Faster than Light travel? NASA's Advanced Propulsion Lead, Dr. Harold White

[2MuchMark]

Fucking, fucking amazing



Warp Drive / Faster than light travel close to being a reality. Ignore the crappy sound quality at the beginning (until 1:45 or so). If you're a science nerd like me grab a coffee, set this to full screen, and watch the hour-long presentation. The Future is now. Drool, drool drool.

[Mr. Garibaldi]

[freecartoonporn]

i am gonna watch it.,
thanks for this.
and no, i am not trolling, if this the future then sure i would love to see it, i hate long flights

[EddyTheDog]

I watched 15 mins - I think I will need a few more coffees before I watch the rest - Way too early for this sort of thing...

If it's what I think it is, it's where they warp space from in front of the craft and the rear, essentially bending space time and shrinking the distances in front of you.

Cool thanks for posting this.

[ilnjscb]

right now is would take the energy of the mass of Jupiter to power it - but some guy will figure that out assuming you stop killing all smart people

I know what you mean... Kinda slow and boring but the concepts are amazing and seem legit. Especially considering the fact that he ran actual experiments and succeeded... just.. wow

Thats right, but don't forget the original concept required alot more energy... and if you watch the video, he was able to prove the theory correct with a tabletop experiment, and much less energy... Faster than light travel, without acceleration, and without time dilation effects. This is amazing mind-bending stuff!

I'll give you that - if he is proven correct it is the most important mechanical invention ever. The wheel, the plane, the combustion motor, the plow harness, refining, the battery .. nothing compared to this.

Disclaimer: I did not listened the whole hour, just looked here and there, and I am hobby about this, not recognised by science bodies.

But for sure, the guy did not invented the concept, there's 1990's experiments, and older theories, see Alcubierre. So that empty space itself (quantum vacuum, spacetime metric) might be used to provide energy=thrust for space vehicles by certain matter/vacuum interactions.
Wikipedia: In quantum theory the vacuum is the seat of energetic particle and field fluctuations, and in general relativity the vacuum is the seat of a spacetime structure (metric) that encodes the distribution of matter and energy.

Also, the Alcubierre shape he uses it seems outdated:



See here:

http://arxiv.org/pdf/1208.3706v1.pdf
http://www.hindawi.com/journals/isrn...s/2013/482734/
"we have analyzed the Alcubierre warp drive mechanism within the framework of Conformal Gravity. We have seen that a particular choice of the shaping function (Hartle shaping function, instead of the original Alcubierre one) can overcome the main limitation of the weak energy condition."

A better shape it may be Hartle function instead (for what anyone knows):



Just, the Hartle shape it looks less cute (or making sense) for sci-fi movie visuals, and this may be why the NASA guy kept the Alcubierre one.

To see how old is the stuff the guy in the video talks about, using google you find that in 1988 nobelist T.D. Lee in his textbook "Particle Physics and Introduction to Field Theory" stated: “The experimental method to alter the properties of the vacuum may be called vacuum engineering…. ".

Let me talk of the time issue: to do this vacuum engineering, even if you really can make it happen (and stable space and gravity inside the bubble, so no one is smashed by acceleration or so), you have most probably to alter time, more in detail have time clock different in the bubble than outside. Create a time-slowed (or time-turbo) condition inside the bubble where spaceship to be for a "while" within such a temporally-modified field. So when returned to the normal space, spaceship astronauts will experience "missing time", much like Planet of the Apes (1960's movie) or most likely vice-versa: time outside was slowed down to blocked, so the spaceship move faster-than-light... for 10 minutes in outside-world time, but inside the ship that was 10 or 100 years time! So you transferred super-luminal warp speed (10 minutes instead of 100 years), but the side effect of the trick it is: you're receiving the elder children of austronauts, even if after just 10 minutes of our time. This may be still good to transfer robots or minerals, but not so much the lifeforms - either planet of the apes effect, or the inverse effect - a warp sailor would never find own wife and friends after the warp, as either him or the people outside died of natural elderness.

