It's racist to call advanced things 'white', even if it's the name of the guy.

If we all nit picked like you we'd never get off this planet. If you create something worth naming feel free to name it after yourself no matter what your name happens to be.

To swift, I don't know what your background is, nor do I know the background of the people you were having this hypothetical discussion with. I didn't understand a good deal of it but it was great to watch. Thanks for the enlightenment. I am so tired of meaningless kardashian exploits you have no idea

Hmmm... maybe a warp isn't necessary, perhaps bend or a nudge.

A nudge drive, or a bend drive will probably come first.-)

"Already some studies have claimed to find possible signatures of moving space-time. For example, scientists rotated super-cold rings in a lab. They found that still gyroscopes placed above the rings seem to think they themselves are rotating simply because of the presence of the spinning rings beneath. The researchers postulated that the ultra-cold rings were somehow dragging space-time, and the gyroscope was detecting the effect."

I love "between the lines" bits of reality such as the above.

The "studies" referenced above are from some pretty questionable sources. But then... naive people will believe pretty much everything with the words "superconductor", "rotating" and "scientist". In the past they promised to make gold and rain, today they are promising to make free energy and to make space-time move. No difference in the human psyche, though.

More questionable than you? I doubt it. Your rationality is starting to come across as somewhat forced.

I've known individuals, who could read a book. Finish school and still be tragically devoid of creativity, the capacity for synthesis the cognitive wherewithal needed for true discovery.

Or the courage.

Bwaahahahaaaahaaha... lot's of believers here... not a lot of people with common sense... and nobody who actually understands the physics slight of hand that's happening here.

OK... I give it to you, it's not completely trivial. Here is how they cheat around the laws of nature:

1) They use ordinary general relativity, which does not allow for a local speed of light that is faster than c.
2) Then they assume that they have copious amounts of a new form of matter which has negative energy density, i.e. it acts like there is no space there.
3) Then they churn the machinery and... out pops a mechanism that accelerates things to faster than light.

The problem is in step 2). There is no such matter in this universe. That happens to be synonymous with the requirement of the theory that one can not exceed the speed of light in vacuum.

There is a much more simple example of this in thermodynamics. If you let go of the third law of thermodynamics, which requires that the lowest possible temperature on the absolute scale is 0K, then one can introduce temperature baths with negative temperature. Used in a machine based on an ideal thermodynamic cycle, like the Carnot cycle, the machine will be able to have an efficiency >1, i.e. it will generate more power than it consumes. And... there it is... perpetual motion.

Good post. Nice explanation. It's an interesting idea to contemplate, though. To me, stretched space aft of ship seems akin to riding crest of an event horizon. Likewise, compressed space is akin to ship bow moving toward singularity. That said, I don't know how visionaries intend to safely recreate effects of a bow side linear accelerating singularity to warp space in like manner.

If someone figures it out, you know, it's likely going to be some young upstart who ignores general physics consensus, visualizes solution to the problem with a new paradigm, then works backward to legitimize.

It's a daunting problem. I've got no idea how you could generate, concentrate, and control so much power at one focal point.
04:13 AM on 09/19/2012
Well, you can argue that it's a solution to the equations... but equations always have unphysical solutions, that's nothing new. There is a whole line of theorists who are enjoying working out the math of those. And that's OK... but what is not OK is to pretend that these solutions have any applications. I think there is a bit too much hype about this stuff, and that's not good for physics. Eventually people can figure out that it's just a hypothetical and not reality and then they get the wrong ideas about science in general.

" I've got no idea how you could generate, concentrate, and control so much power at one focal point. "

The same way you stop your perpetual motion machine from running ever faster and faster and faster until it blows the world apart?

I don't think anyone in the article was suggesting that this drive would allow one to exceed the speed of light. Indeed, they say the opposite. By warping space, the theory is that one can travel distances in such a way as to have an effective superluminal speed without actually breaking that limit.
06:19 PM on 09/19/2012
No, actually, the idea does claim to exceed the speed of light. And it does claim to do so locally.

"By warping space,"

The drive does not warp space globally, so the observation that general relativity does allow for objects to move away from each other at more than the effective speed of light, does not apply. And even that is accomplished by nature by actually creating more space between the two objects, which the drive does not claim to do. Once you "shut it down", the local distortion disappears, we are back in flat space-time, but the machine is supposed to have traveled faster than c in a flat metric.

I volunteer! If the technology singularity doesn't come, I'm going to cryo-store freeze myself until we have warp drive!

You are right about Star Trek becoming a reality. But, it is not "awesome" in the sense you MAY intend, but "scary". Do you REALLY know what kind of "people" made shows of that nature?

I always believed that there is no speed limit, speed of light or otherwise. So long as you can measure the speed of something it's not the fastest thing. It just becomes the fastest thing you can measure.
12:35 PM on 09/19/2012
I understand what you mean, but its a little more complicated then that when it comes to the speed of light.

The speed of light being the cosmic speed limit does not hinge on your belief. You ever use a GPS? They ONLY work because the speed of light is the cosmic speed limit.

If a vehicle were designed that could travel at 10 times the speed of light, wouldn't a trip to the nearest star still require about half a year of sustained flight? Still unbelievably impressive compared with our present capabilities, but traveling for about five or six months and not being able to communicate with earth once there??? An advanced communication system needs to be devised first, high speed flight second.

"Now physicists say that adjustments can be made to the proposed warp drive that would enable it to run on significantly less energy, potentially bringing the idea back from the realm of science fiction into science."

...Translation : Tweaking the laws of physics to establish foundation. Still sounds like Star Trek to me. I guess the word "potentially" lets them off the hook...

Quote :

" "The additional energy reduction realized by oscillating the bubble intensity is an interesting conjecture that we will enjoy looking at in the lab."

...Translation : We'll have fun trying.

A little bit ? He said it twice. Means he wasn't joking...

I defer to Shakespeare :

As dreams are made on; and our little life
Is rounded with a sleep."
