NASA: Working on Proof Of Concept for Faster Than light Travel.

Moving near or faster than the speed of light is either impossible or impracticable under our current laws of physics (which will almost definitely change or slightly alter in some way). This kind of concept is much more plausible to me and I think something like this will eventually lead to human interstellar travel. That is unless we find a wormhole first (if such things exist).

One of the main problems with any near-instantaneous speed is the g-force on crew. That much acceleration in so short of a time would create horrendous g's - I have no idea what levels but that would have to be seriously looked at.

I don't see this as a problem. I see it in Sci-fi all the time. However in this scenario If the perception is speed as a result of expanding and shrinking of space time as a propulsion source then a continuous moment should be inexplicably smooth. You have to remember that space time is what is moving not the space craft.

How far apart should the magnets be? I think the distance between each magnet should become greater as acceleration increases.

Did he steal this from futurama? In it the ship uses the universe to propel it, not the ship propelled through the universe.

I wasn't referring to the space bubble method proposed in the video/articles of the op. I was referring to other methods that would 'shoot' the ships into space such as the rail gun idea. That instantaneous speed would be too much, i believe. Who know we can probably work something out.

Not exactly, more like mixing the futurama method with the ship moving forward. The ship still has its own relative speed, plus the expansion/shrinkage of space. As he states in the video there has to be some initial movement/velocity by the space ship for the system to work or the bubble leaves the space ship behind. Basically the ship has to move to maintain its position within the constantly moving bubble.

That would definitely help, the longer the 'barrel' the faster a speed that could be attained. Basically the increased distance would give the ship more time to gain momentum as the magnetic pull has a longer time to speed it up. But the best situation is to have the magnets consistent distances apart and a lot of them instead of a series of 5 or 6 spaced increasingly far apart. That way it would be easier to build the speed consistently over that distance. Another thing that could help that I don't know if they are working on is reversing the poles of magnet once the ship has passed. So that they could pull from the front and push from behind. That, i think, would build speed faster.

However i would think any of these rail gun situations would require the use of a 'rail(s)' to keep the ship on track down the center of the barrel if you will. Otherwise hitting the next magnetic field could push the ship off course. Because they are rings 'projecting' from the source the ship would be inclined to push around whatever rings it hit, the guides would keep it on track. Even in the cases of only (+) and (off) there would/could still be residues to push off course. The way I have had it described to me is even with electro-magnets (which these would have to be obviously) they create 'a disturbance in the force' where when the magnets are first turned on or off the magnetic rings aren't pure and can cause havoc pushing the vessel off course. This is what the guides would protect against. If you had increasing distances between the magnets that would increase the danger of getting pushed off track as the next magnetic field would have to be that much larger to pick it up and when the ring gets bigger the ship is hitting the rings at a worse angle tangentically making easier to slip off course(word/spelling). You want the ship hitting each ring at the same relative angle as the one before. (i think)

But i could see the whole 'gun' easily being a kilometer to a mile. if nothing else to ensure it is going in the right direction when launched. (absolutely critical- predictive shooting to the max) The great thing about how many magnets they would need is proportional to how much power they feed into each magnet, basically how strong is each magnet vs the overall acceleration needed. Again I think more at a lesser power would give a smoother 'shot' than fewer with more power. As to the spacing between magnets I couldn't begin to guess, 50' - 100' maybe???? There is a lot of math/theory in there that I certainly don't know. And these magnets would be huge too, a ring a maybe 200' in diameter, 10' deep. Again this is all speculation to numbers because it varies on the speed they wish to attain for the ship, and how many magnets they want to use.

It's been awhile, but I don't think it was aliens in that movie. I think they went through a wormhole and when they came out on the other side they were in hell.

ah ok, never saw the movie. I think the sci-fi theory excites me more than the lore (movies/books etc etc)

I am fascinated by the concepts you're talking about but when combined with your avatar I can't help but laugh a little. :p

get your mind out of the gutter squirrel. :)

I actually blame my parents for my fascination with sci-fi and fantasy stuff. They had me play too many sports and out doorsy stuff, and always treated sci-fi and fantasy as the 'no don't do that" So I rebelled against my parents wishes to become a nerd. Cool story bro, I know. :pepper:

How many G's can the bean bag attain when hurled at the hole in the board? :lol:

People said man could never fly, then they said man will never reach the moon!

We went from first flight (Wright brothers) to landing on the moon in just 66 years.

You don't think its possible with what technology might come along in the next 50-100 years?

While I see where you're going let's face it...this isn't the same thing. Humans had witnessed flight all around them forever.

Realistic travel at FTL speeds is a pretty big deal.

Thats the point of this whole space bubble theory. You get the bubble moving at almost the speed of light and the ship inside the bubble moving as well the apparent speed of the ship going could be faster than the speed of light. That is what my mind thinks anyway. I always compare this bubble to walking from one end of a plane going just under the speed of sound to the other. As far as the world is concerned you are walking faster than the speed of sound, but according to the plane you are only walking. So in this case the space ship is 'walking' inside the bubble which is also moving, increasing the space ship's apparent speed while not breaking any rules. And even if we only got to 99.999999% of the speed of light that is still amazingly fast and could make settling planets in other solar systems a possibility.

With science pushing back the boundaries of pretty much everything we know almost daily, I have a hard time thinking there's anything absolute in the world or specifically being able to say "that can't be done."

I mean, the laws of physics are one thing, but laws are meant to be broken.

We'd still have to get suspended animation or some form or cryostasis perfected before that could happen. Unless you are talking a generational type star ship, which would end up being pretty large.

In the 1920's and 30's even 40's and 50's people felt the same way about the sound barrier. Pretty interesting thoughts people had about what would happen, take a moment and google it.