Other issues it comes to my mind: if you travel so fast in direction of a light source (like stars) you're getting those photons concentrated to a point it is a laser burning the spaceship. Shoud the bubble have an antimatter shield, whatever. This is much like sailing against the wind at super speed, but with light particles instead of the wind (and there may be same effect of Mach 1 for sound waves in jets http://en.wikipedia.org/wiki/Mach_number , but when you go faster than light, the light concentrates when you're same fast as light, and burns all).

[bean-aid]

Why don't they model the typical spacecraft discs like in sci fi movies? Since the vaccuum is created by a spinning disc... makes the flying saucer concept more plausible.

[Dirty F]

I will explain it all to you fools tomorrow, when i'm sober.

[Mutt]

So if this one day is feasible does that mean humans could time travel into the future and view their descendants? And time travel into the past? Or it just means we could travel to distant planets faster than the speed of light?

So the people in this warp drive craft would get to their destination in perhaps hours/days but here on earth all the people they knew would have been dead for hundreds/thousands of years.

[12clicks]

Huge difference between theory and application.
Lets worry about replacing fossil fuels in a 1:1 ratio or we really won't need to worry about this theory.

[DVTimes]

[Mutt]

I'd prefer they work on human immortality myself. None of us will be around when these incredible things take place.

[Socks]

if you're travelling really fast in space, aren't you going to hit a lot of rocks and space debris?

and.. mass x velocity.... kaboom

No, that's not it. This is basically faster than light travel, but without the time effects that Einstein talked about.

Normally travelling near the speed of light slows time down for the traveller, but by compression space instead, time inside the space ship remains unaffected. So say, 2 weeks of travel time for the space ship would equal 2 weeks of time on earth too. No time travel, no paradoxes, no traveller aging slower than his earth-bound brother, etc.

[adultmobile]

Someone will bump this thread after 100 or 200 years and tell the results.

[adultmobile]

BTW, even if could do one, it would be unstable:

http://arxiv.org/pdf/1111.4356v2.pdf

"superluminal warp drives are quantum mechanically unstable because they produce a Hawking-like radiation which is blue shifted at their front wall without any bound. When the dispersion relation is subluminal, the horizons act as a resonant cavity producing a dynamical black-hole laser instability. When it is superluminal, instead, the emitted flux grows linearly in time due to infrared effects."

Had not listened that, now I have. The question is made about radiation, so particles, i.e. photons which move at speed of light and nearly no mass - like in thing I quoted. But, the NASA guy mostly answers about "stellar dust", which is matter like debris in gravity movie, that got mass and move slow. I don't think the NASA guy answered properly.

[bean-aid]

I have no idea really as it is just theories. I thought he said the matter would not build up, in front, because the matter would pass through the warp at same speed ship was going prior to warp because inside the warp is no acceleration. Shrinking space in front and stretching behind, which makes distance in warp seem much shorter.

Still, wouldnt hitting a rock at 10000 miles/hour do some serious damage... lol

Everyone here knows Miguel Alcubierre, Director of the Nuclear Sciences Institute at the National Autonomous University of Mexico, first proposed this method of propulsion. I have said in another thread he deserves the Nobel.

It does not take away from a theoretical nuclear physicist to have someone validate their experiments; indeed, I believe it is encouraged

Even light has a place in time and space, and is somewhat defined by them. Your statement above, and I mean no disrespect, reminds me of the reports of people who claimed that traveling at train speeds would be detrimental to the health of the travelers. Rest assured, unless they keep killing off smart people in the interest or retaining power, someone will invent a way to get around the problem.

[NETbilling]

People is smart and they can't find a crashed jetliner in the ocean....

[Mutt]

I wonder if Stephen Hawking would trade brains with somebody like DVTimes if he had the opportunity, meaning he'd be disease free, body would function normally but would live out his life as a simpleton.

Adultmobile disagrees, he says either the space travelers inside the bubble age say 100 years in 10 minutes of warp speed travel time OR it's the people down on earth who would age 100 years while the space travelers only 10 minutes.
