An enormous amount of weak cosmic background radiation has been detected in the universe.
The temperature of the universe is decreasing
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 temperature of the universe is increasing
The universe is undergoing a cycle of contraction and expansion
An enormous amount of weak cosmic background radiation has been detected in the universe.
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 supporting 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 three correct answers that provide evidence of universe expansion and support the Big Bang theory are:
1. An enormous amount of weak cosmic background radiation has been detected in the universe. This is known as the Cosmic Microwave Background (CMB) radiation. It is a remnant of the early stages of the universe and is uniformly distributed in all directions. The detection of the CMB provides strong evidence for the Big Bang theory.
2. Galaxies are moving away from each other. This observation is known as the redshift of light from distant galaxies. It indicates that the universe is expanding, as the space between galaxies is stretching. The observation of redshift supports the idea that the universe had a beginning with the Big Bang.
3. The temperature of the universe is decreasing. As the universe expands, the energy in it gets diluted, leading to a cooling effect. This is consistent with the predictions of the Big Bang theory, which suggests that the universe started out extremely hot and has been cooling down ever since.
To answer this question, it is important to have a basic understanding of the Big Bang theory and the evidence that supports it. The first answer can be obtained by knowing about the discovery of the CMB radiation, while the second answer requires knowledge of the redshift of light. The third answer is obtained by understanding the concept of the universe's expansion and its effect on temperature.
