[QUOTE=Mudbone;21656290]So just how could we go about bending the universe. How do you physically do it?[/QUOTE]
I would guess ridiculously large amounts of matter might bend spacetime sufficiently enough to be noticeable at the universal scale.
[QUOTE=Eudoxia;21656469]That's why I said nobody knows yet, because negative energy adn such is still theoretical. Once we find it, we should know how.
There could be some unexpected things, like negative mass adn such not working because we assume it has negative inertia, but I think that's for a different kind of propulsion, not the Alcubierre drive.[/QUOTE]
Well, the point being is that we DO know, we just need materials we don't have.

Well, certain black holes can punch a hole in space-time so
also neutronium is p. sexy shit for bending space time
[QUOTE=Quo Vadi;21656376]Yes we do, we just need unthinkable amounts of negative energy and we're not positive it would work because it's hypothetical.[/QUOTE]
There is actually a solution that only requires a few milligrams of [URL="http://en.wikipedia.org/wiki/Exotic_matter"]exotic matter[/URL] in order to achieve the effect.
[QUOTE=Wikipedia]Chris Van Den Broeck, in 1999, has tried to address the potential issues.[10] By contracting the 3+1 dimensional surface area of the 'bubble' being transported by the drive, while at the same time expanding the 3 dimensional volume contained inside, Van Den Broeck was able to reduce the total energy needed to transport small atoms to less than 3 solar masses. Later, by slightly modifying the Van Den Broeck metric, Krasnikov reduced the necessary total amount of negative energy to a few milligrams.[2][/QUOTE]

Of course, exotic matter has yet to be found.

A black hole and very very massive things can bend spacetime, but IIRC they can only compress it. Expanding it would require something like a set of very massive stars placed in a circle around a point, or some shit.

Well, plus according to the source it's only viable for a few atoms...?
Still an enormous breakthrough if exotic matter is ever created/found
Your forgetting the geller field.

Yeah, just shows that in theory we can reduce the energy needed, so we *could* find a way to make it working.
The discovery of exotic matter would probably be one of the biggest achievements of mankind so far.

I hope you know Warhammer was bullshitting you about that, there's no scientific theory similar to it.

To be honest, I looked up "Holtzman effect" after reading Dune.

You're an Erepublik player, of course I do.
mr = m0 /sqrt(1 - v^2/c^2)
Calculating mass increase with velocity. The problem, is that if you reach the speed of light you divide by zero, which causes an infinite mass (Which are pretty hard to move!)

Negative energy has been shown practical, if you define the energy of the vacuum as zero.
Actual, the vacuum is full of infinite much zero-point-energy. But you can create spaces, where a fraction of this energy at a specific frequency doesn't fit in (Casimir Effect). So if the Vacuum was defined as zero energy, then the Casimir Effect describes negative Energy.
I has been measured and proven btw.

I didn't understand much about that post, TBH, except for vacuums being full of lots of zero point energy (which is p. cool)
Also, apparently, two plates placed in a perfect vacuum produce negative energy...?

IIRC, the casimir effect and vacuum energy can be explained through the concept of "virtual" particles, a matter and anti-matter pair which appear from vacuum for a tiny amount of time then instantly annihilate.

Oh. Right. Didn't I hear something about black holes separating these before they can autoannihilate in a lecture once?
So, couldn't you produce antimatter from that with a vacuum and a very strong source of gravity?
I think there's also a theory where a black hole eats one of these virtual particles creating an imbalance too.

I think that's what causes the Hawking radiation, but I'd need to check.
[QUOTE=rosthouse;21657101]I think that's what causes the Hawking radiation, but I'd need to check.[/QUOTE]
Hawking radiation creates a particle and an antiparticle, and one of them falls into the black hole and the other one escapes? I think it was you who said that once.
Question. What defines a vacuum? Aren't there relatively (compared to atomic sizes) enormous amounts of space in the universe between atoms (without matter), and so wouldn't there be matter-antimatter annihilation go on everywhere in small amounts?
Or does a vacuum have to have a predetermined space or barrier before it becomes a vacuum?

Oh right, it's getting late here :v: And I just checked it again, it still is the Hawking radiation :wink:
(To be correct, the particles are not created by the Hawking radiation, the surviving particle is the actual radiation)
We don't need no pansy fucking warp drive, we just need to discover mass relays.
