The term "conformal time" is commonly used in cosmology to describe the time coordinate that allows for a uniform expansion of the universe. However, there are several synonyms for this term that can also be used to describe the same concept. One such synonym is "conformal distance," which refers to the distance between two points in space that remains constant as the universe expands. Another synonym for conformal time is "cosmic time," which is the time coordinate used to describe the evolution of the universe as a whole. Finally, "synchronous time" is another synonym that can be used to describe the same concept, referring to the time coordinate that allows for the synchronization of locations in space as the universe expands.
