Relativistically refers to the theory of relativity, but there are many synonyms that can be used to convey a similar meaning. For example, the word relativistic can be replaced with words such as comparative, subjective, and perception-based. The phrase "in relation to" can also be used as a substitute. Alternatively, phrases such as "from a relative standpoint" and "according to one's perspective" can be used as synonyms. Other options include phrases such as "with respect to," "in comparison to," and "based on one's frame of reference." All of these alternatives allow for a similar meaning to be conveyed in place of the word "relativistically".
