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.
