hat triggered the cyclic model of the origin of the universe?(1 point)
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 began to use telescopes and mathematics to study the universe.
Some scientists think that the universe will not keep expanding forever.
Some scientists began to use telescopes and mathematics to study the universe.
The correct answer is: Some scientists found that the amount of radiation in space is not consistent with an explosion.
To arrive at this answer, you can consider the scientific discoveries made through observations and data analysis. In the mid-20th century, two physicists named Arno Penzias and Robert Wilson observed an unusual form of radiation in the universe known as the Cosmic Microwave Background (CMB).
The CMB is essentially the remnant radiation from the Big Bang, the alleged initial explosion that marked the beginning of the universe. However, Penzias and Wilson discovered that the amount of radiation detected did not match the expected levels for an explosion.
This discovery led to the development of the cyclic model of the origin of the universe. According to this model, the universe goes through a cycle of expansion and contraction, with each cycle preceded by a cosmic "bounce" instead of a singular explosive event. This cyclic model suggests that the universe has existed eternally, undergoing repeated cycles of expansion and contraction.
Therefore, the discovery of inconsistent radiation levels led some scientists to propose the cyclic model as an alternative explanation for the origin of the universe.
The correct answer is:
Some scientists found that the amount of radiation in space is not consistent with an explosion.
