Question

What is our universe called?

Answer 1

Universe:

1. The universe is enormous, and it continues to expand. However, astronomers disagree on how quickly it is expanding.
2. For the past 60 years, evidence for the expansion of the universe has been accumulating.
3. The redshift is the first significant clue.
4. Some wavelengths of light are more strongly emitted or absorbed by a galaxy than others. As the galaxy recedes from us, these emission and absorption feature shift to longer wavelengths, becoming redder as the recession velocity increases. This is referred to as redshift.

Therefore, our universe is called the cosmos.
