Question

how does cosmic microwave background radiation support the big bang theory? microwaves are found everywhere in the universe. microwaves are useful in our everyday lives microwaves occurred at the time of the big bang

Explanation:

To determine which statement supports the Big Bang Theory with Cosmic Microwave Background (CMB) Radiation:

• The first option ("Microwaves are found everywhere in the universe") aligns with CMB’s nature: CMB is a uniform microwave radiation permeating the universe, leftover from the Big Bang’s early stages. This supports the theory’s prediction of residual radiation from the universe’s hot, dense origin.
• The second option ("Microwaves are useful in our everyday lives") refers to human - made microwave applications (e.g., ovens), irrelevant to the Big Bang.
• The third option ("Microwaves occurred at the time of the Big Bang") is inaccurate; CMB is radiation from the Big Bang’s aftermath (when the universe cooled enough for light to travel freely), not that microwaves “occurred” during the Big Bang event itself.

Answer:

The correct statement is: Microwaves are found everywhere in the universe.
