Which is evidence of universe expansion that supports the Big Bang Theory?(1 point) Responses The temperature of the universe is the same as it was at the time of the Big Bang. 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 and warmed repeatedly over time. 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 sentence "The temperature of the universe has cooled over time." provides evidence of universe expansion that supports the Big Bang Theory. According to the Big Bang Theory, the universe started as a hot and dense state and has been expanding and cooling over time. The fact that the temperature of the universe has cooled supports this concept of expansion.
Which provides evidence of universe expansion that supports the Big Bang Theory? Select the three correct answers.(2 points) Responses Galaxies are moving away from each other. Galaxies are moving away from each other. 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 temperature of the universe is increasing. The temperature of the universe is increasing. The temperature of the universe is decreasing. The temperature of the universe is decreasing. The temperature of Cosmic Microwave Background radiation varies widely from one part of the universe to another. The temperature of Cosmic Microwave Background radiation varies widely from one part of the universe to another. The universe is undergoing a cycle of contraction and expansion.
The three sentences that provide evidence of universe expansion that supports the Big Bang Theory are:
1. Galaxies are moving away from each other.
2. An enormous amount of weak cosmic background radiation has been detected in the universe.
3. The temperature of the universe is decreasing.
These pieces of evidence align with the Big Bang Theory, which postulates that the universe originated from a hot and dense state and has been expanding since then. The observed movement of galaxies away from each other, the detection of cosmic background radiation, and the decrease in the temperature of the universe over time all support the idea of universe expansion.
