The correct answer is: Its temperature is uniform.
The correct response is: Its temperature fluctuates greatly.
Cosmic Microwave Background (CMB) radiation is considered a remnant of the Big Bang because its temperature fluctuations are consistent with the predictions of the Big Bang theory. The CMB radiation is almost uniform, but it does have small temperature fluctuations across the sky. These fluctuations provide valuable information about the early universe and the formation of galaxies and large-scale structures. This evidence supports the idea that CMB radiation originated from the hot, dense state of the early universe during the Big Bang.
The evidence that supports the idea that Cosmic Microwave Background (CMB) radiation is a remnant of the Big Bang is that its temperature is uniform.
To get this answer, we can examine the characteristics of the CMB radiation and compare them to the predictions of the Big Bang theory. The Big Bang theory proposes that the universe originated from a high-density, high-temperature state and has been expanding ever since. As the universe expanded, it cooled down. According to this theory, the CMB radiation is the afterglow of this initial hot and dense state, now cooled down to a temperature of about 2.7 Kelvin.
The fact that the CMB radiation has a uniform temperature is significant. If the universe originated from a single point, as suggested by the Big Bang theory, then the CMB radiation would be expected to have a uniform temperature as it evenly distributed throughout space. This uniformity is exactly what has been observed in numerous measurements of the CMB radiation, confirming the predictions of the Big Bang theory.
On the other hand, if the CMB radiation had a fluctuating temperature, it would suggest that the universe did not originate from a single point but rather through other processes not predicted by the Big Bang theory. However, the observed uniform temperature of the CMB strongly supports the idea that it is indeed a remnant of the Big Bang.
