"invisibility" devices already exist. The work by bending light from behind an object to the front of the object.
Oh yeah I saw this documentary of a guy who was wearing 2 screens, one in front and one behind, and you could literally see through him (through the 2 screens).
Now we just have to make the screens invisible...

I'd like to take a brief moment of unshifted temporality to point out that nobody has ever seen the invisible, either. If anyone had, then the invisible would, ergo, be the visible.

so can i have my time machine now?(what the deuce was the logic behind that proposition anyway???)
This one's my fault, I didn't clarify.
Nobody has ever seen a time-traveler before, so among the possibilities:
- Time travel will never be invented
- Time travelers are wearing an invisibility suit for some reason, e.g. legal mandate, personal preference to not risk dating your mom or something like that.
Expanding from the 2nd possibility: ergo, invisibility must have been invented before time travel.
You know how sometimes dogs start barking at empty space for no apparent reason? Maybe they're barking at invisible time travelers.
