Yeah, but you could get to California in a week with available technology. How long to get to Alpha Centauri?
It is impossible with existing or even most imagined technology...but that does not mean it is impossible.
Humans are still primitive. We have only scratched the surface of what's possible.
I have watched some videos recently in which physicists said that physics might rest on a foundation of consciousness.
I have no earthly idea what that might mean, but they said that, if true, it would upend our current understanding of physics and even reality itself.
