Comment on Implications

Or it could be like a time portal so once you build one you an travel back to any point it existed in but one to a point where it doesn’t exist since you need time travel infrastructure

Or the technology for invisibility arrives before time travel so they were there, just undetected. Absence of evidence is not evidence of absence.

I mean, that for the most part makes sense. Although in that case, wouldn’t it have been reported that “no one attended the party but the food and the snacks were somehow missing”?
That said. Unsure how exactly it went but I read somewhere that if you had the power of True Invisibility, that is being undetectable at any wavelength of light, then you’d basically be able to simulate negative mass, and from there to “time travel” it’s kind of a straight line.
