The temperature of the universe has cooled over time.
The evidence of universe expansion that supports the Big Bang Theory is: The temperature of the universe has cooled over time.
The evidence of universe expansion that supports the Big Bang Theory is that the temperature of the universe has cooled over time. This is known as the cosmic microwave background radiation.
To understand how this evidence supports the Big Bang Theory, we need to look into the concept of the Big Bang. According to the Big Bang Theory, the universe originated from a single, extremely hot and dense point around 13.8 billion years ago. As the universe expanded, it started cooling down.
When the universe was in its early stages, it was so hot that it was filled with a plasma of particles. As the universe expanded and cooled over time, this plasma gradually transformed into neutral atoms. At this point, the universe became transparent to radiation, allowing light to travel freely.
The cosmic microwave background radiation is the residual heat that was left over from the early universe and is a remnant of the Big Bang. It is a faint radiation that permeates the entire universe and is uniform in all directions. This radiation corresponds to the cooling process of the universe.
By measuring and studying the cosmic microwave background radiation, scientists have found that it corresponds to a temperature of about 2.7 Kelvin (-270.45 degrees Celsius or -454.81 degrees Fahrenheit). This low temperature provides evidence for the expansion of the universe and supports the Big Bang Theory.
So, to answer the question, the evidence of universe expansion that supports the Big Bang Theory is that the temperature of the universe has cooled over time.
