The big bang theory can be said to be the best explanation on how the universe started. Most of what we have understood from the big bang theorey comes from mathematical models and formulas.
Only 5 percent of the universe is made up of matters such as the planates, galaxies, and stars.
There are three main pieces of evidence of the big bang theory, they are:
1. Redshift of light as seen from other galaxies
2. Cosmic background radiation
3. Types of element
From the evidence above, we can see that the best evidence for the big bang theory from the provided observations is:
The redshift seen in light from other galaxies.
ANSWER:
D. The redshift seen in light from other galaxies
