The Big Bang Theory
Theory
An explanation that ties together many observations and hypotheses. The hypotheses have been tested over time gathering evidence to support the theory
Relation: Cosmic Background Radiation
Background energy can be thought of as the left over energy from the explosion associated with the Big Bang theory. Over time the Universe has expanded causing the left over energy/afterglow to red shift to a low energy level wavelength.
Relation: Hubble's Law
Hubble's Law supports red shift and an expanding Universe. "Rewinding time" using the currents speeds and distances as explained by Hubble's Law returns matter to a single starting point referred to as singularity.
Cosmic Background radiation
Leftover energy from the initial stages of the Big Bang. This temperature was predicted by scientists to be in the microwave energy range of the electromagnetic spectrum.
Relation: Redshift
Most of the galaxies in the Universe are red shifted. This means the Universe is expanding. This is consistent with the Big Bang Theory.
Relation: Theory
The Big Bang Theory explains the formation of the Universe and uses red shift, Hubble's Law and background radiation as evidence.
What information can be obtained from the COBE satellite?
The Cosmic Background Explorer, also referred to as Explorer 66, was a satellite dedicated to cosmology
Hubble's Law
The direct relationship between the distance of galaxies and their speed. Galaxies that are farther away are moving.
What evidence supports The Big Bang Theory?
The theory about the formation of the Universe has several components that occur in a sequence - singularity, explosion, expansion, randomness, building blocks, stars, galaxies, continued expansion. This theory has several layers of supporting evidence including red shift, Hubble's Law, and cosmic background radiation.

Big Bang Theory
The theory that states the universe began with a tremendous explosion 13.7 billion years ago.
Redshift
When looking at an object through a spectroscope that is moving away, the wavelengths shift to the red end of spectrum.
