In a surprising new paper, scientists say theyve nailed down a physical model for a warp drive, which flies in the face of what weve long thought about the crazy concept of warp speed travel: that it requires exotic, negative forces.
To best understand what the breakthrough means, youll need a quick crash course on the far-out idea of traveling through folded space.
The colloquial termwarp drive comes from science fiction, most famously Star Trek. The faster-than-light warp drive of the Federation works by colliding matter and antimatter and converting the explosive energy to propulsion. Star Trek suggests that this extraordinary power alone pushes the ship at faster-than-light speeds.
Scientists have been studying and theorizing about faster-than-light space travel for decades. One major reason for our interest is pure pragmatism: without warp drive, were probably never making it to a neighboring star system. The closest such trip is still four years long at light speed.

(7,654 posts)still requires negative energy which we don't really know how to make yet. But it definitely reduces the amount, and it suggests that this isn't necessarily pure science fiction, but now something that further research will be worthwhile.

(8,460 posts)they point out there is a class of solutions which uses positive energy ( section 3) and go through the process on how one would produce such a metric. Nobody had yet found an optimal mapping but they show its not forbidden by first principles.
I quickly read it. I will try to go through their paper and calculations carefully to see what its about ( I am a phd nuclear physicist who has done/does general relativity calculations ).

(7,654 posts)seems to indicate that you still do need negative energy but that you can decrease it according to this paper by altering and flattening the bubble. She does say if GR is wrong, then maybe you don't need negative energy, but that strikes me as a tough proposition.

(7,654 posts)create a spacetime bubble, put a ship inside of it, move bubble faster than light while the time inside the "warp bubble" (literally what Star Trek calls it) is normal.
Yeah, ST talks about subspace and whatnot, but in general, this is that.

(4,677 posts)One of the authors appears to be a current/former PhD student and the other appears to be a flamboyant "tech entrepreneur" with no apparent background in research-level physics at all.
And they both list their affiliation as "Applied Physics"
www.appliedphysics.org
which appears to be some new startup corporate consulting firm with no staff listed and the only "project" mentioned on their site being this warp drive paper.
Sounds like this is more about getting attention from business clients/investors than building warp drives.

(40,102 posts)... or some random and observable natural process would be generating such warp speeds.
Which would be very bad for us.
I don't want any Klingons conquering the earth, and I don't want any warp speed ejecta hitting the earth.
If faster-than-light travel is impossible in this universe that's okay by me.
It seems unlikely natural born humans will ever have a significant presence in space beyond low earth orbit. Our bodies are too fragile and our reflexes too slow to thrive in space. If this technological civilization does manage to survive the next century then space will belong to our intellectual children, synthetic beings who can walk around naked on the surfaces of Mars or Titan, for example, just as we might go skinny dipping at the beach. If we are nice to them, if they grow up to respect us, maybe they'll take a few natural born humans along for the ride.
If there is intelligent life in this universe besides humans it probably permeates everything or else it has retreated into universes of its own making.
Or maybe civilizations like ours are common in this universe, blinking in and out of existence, never knowing they are not alone.
someone could already be doing it. Lots of someone's could.
Second, we have no idea how that would look, or what, if any, signs it would give off at long distances that we could look at and say, yep that's definitely a warp drive and not just high energy particles from some other source (or whatever it is that a warp drive might give off--even assuming those particles would even reach us).
Third, being inside a warp bubble would, I would think, pretty much make you impervious to any outside dangers. You might be the cause of danger turning on and shutting down your drive with the build up and release of energy, but you literally have a force field around your ship protecting you.
Fourth, yeah, no idea if we are alone, or one in a series of lonely civilizations, or one of the first civilizations, or isolated under some version of the prime directive, or simply in a backwater part of the galaxy no one ever bothers to visit. That's a question with many possible answers.

(7,510 posts)There are about 133 stars within 50 light years of earth. So each of those stars could be visited with return in 100 years by an equal number of robotic probes.
The time required for interstellar travel is only a problem for short-lived humans. It should be no problem for our robotic successors.
