@barrygoldman1 @oelma__ I cannot say what purpose the person who posted this actually had in mind. I assume it merely a mental exercise in observational acuity. A famous astronomer once said "purpose is only a dream in our minds, and is not visible in the universe."

@AstroBioProf @oelma__ ummm mr Geller... what sort of accounts are these and what is the result of reposting them?

Wait a second 🤔I Still Can't Find The Difference.
