Its temperature fluctuates greatly.

Answer 1

The evidence that supports the idea that Cosmic Microwave Background (CMB) radiation is a remnant of the Big Bang includes:

1. Its temperature is uniform. - The CMB radiation is remarkably uniform across the sky, with only slight variations in temperature. This uniformity supports the idea that it originated from a hot, dense state of the universe shortly after the Big Bang.

2. Its mass is uniform. - While the CMB itself is not a mass but a form of radiation, the uniformity in the distribution of the CMB across the universe suggests that it has a consistent origin related to the early universe.

In summary, the most relevant points are its uniform temperature (and the concept of uniformity in the CMB's properties) as evidence supporting the Big Bang theory.
