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. The discovery of cosmic microwave background radiation, which is electromagnetic radiation left over from the early stages of the universe, provides strong evidence for the Big Bang Theory. This radiation is considered a remnant of the extremely hot and dense state of the early universe.
To get this answer, one can look for scientific studies and experiments related to cosmic microwave background radiation detection, such as the research done by the COBE (Cosmic Background Explorer) and Planck missions.
2. The temperature of the universe is decreasing. According to the Big Bang Theory, the universe has been expanding and cooling down since its initial hot and dense state. The observed decrease in the average temperature of the universe over time supports this idea.
To find evidence for this answer, scientific sources such as astrophysical observations and cosmological studies that measure and analyze the temperature of the universe would be relevant.
3. Galaxies are moving away from each other. One of the key pieces of evidence supporting the Big Bang Theory is the observation of galactic redshift, which indicates that galaxies are moving away from each other. This discovery is consistent with the idea that the universe is rapidly expanding as a result of the initial Big Bang event.
To obtain evidence for this answer, one can look for astronomical observations, such as measurements of redshift in distant galaxies, as well as studies on the expansion of the universe and the movement of celestial objects.
The correct answers are:
1. An enormous amount of weak cosmic background radiation has been detected in the universe.
2. The temperature of the universe is decreasing.
3. Galaxies are moving away from each other.
