How does the change in the temperature of the universe provide evidence for universe expansion that supports the Big Bang Theory?(1 point) Responses The universe is warming which, according to the Big Bang Theory, is expected to happen as the cosmos accumulates. The universe is warming which, according to the Big Bang Theory, is expected to happen as the cosmos accumulates. The universe is cooling which, according to the Big Bang Theory, is expected to happen as the cosmos disperses. The universe is cooling which, according to the Big Bang Theory, is expected to happen as the cosmos disperses. The universe is cooling which, according to the Big Bang Theory, is expected to happen as the cosmos accumulates. The universe is cooling which, according to the Big Bang Theory, is expected to happen as the cosmos accumulates. The universe is warming which, according to the Big Bang Theory, is expected to happen as the cosmos disperses.
The universe is cooling which, according to the Big Bang Theory, is expected to happen as the cosmos disperses.
This is because the Big Bang Theory states that the universe started from a hot and dense state and has been expanding and cooling ever since. As the universe expands, the energy and temperature spread out, resulting in a cooling effect.
The correct response is:
The universe is cooling which, according to the Big Bang Theory, is expected to happen as the cosmos disperses.
The correct response is: The universe is cooling which, according to the Big Bang Theory, is expected to happen as the cosmos disperses.
To understand why the change in temperature of the universe provides evidence for universe expansion and supports the Big Bang Theory, we need to look at the basic concepts behind the theory.
The Big Bang Theory suggests that the universe originated from a singularity, a point of infinite density and temperature, about 13.8 billion years ago. It states that the universe has been expanding ever since.
One of the key predictions of the Big Bang Theory is that as the universe expands, the temperature of the universe should decrease. This is because the radiation and matter in the universe become more spread out as space expands, causing a drop in temperature.
Observations of the cosmic microwave background radiation (CMB) provide strong evidence for the cooling universe. The CMB is the remnant radiation from the early stages of the universe, when it was hot and dense. By studying this radiation, astronomers have found that it has a characteristic black body temperature of around 2.7 Kelvin, or about -270.45 degrees Celsius.
The fact that the CMB radiation has such a low temperature is consistent with the Big Bang Theory's prediction of a cooling universe. It supports the idea that the universe has been expanding and cooling for billions of years, consistent with our current understanding.
Overall, the change in temperature of the universe, specifically the cooling trend, provides evidence for universe expansion and supports the Big Bang Theory.
