Nasa scientist has created a warp drive in his garage and demonstrated it

a reply to: stormbringer1701

The fractal array design of the motor reminds me of fractal antennas - self similarity amplification.

The guy is certainly committed. Regardless how it turns out, it's important to know what doesn't work as well as what does - I hope he publishes at some point.

So I havent seen this posted, but I did find it on reddit.

You saw this on reddit, please post the reddit link. Cutting out that community from this thread loses a lot of research that is likely already complete.

Are you guys kidding me? Is /r/technology really this gullible? This is complete bull#. From his failed indiegogo:

David Pares has a MS and a BGS in Geography and an AS in Engineering Science.

He doesn't have any formal training in physics. This is a clear case of too good to be true.

He believes warp bubbles already occur. For decades he has been drawn to case studies of pilots apparently thrown off course and, in some reports, projected hundreds of miles ahead while trying to navigate through storms. He is especially enamored with the story of Bruce Gernon, an experienced pilot who in 1970 flew into what is commonly called the Bermuda Triangle. Facing a fierce thunderstorm, Gernon steered toward what appeared to be a small break in the clouds, only to emerge 100 miles ahead of where he should have been.

Holy #. This is what his theory is based on? BS Bermuda triangle stories? It's called a tailwind. www.csicop.org...

Shame on you /r/technology.

Here is the 'inspiration' for this gentleman's work.



This is a short video about a pilot that flew into a storm that apparently warped space.

It does not seem that there was any space warping. It was the magnetic storm creating a an aerodynamic frictioness tunnel.

If it as actual warping, he should have come out the tunnel as soon as he entered it.

that would be true of a stargate type wormhole but not necessarily all forms of warp. also wormholes have an arbitrary tunnel depth except the stargate type.

Oops, looks like the pilot encountered a pocket of time anomaly. Lucky he came out unlike mh370 and other disappearances in the triangle.

sciences best guess about what a worm critter would actually look like based on ray tracing photon models (models that simulate what happens to photons going through a wormhole and what that would do to images from the near mouth and far mouth.

so anyway according to the best scientific wild *ssed guess available: a wormhole does not appear to be a funnel. Instead it appears as a sphere with distorted edges and when you look through it to the far end the image is inverted left to right.

like this: physicsbuzz.physicscentral.com...

EDIT: So if these airplanes are going through some type of warp phenomenon it is not a wormhole but one of the other species of spatial or temporal distortion.

EDIT 2: By the way this modelling of what a wormhole would look like was originally commissioned by the maker's of Carl Sagan's movie. when the physicist's presented their findings; the movie people said something along the lines of "that's nice but what we wanted was the funnel sort of thing" and the scientific version wasn't used.

Yes. That's because the motor *is* a fractal antenna

There is a huge class of EM type drives that all theoretically operate along the same general scheme. there are other families of course such as the rotating conductor or super conductor family including Tajmar and Podkletnov among others.

No, wormholes cannot have arbitrary length tunnels. There is no spacetime inside a wormhole tunnel.

nope you are wrong. time does exist inside a wormhole except stargate type ones.

otherwise there would be no need to wait any interval for a wormhole to become functional. in Dr Cramer's example it takes 59 weeks for the wormhole to become functional because that is the time dilation squeezed amount of time the distal end experiences before arriving at it's target. Additionally; not all wormholes are user friendly. if the space curvature at the throat is too abrupt tidal forces will turn you into spaghetti much like a black hole will. so traversible wormholes have to have a certain geometry in addition to the cosmically imposed limits on them.

generally there is some travel time involved in traversing a wormhole. that time or length if you prefer is not commensurate with the global distance between the ends though. not sure exactly what determines that length. but there usually is a length. the exception again is a stargate type wormhole but i have no idea what the rationale is for the difference is unless it is just a name fora really short interior wormhole. like a ruby is a corundum just like sapphires but only a red corundum is called a ruby.

that video i linked to earlier is very informative on wormholes and how they may potentially be grabbed, enlarged, maintained and steered as well as limit on wormholes due to causality protection principles and mechanisms such as cosmic back reaction.

