Our podcast is about important things from our past about our universe, the start of our universe. The first important thing is redshift, it has 2 different colors which are blue and red. When the wavelength is long is red, when it's short it's blue. This helps with the big bang theory. In space, there is a small radiation portion that remained from our old universe which is known as cosmic background radiation. Universe expansion is the reason our planets and space are here, when the big bang was finished it was expanding its lengths to make more space. This all connects to the big bang theory, with the theory’s of, our universe started when there was an explosion and still believed to be expanding. The other reason it supports the big bang was redshift. Since the universe is expanding today the wavelengths are expanding. And the last reason is because of cosmic background radiation. Small particles from our old universe helped us figure out what really was our old universe.
