"I wouldn’t expect a warp drive breakthrough any time soon, but laying a theoretical basis for a technology has to be step one."

Not too early to start buying tickets

What a fascinating idea! I never thought of it that way! Thank you for passing clipping this

Urgh, I meant thank you for clipping this (passing this on)

And that’s the key — the speed of light stricture does not apply to spacetime itself. Can we learn how to generate a region of expanding spacetime and one of contracting spacetime?

Actually that's the easy part. The hard part will be long range scanners, navigation and not blowing up the universe while we are in a hurry to get somewhere. There was even an episode of Star Trek (the showcase of the fabled warp drive technology) that dwelled on the fact the the Starships were creating voids in space from the effects of warp drive use.
