==Key Stage 4==
===Meaning===
The '''big bang theory''' is a [[Scientific Theory|scientific theory]] which suggests that all the [[matter]] in the [[universe]] once began in the same small point in space.
===About the Big Bang Theory===
: The '''big bang theory''' is the current prevailing [[Scientific Theory|theory]] for the origin the modern [[universe]].
: The [[Big Bang Theory|big bang theory]] is backed by [[evidence]] which shows all the [[observe]]d [[galaxy|galaxies]] in the [[universe]] must have all begun at one small point in [[space]].
====Evidence====
[[Redshift]] - [[Redshift]] shows that all of the [[galaxy|galaxies]] are moving away from each other at very high [[speed]].
[[Cosmic Microwave Background]] - [[Microwave]] [[radiation]] coming from all directions in [[space]] show that at one point the entire [[universe]] was roughly the same [[temperature]] everywhere.
Old [[Star]]s - There have not been any [[star]]s [[observe]]d older than 13 billion years.
