What triggered the cyclic model of the origin of the universe? (1 point)

Question

Some scientists argue that the planets do not orbit in circles around the sun.
Some scientists found that the amount of radiation in space is not consistent with an explosion.
Some scientists think that the universe will not keep expanding forever.
Some scientists began to use telescopes and mathematics to study the universe.

Answer 1

The correct answer is: Some scientists think that the universe will not keep expanding forever.

The cyclic model of the universe suggests that the universe undergoes infinite cycles of expansion and contraction, which is brought into question by the idea that the universe may not expand indefinitely. This leads to the exploration of models that incorporate a "big crunch" followed by a "big bang," resulting in a cyclic nature.
