An instantaneous FTL drive is theoretically feasible

[qubit]

This would make the Star Trek style warp drive look like a snail by comparison. Check out the video.

I'm confident that science will one day, in the medium to far future, crack the formidable technical challenges of achieving this and achieve true space travel like we see in science fiction. That's if mankind doesn't destroy itself first, or regress due to disaster of some kind, of course.

TL;DW. Here's their website: https://asteronx.com/about.html

Not impressed. Looks like a begathon. If there is actual meat to what they're saying, I'd be interested in an academic source like NASA. I know NASA has looked into the idea (there's a thread here about it) but it's too far off to be practical at this point.

He was quoting from a source with an ISBN number in the video, which does help to provide provenance. While I couldn't be bothered to properly authenticate this just for a TPU thread, I believe that the hypothesis is real having watched the whole video and evaluated its presentation, so I can't see why it would be faked.

The whole site is dedicated to future tech that would make space travel possible in the way it is in sci-fi, so it's gonna have a sci-fi feel to it and that's ok, it doesn't discredit it. Remember, a lot of the tech we have now was once science fiction.

It's definitely not a begathon. That's really quite insulting.

It's a Patreon sponsored YouTube channel/website. Search for "Musha Jump Drive" just turns up his videos/website.

You said "this would make the Star Trek style warp drive look like a snail by comparison." What is "this?" And don't point me to Asteronx content.

Well, that's interesting, fair point. Also, your question suggests that you haven't watched the video, which explains why it's so much faster than a warp drive. It basically involves "tunneling" through the light barrier through incredible acceleration.

So, are you really not familiar with a Star Trek warp drive? What kinda nerd are you?!

Anyway, here's the real thing (still a hypothesis) if you wanna know more about it:

https://en.wikipedia.org/wiki/Alcubierre_drive

 

[FordGT90Concept]

Alcubierre drive is the first thing that came to my mind seeing the thread title. If that's what the video is about, it is nothing new. In fact, there's already a thread about it (W1zzard nails it on #4):
https://www.techpowerup.com/forums/...tar-treks-ftl-drive-may-actually-work.183964/

You'll probably recall this too which is the result of NASA engineers working with a concept artist (also Alcubierre drive):
https://www.iflscience.com/space/nasa-reveals-latest-warp-drive-ship-designs/

Alcubierre drive is completely hypothetical; however, the EmDrive has been demonstrated to work to some degree:

Ummmm.

'Tunnelling through the light barrier....'

Theoretical physics is one thing but dreaming is another. What happens to the inertia. That's a basic one. And mass? I thought going faster than light requires matter to become energy.

FTL drives, if ever possible are such a distant pseudo reality that it's hard to consider them as anything other than sci-fi

 

[SoNic67]

That pesky thing called mass. That no one can explain, but always gets in the way.

 

[R0H1T]

I thought going faster than light requires matter to become energy.

Theoretically nothing goes faster than light or can go faster than light. Special theory of relativity deals with the possibility, but there's no headway in that direction other than such hypotheses.

I doubt I will see it in my life time

tsk, you haven't actually watched the video, or understood what it's about. It's about a different, hypothetical, technology that will leave warp drive in the dust. Whether something like this can ever come to pass is another thing of course.

 

[SoNic67]

It's easy to leave "in the dust" something that doesn't exist.
I just now raced ane leaved in the dust an unicorn.

 

[bonehead123]

Say what you will, but the Q will never allow this to be built, as they are against the idea of humankind traveling outside of their own solar system, let alone to other galaxies/universes

 

[FordGT90Concept]

There you go again with the "this." So it's not an Alcubierre drive and it's not an EM drive? What is "this?"

 

[Sasqui]

I thought going faster than light requires matter to become energy.

Theoretically, mass can't go faster than light, because the mass increases to infinity as it reaches the speed of light. That is because of all the energy needed to accelerate that mass towards the speed of light, "becomes" more mass to accelerate.

 

[FCG]

Light (i.e. linearly polarized photons) remains in the same absolute location in the natural reference frame of the universe.... it is YOU that is gravitating.

While it is indeed true that matter cannot be accelerated through the "speed of light" by means of EM force, this is not true for all motive forces (for example: supernova explosion). Just because we can't use magnetic and/or dielectric fields vis a vis particle accelerator to push matter FTL doesn't mean that all FTL motion is not possible.

Matter IS energy... see E = mc^2

Matter at FTL speeds (displacements) would constitute anti-matter. Not really anti- (as this implies an additive conjugate) but rather inverse-matter as it is a multiplicative inverse.

Theoretically, mass can't go faster than light, because the mass increases to infinity as it reaches the speed of light. That is because of all the energy needed to accelerate that mass towards the speed of light, "becomes" more mass to accelerate.

This is an often misconstrued... what if the mass doesn't go to infinity as "v" approaches "c"... what if instead the force goes to zero (as "v" approaches "c")?

Traveling at FTL seems dumb compared to, for example, creating an artifical wormhole. What happens if you FTL through a star?

 

[FCG]

There is no objective basis for the existence of a wormhole nor black holes nor white holes nor any "hole" of any type.

Matter accelerated FTL would exhibit anti-gravitational motion and acts to push other matter away.
The larger concern is non-gravitating matter (i.e. EM radiation).

Same thing that happened to the Event Horizon......

[krykry]

I'm not saying it's impossible to travel at FTL speeds since we're still a primitive civilization (modern science was discovered just a few hundred years ago), but I call bullshit on the people who say they know how to do it right now.

 

[HTC]

Stupid questions:

- Don't we need to figure out how to accelerate to such speeds without killing ourselves doing it?
- And what about slowing the ship down?
- Something that has the same effect as Star Trek's "inertial dampners", no?

I mean: it's fine if we manage to find a way to accelerate / decelerate to such speeds but, and as an example, how long would it currently take for a ship with one occupant to accelerate from current "normal space speed" (25000+ KPH, right?) to ... say ... half the speed of light without killing the occupant due to too high G forces involved?
