Which term is synonymous with the entire celestial cosmos?

• A. Transit
• B. Transmit
• C. Universe
• D. Yearly (annually)

Answer: (C)

Think about the scope of everything that exists in space and time. The term that captures all of that—the entire celestial cosmos—is the universe. It includes galaxies, stars, planets, gas, dust, and the vast empty space in between, all together as one system. In astronomy, universes is the standard label for this whole expanse, so it fits as the synonym for the entire cosmos. The other options miss the idea: transit refers to moving across a surface, such as a planet crossing in front of a star; transmit means to send something from one place to another; yearly describes a time interval of one year. So the universe is the best choice.
