Answer:
Option 1
It provides evidence of universe expansion
Explanation:
The Big Bang Theory actually explains the universe as originating from a single point, which expanded as billions of years went by.
The background radiation supports this theory in the sense that if the universe is expanding, this means that the universe is cooling and continuously losing heat, which results in background radiation
The weak background radiation supports the big bang theory because it provides evidence of UNIVERSE EXPANSION (Option 1).
The Big Bang theory is a prevailing cosmological scientific theory to explain how the Universe began and its subsequent evolution.
According to the Big Bang theory, the cosmic microwave background is electromagnetic radiation considered as a remnant from the early Universe.
The Big Bang theory states that the Universe is expanding, causing it to cool because energy is more diluted in space.
In consequence, it has been proposed that the cosmic microwave background is a remnant heat leftover from the Big Bang.
In conclusion, the weak background radiation supports the big bang theory because it provides evidence of UNIVERSE EXPANSION (Option 1).
