the İmmeasureable problem for earth rotatin feat

[Ioffersomename12]

the problem here is that my friend thinks this is a immeasureable feat. when its not. its just time travel and ftl speed (I think) because its litterally the same feat as the 1987 supermans feat. and please help me about how can I convince him.

Immeasurable speed is usually something done casually. If one needs to build up heat by circling the earth; we typically use that as an argument against being Immeasurable outright. And some older era scientists speculated that traveling west faster than the earth rotates equates to traveling back in time due to the "24 timezones" shenanigans. But that was long before people fully understood the geometric scale of a space-time continuum. And plenty of authors probably ever haven't done their research, are obviously not scientists but necro topics of ancient past based on here say, or are paying tribute to older eras.
