The Big Bang, the theoretical start of the universe is a very interesting topic. There are 3 big pieces of evidence of the Big Bang Theory. Redshift and Blueshift, the appearance of red when a galaxy is moving away from us and blue when moving towards us. Cosmic Microwave Background Radiation(CMB), Constant microwaves all the time everywhere in the universe accidentally discovered by a radio receiver. This radio receiver was created by Radio Astronomers Robert Wislon and Arno Penzias and they were shocked when all that it was picking up was microwaves constantly coming from everywhere in the sky. Hydrogen and Helium, the base elements to all elements we know today formed just seconds after the Big Bang. These elements make up 98% of the universe and if they didn’t exist neither would the universe as we know it.
