So how does that beacon (if physical) get placed in that time and space for them to do the computations from its feed back? Did he explain that? Or is it some parallel super-physics that can traverse through time and space and they get fed back faster than the speed of light? It's all gobbly-gook.
While I love science and these brilliant people, they come up with their theories to expand on other theories and then try to prove it through math. They'll never know. Like I said, what happened to "string theory"?
String theory is in trouble given the current state of dark matter and gravity as an emergent force.!? I think he said a tacion pulse like Star Trek actually. Also he only said it “may be” possible. And it may. Worm holes may be possible. Converting matter to energy and back again may be possible too. Who knows what the future holds.
Oh yeah. It’s too late for me to find it for you but I recall a laser fired through some gas in some state either traveled time or faster than light and the flipping of the switch.
