false

Explanation:

The 3K cosmic microwave background radiation (CMB) is a faint, uniform microwave radiation filling the universe, corresponding to a temperature of approximately 2.725 K (often rounded to 3K). It is a direct remnant of the hot, dense early universe predicted by the Big Bang Theory, making it one of the key pieces of evidence supporting the theory.

True
