1989, confirmed the prediction made by the Big Bang theory.
