Responses
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.
Galaxies are moving away from each other.
An enormous amount of weak cosmic background radiation has been detected in the universe.
The temperature of the universe is decreasing.
The temperature of the universe is increasing.
The three correct answers 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 Cosmic Microwave Background radiation varies widely from one part of the universe to another.
The three correct answers that provide evidence of universe expansion supporting the Big Bang Theory are:

The three correct answers that provide evidence of universe expansion supporting the Big Bang Theory are:
1. Galaxies are moving away from each other: This observation is known as the redshift of galaxies. By studying the light from distant galaxies, astronomers have found that the majority of galaxies are moving away from us, indicating that the universe is expanding.
2. The temperature of cosmic microwave background radiation varies widely from one part of the universe to another: The discovery of cosmic microwave background radiation, which is leftover radiation from the early stages of the universe, provides strong evidence for the Big Bang Theory. The observed variation in temperature across the universe supports the idea that the universe was once much smaller and hotter before expanding.
3. An enormous amount of weak cosmic background radiation has been detected in the universe: The detection of cosmic background radiation supports the Big Bang Theory. This radiation is considered a remnant of the initial explosion that occurred during the Big Bang. The fact that this radiation is found throughout the universe further confirms its expansion and the theory itself.
