Which provides evidence of universe expansion that supports the Big Bang Theory? Select the three correct answers. (2 points)
The universe is undergoing a cycle of contraction and expansion
000 Galaxies are moving away from each other.
The temperature of Cosmic Microwave Background radiation varies widely from one part of the universe to another.
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
- 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.
To determine which provides evidence of universe expansion that supports the Big Bang Theory, we need to analyze the options provided.
1. The universe is undergoing a cycle of contraction and expansion: This option does not support the Big Bang Theory, as it suggests a cyclic model where expansion is followed by contraction, rather than a single initial Big Bang event leading to expansion.
2. 000 Galaxies are moving away from each other: This option supports the Big Bang Theory. According to this theory, the universe started from a singular point and has been expanding ever since. Galaxies moving away from each other provide evidence for this expansion.
3. The temperature of Cosmic Microwave Background radiation varies widely from one part of the universe to another: This option supports the Big Bang Theory. The cosmic microwave background radiation is the remnant radiation from the early stages of the universe. The fact that its temperature varies across different regions indicates the expansion and cooling of the universe.
4. An enormous amount of weak cosmic background radiation has been detected in the universe: This option supports the Big Bang Theory. The detection of cosmic background radiation itself is evidence for the idea that the universe originated from a hot, dense, and expanding state.
5. The temperature of the universe is decreasing: This option supports the Big Bang Theory. One of the predictions of the theory is that the universe has been cooling down since its initial hot and dense state due to its expansion.
6. The temperature of the universe is increasing: This option contradicts the Big Bang Theory. The theory suggests that the universe is expanding and gradually cooling down, not getting hotter.
Based on the explanations provided, the three correct answers that support the Big Bang Theory and the expansion of the universe are:
- 000 Galaxies are moving away from each other.
- The temperature of Cosmic Microwave Background radiation varies widely from one part of the universe to another.
- An enormous amount of weak cosmic background radiation has been detected in the universe.
The three correct answers that provide evidence of universe expansion in support of the Big Bang Theory are:
1. Galaxies are moving away from each other.
2. The temperature of Cosmic Microwave Background radiation varies widely from one part of the universe to another.
3. An enormous amount of weak cosmic background radiation has been detected in the universe.
