select the correct answer. which fact represents evidence for the big - bang theory? a. every object located in the universe emits radiation. b. the mass that makes up the universe consists of 25% helium. c. the sun around which earth revolves is not the biggest star in the universe. d. human eyes cannot perceive all forms of electromagnetic radiation.
Answer
Brief Explanations:
The cosmic - microwave background radiation, which is a form of radiation emitted by objects in the universe, is one of the key pieces of evidence for the Big - Bang theory. The Big - Bang theory predicts the existence of this residual radiation from the early universe. Option B about the helium mass fraction is also related but not as direct as the radiation evidence. Option C is about the size of the Sun relative to other stars and Option D is about human perception of electromagnetic radiation, both of which are not evidence for the Big - Bang theory.
Answer:
A. Every object located in the universe emits radiation.
