4/2/2023 0 Comments Anything faster than lightDo we allow an existing “space tunnel” (like the wormholes of general relativity)? Perhaps a space tunnel that has been there since the beginning of the universe. It’s a little tricky even to define what it means to “go faster than light”. And that in fact there is a way to “move through space” faster than light. But it’s also conceivable that there may be some clever “engineering solution”, as there have been to so many seemingly insuperable engineering problems in the past. And one that can’t be solved with the computational resources available to us in our universe. But it may well be an irreducibly hard engineering problem. And I’ll say at the outset that it’s a subtle and complicated question, and I don’t know the full answer yet.īut I increasingly suspect that going faster than light is not a physical impossibility instead, in a sense, doing it is “just” an engineering problem. But is this actually true? We’re now in a position to analyze this in the context of our model for fundamental physics. Well, then tell us if warp drive is possible!” Despite the hopes and assumptions of science fiction, real physics has for at least a century almost universally assumed that no genuine effect can ever propagate through physical space any faster than light. “So you think you have a fundamental theory of physics. When the NASA Innovative Advanced Concepts Program asked me to keynote their annual conference I thought it would be a good excuse to spend some time on a question I’ve always wanted to explore…
