Weak radiation that is left over from early, hot stages of expansion of universe
Singularity
A point of infinite density that contained all of the matter, space, and time of the universe
Hydrogen
Main element formed in the Big Bang
Red Shift
Shift toward longer wavelengths of spectral lines emitted by a celestial object. Caused by object moving away from earth, important piece of evidence for Big Bang Theory
Doppler Effect
The change in the length of wavelengths when the source of the waves or the observer moves
Big Bang Theory
Theory the universe began as a small point that expanded rapidly about 13.7 billion years ago
