Reminds me of the Matrix. Dilbert creator Scott Adams jokes we are in a simulation which could explain how we could be in the same place but in another moment. Love the TV show named Fringe with pocket universes which means different moments at and in the same place. In Star Trek Next Generation, some aliens went back to the 1800's to steal souls out of humans & went back to 2400 AD or so, five hundred years into the future, and these aliens lived on a planet in that future. The space astronauts went onto the planet but couldn't see the aliens because the aliens were living at a different space time velocity or speed similar to a playback video speed. You can play a video at 1x speed or maybe 0.7x speed or 3x speed. Under this theory, you would be invisible as you experience time differently like the Einstein theory of 2 babies. One baby goes the speed of light & travels a light year or something & comes back. The second twin baby stays on earth. The first baby in outer space comes back still a baby while the 2nd baby on earth is like 100 years old, or was it vice versus? Not sure. But it is interesting.