Oh. I see what you are saying. Once established there is zero time inside the tunnel. Yes. You are right. Once the wormhole link is established it requires almost no time from entry to exit. Yeah i think that is true.

So at what location is the exit, co-ordinates?

that depends on where you put it. cosmic back pressure is a theory originally developed to enforce causality protection conjectures and to destroy traversible wormholes before they can be used. but it turned out that it also provides ways of maintaining and even steering a wormhole if you are careful about it. this is because whatever you do to one end or what ever you put through one end through the conservation principle effects the other end. you can charge one end and the opposite charge appears at the other end. you can chuck stuff through and the velocity acceleration effects the other end. you can thus use the back reaction to move the distal end in any direction you want. if you send a relativistic collider beam through the wormhole the other end gets imparted relativistic acceleration. if you pass a flux line through you can create unitary charges of stuff that normally does not have unitary charges like magnetic energy. you can even change the sign of the values of matter and energy.

long story short: in principle you can aim and steer and move the other end in whatever way you want provided you do not create a forbidden closed time like loop.

delete. Double post. thanks in advance.

it let me read it for free...people still fall for pop-ups these days??

so is this bullsh.. or?

no one can tell for sure with out a heck of a lot more information.

over at NASA Space Flight Advanced concepts forum White's Cannae/Shawyer EM drive test has been debated for about 1200 total pages between two threads with genuine scientists and engineers debating it and analyzing everything in excruciating mathematical detail. they still won't rule out experimental error. and that is with full disclosure of all the technical details and protocols and one of White's test team engineers providing additional details.

there is no way in heck we can tell for sure about this topic without at least the amount of information available for the eagleworks test being available for this. so it's down to opinion. and opinion is not science.

Seeing as scientists predict a warp bubble could accidently destroy entire solar systems if you come out of one wrong I think the defence implications would garentee this aint going public if true.

That's false though. That assumes a bow-shock of FTL matter that doesn't decellerate like the ship would. That would be as much a violation of physics as saying the ship is really FTL. In a warp drive space warps (FTL or otherwise) but the matter in between doesn't move at all or above the speed of light. That is in the warp-stream plane example the whole thing was based on - the air wasn't moving any faster than the wind was, the plane wasn't moving any faster than it was before it entered the warp bubble - but the plane entered a space where space itself wasn't as dense meaning the same thrust took it further hence it moved hundreds of miles relative to elsewhere but relative to it it never moved faster than it was already going. If a warp drive would destroy the solar system then apparently the solar system would have been destroyed a long time ago during the first thunderstorm.

What Dr White says about this that the only speed boost that anything from space dust to photons will get is when it passes through the interface between the bubble and normal space. inside the bubble nothing is moving except at the speed it had prior to entering warp. the ship is practically at rest (Actually it is moving at the speed it had when the bubble was erected.) there is no abnormal acceleration in the interior region and since stuff passes through the "skin" of the warp bubble there is no accumulation of matter or photons at the boundaries of the warp field either.

there is a collision hazard but it is no greater than that of the combined normal space velocities of the objects in collision. That's still quite dangerous. dust is like a high powered rifle bullet, grains are like an armor piercing round gravel is like artillery shells or missiles, bowling balls are like atomic bombs.

Though formidible; we do have technology that could protect against such impacts. fortunately the ones greater than dust are very very rare even given the volume of space that can be gone through at those speeds. For example; at high relativistic speed you can expect one dust bunny impact per square meter of frontal cross section per day. grain sized is rare and the larger ones are successively more rare still. dust and sand grain sized impactors can be swept aside by electrical or magnetic fields. gravel sized ones can be handled by automatic radar/laser combinations.

bigger ones are so rare you might not hit one at all in an entire interstellar voyage. but presumably you can dodge big ones because you should have time between seeing them and impact to do something.

Also there is one effect that is true because of the interface between the two spaces: optical rules apply. something entering a region of different density to the one it is traveling through will have it's path bent defracted or refracted. with a little luck or planning this means stuff aiming dead center of your line of travel will deflect away from it on it's own.
