Question
Patterns of emission or absorption lines in spectra can uniquely identify individual atomic elements. Explain how positive identification of atomic elements can be used as one way of testing the validity of the cosmological principle.
Step 1
The cosmological principle states that on a large scale, the universe is homogeneous and isotropic. This means that the universe is the same everywhere and in every direction. This implies that the composition and physical laws of the universe should be the same Show more…
