Well Helios, if we did suddenly pop out of extience, we would all do it at the same time - or else people would just see people randomly diapearing and reapearing on the street
Also, things like the sun and the earth wouldnt dispear, or we would have known, we can notice a split second of darkness, feel a split second of falling etc, and i have never experienced this.
It is possible, but highly unlikely, that could cause alot of problems, like if someone dispeared the second someone punched them in the head, when tehy reapear they will be in the same space as the fist and somethign werid would happen.
The Memory is a weird thing, a goldfish has a 5 second meory span right? So do they disapear out of existance every 5 seconds? that would create a disurbance in the water and we would see it - right?
Anyways, i know absolutely nothing about physics and

so i pulled all this outa my ass, but ti makes sence to me
