Big Bang Theory
-Used to think everything in the sky was static / did not change- One small point
-Suddenly exploded into everything we know today
-Proof is that galaxies are moving away from each other at a slower pace
-Universe is still expanding
-The universe has been cooling ever since the Big Bang
Cosmic radiation is another fact supporting the Big Bang Theory. Scientists believe that this radiation is left over from the Big Bang Theory.
The blue shift is when celestial bodies are moving closer to each other creating a faster wavelength, which is closer to the colour blue on the spectrum.
