The way the universe is set up gives strong proof for the Big Bang Theory. Here are some important points that explain why:
Cosmic Microwave Background Radiation (CMBR): This is a type of energy that fills the universe, and it was found in 1965. It has a very low temperature, about 2.7 degrees above absolute zero. The fact that this energy is everywhere supports the idea that the universe started from a very hot and crowded state.
Large-Scale Structure: The way galaxies are arranged looks like a huge web. Studies, like the Sloan Digital Sky Survey, show that galaxies gather in clusters and are linked by long strands. In some areas, there aren’t many galaxies, creating empty spaces. These patterns happened because of how galaxies pulled on each other after the Big Bang.
Redshift of Galaxies: Edwin Hubble found out that galaxies are moving away from us. This is shown by a change in the color (called redshift) of the light they emit. On average, this shift is about . This means the universe is expanding, which fits well with what the Big Bang Theory says.
Abundance of Light Elements: Scientists have models that predict the amounts of simple elements like hydrogen, helium, and lithium that should be in the universe. Observations show that about 75% of what we see is hydrogen and about 25% is helium. This matches closely with what the Big Bang Theory predicts.
All of these points support the idea that the Big Bang Theory is the best explanation for how the universe is made and how it looks today.
