Question

How can scientists test their ideas about the origin of the universe if they can't physically interact with or study it?

Answer 1

Answer:

The cosmological principle makes assumptions that provide scientific guidelines to enable its study.

Explanation:

Cosmology can be described as the study of the origin of the universe.

Although scientists cannot physically study about the origin of the universe but the cosmological studies help scientists to derive ways which makes it easier to hypothesize about the origin of the universe. There are numerous theories and hypothesis generated for the origin of universe based on the cosmological principle.  The cosmological principle states that universe on the whole is homogeneous and it looks the same at any location.
