At one time, most people believed that the universe was static, meaning it did not change. when larger and better telescopes were invented in the early 1900s, however, it was discovered that light from objects in space shifted toward longer wavelengths. scientists concluded that only an expanding universe could explain this shift. which of the following statements is supported by this example? a. the theory of the expanding universe cannot change, even if new evidence arises. b. scientific knowledge can change when new evidence or interpretations arise. c. the principle of the expanding universe is a scientific law. d. once a scientific theory has been accepted, it can never change.

The correct answer is option B, Scientific knowledge can change when new evidence or interpretations arise.

Explanation:

The logical explanation to any scientific theory/law keeps on changing. This is so because the first logical explanation to any scientific theory was the best possible explanation to it available at that time with the limited resources and was accepted by the majority of peers. But with the advancement in technology some new theories may come forward.  for example – Earlier it was found that atom in the smallest unit of matter , but with the advancement in high scale microscope it was found that even atom is made of smaller particles like electron, proton etc. Thus the scientific theories/laws  get affected by new researches.
