What does /sci/ think about the Alcubierre model, within our lifetime?

[Anonymous No.5549659]

not before immortality

[Anonymous No.5549663]

>>5549659
Both would be nice.

[Anonymous No.5549669]

>>5549659
Haha, witty!

[Anonymous No.5549721]

No chance at all. And probably not ever.

[transfer student F No.5549738]

i'm working on it, but also like immortality i don't plan on making it available

[Anonymous No.5549757]

The real question is do we really need faster than light travel if when you approach light speed time slows down?

Anyway relativity is wrong, so none of this makes sense

[Anonymous No.5549780]

please help correct my understanding of this. the Alcubierre drive is powered by exotic particles which currently don't exist in our universe. Ignoring how we get them, when we do have them how do you control them? It would appear to me that once you have an Alcubierre drive that's turned on, there's no real way to turn it off.

[Anonymous No.5549794]

>>5549780
I too have a very limited understanding of the drive, but the whole hype about a new 'theoretically possible' design has peaked my interest.

>exotic matter

[Anonymous No.5549802]

>>5549780
Isn't it antimatter?
We can generate antimatter.

Barely. At a huge cost.

It's something.

[Anonymous No.5549805]

>>5549802
I think you're reffering to matter with negative mass, but the new design refutes the need for negative mass. There are still other big problems though

[Anonymous No.5549815]

>>5549802
No it's not anti-matter. It's referring to some other form of exotic matter with certain properties that we have never observed to exist.

The type of matter required is ill defined.

[Anonymous No.5549832]

>>5549805
>>5549815
Ah. My mistake.

[Anonymous No.5549864]

>>5549650
Eh... I believe it could work as something like Stargates, Starbubble would be a more appropriate name/state though.

Otherwise it's simply outclassed by other functions

[Anonymous No.5550007]

something called negative energy density is required. A good analogy is that it creates a high pressure behind the ship with a lower pressure in front, so therefore pushes it forward. However in this case it's a warping in space-time which thus causes the space-time around the ship to move at theoretically greater than the speed of light

[Anonymous No.5550251]

>>5550007
high gravitational distortion in front, negative gravitational distortion in back. Wouldn't the ship move forward crashing into the high gravitational distortion and then stop moving once it's collided/merged with the high grav distortion?

Only way to make this work is if you made both gravitational distortions move along with the ship. But if they're both moving with the ship then wouldn't all the forces cancel out? Seems a little bit too much like troll science to me.

[Anonymous No.5550268]

By the way, why doesn't anti-matter have negative mass? I mean everything else seems to be reversed, charge, spin, etc.

[Anonymous No.5550271]

>>5549650
probably soon after singularity. so probably yes.

[Anonymous No.5550274]

>>5550251
The ship isn't moving.

[Anonymous No.5550276]

>>5549650

Maybe after I get my Marilyn Monrobot.

[Anonymous No.5550283]

>>5550268
Anti-matter is still matter. It's just been turned inside out. It has all the same particles and sub-atomic particles, more or less, of normal matter there for it has mass.

What the Alcubierre model requires is not anti-matter but an anti-particle....if that's even the right word.

[Anonymous No.5550285]

>>5550268
It might, we don't know for sure yet.

[Anonymous No.5550319]

For this to work, we'd have to get exotic matter or generate enough energy that would propel matter passed the speed of light, anyway.

[Anonymous No.5550523]

The only hope for generating a negative energy density (for the moment) is through manipulating the vacuum expectation value. For example, see the Casimir effect. The problem is that negative vacuum expectation energy has incredibly low density and warp drive metrics require enormous densities. Also, we aren't show that negative vacuum energy actually couples repulsively to gravitation.

The most troubling problem of warp drive was pointed out by Krasnikov. Suppose you could generate the warp field. How do you move the matter that generates the warp field?

There are some very serious fundamental issues that have to figured out before we can even guess how feasible they are.

>At its peak, Starlab employed over 130 scientists from thirty-six nationalities. Starlab projects included intelligent clothing, stem cell research, emotics, transarchitecture, robotics, theoretical physics, e.g., the possibility of time travel, consciousness, quantum computation, quantum information, art, artificial intelligence, neuroscience, new media, biophysics, materials science, protein folding, nanoelectronics, and wearable computing.

Holy shit.

Just to note, this reminds me of the Lockheed Martin Skunkworks team that supposedly had/ is working/made on projects such as FTL drivers and sorts; using spinning ferromagnetic liquid in a magnetic toroid of sorts.

Heard some other shit they could go through time using several of those FTL engines together and shit.

TDLR: Shit so crazy nobody would believe even if it would exist.

well, this is a first.
