Key Stage 4
Meaning
The Universe is everything that exists.
About the Universe
- The Universe has over 200 billion galaxies.
- The Universe is around 13.7 billion Earth years old.
- Everything that has ever happened and ever will happen will all take place in the Universe.
Origin of the Universe
Big Bang Theory
- The current prevailing theory for the origin the modern universe is the Big Bang Theory backed by evidence which shows all the observed galaxies in the universe must have all begun at one small point in space.
Evidence:
Redshift - Redshift shows that all of the 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 Stars - There have not been any stars observed older than 13 billion years.
Future of the Universe
- Current evidence shows the galaxies are accelerating away from us suggesting the universe will continue to expand forever.
- Some scientists used to believe the universe would end with all the matter falling back together. The theory was called The Big Crunch but it seems unlikely to be true due to the counter evidence.
