The Big Bang Theory

The big bang is an idea of how the universe was born We can not be 100% certain this is what happened. There is evidence which supports this idea.

Spectra Each element emits certain colours of light when they glow This is how neon lights work By looking at sun light we can work out what elements are in the sun.

Red Shift Objects moving away from us appear red This is because when an object emitting light moves very fast the frequency we see changes It’s just like an ambulance driving past you All the galaxies we see are red shifted

Cosmic Microwave Background This is the best evidence for the big bang. It is like an echo of the big bang itself.
