→Origin of the Universe
Old [[Star]]s - There have not been any [[star]]s [[observe]]d older than 13 billion years.
====Steady State Theory====
: A previous, but not widely accepted, [[Scientific Theory|theory]] was the [[Steady State Theory]] which suggested the [[universe]] never had a beginning. It was always here. It was suggested that as the [[galaxy|galaxies]] move apart from one another, new [[galaxy|galaxies]] would come into existence to fill the gaps.
Evidence:
[[Redshift]] - [[Redshift]] shows that all of the [[galaxy|galaxies]] are moving away from each other at very high [[speed]].
===Future of the Universe===
: Current [[evidence]] shows the [[galaxy|galaxies]] are accelerating away from us suggesting the [[universe]] will continue to expand forever.
: Some [[scientist]]s used to believe the [[universe]] would end with all the [[matter]] falling back together. The [[Scientific Theory|theory]] was called [[The Big Crunch]] but it seems unlikely to be true due to the counter [[evidence]].
