The temperature of the universe has cooled and warmed repeatedly over time. The temperature of the universe has cooled over time. The temperature of the universe has cooled over time. The temperature of the universe has warmed over time. The temperature of the universe has warmed over time. The temperature of the universe is the same as it was at the time of the Big Bang.
The temperature of the universe has cooled over time.
Which provides evidence of universe expansion that supports the Big Bang Theory? Select the three correct answers.(2 points) Responses The temperature of the universe is decreasing. The temperature of the universe is decreasing. An enormous amount of weak cosmic background radiation has been detected in the universe. An enormous amount of weak cosmic background radiation has been detected in the universe. The universe is undergoing a cycle of contraction and expansion. The universe is undergoing a cycle of contraction and expansion. The temperature of the universe is increasing. The temperature of the universe is increasing. Galaxies are moving away from each other. Galaxies are moving away from each other. The temperature of Cosmic Microwave Background radiation varies widely from one part of the universe to another.
The three correct answers that provide evidence of universe expansion that supports the Big Bang Theory are:
1) An enormous amount of weak cosmic background radiation has been detected in the universe.
2) Galaxies are moving away from each other.
3) The temperature of the universe is decreasing.
The sentence "Galaxies are moving away from each other" provides evidence of universe expansion that supports the Big Bang Theory.
The sentence that provides evidence of universe expansion that supports the Big Bang Theory is: "Galaxies are moving away from each other." This statement reflects the idea of cosmic expansion as proposed by the Big Bang Theory.
To understand why this sentence provides evidence for universe expansion, you can consider the concept of redshift. Redshift refers to the phenomenon in which light from distant objects, such as galaxies, appears shifted towards longer wavelengths. This shift is caused by the stretching of space as the universe expands.
Scientists have observed that galaxies located farther away from us show greater redshifts, indicating that they are moving away at faster speeds. This observation supports the notion that the universe is expanding, with galaxies moving apart from each other. Thus, the sentence "Galaxies are moving away from each other" provides evidence for universe expansion as predicted by the Big Bang Theory.
