>How NASA might build its very first warp drive "My early results suggested I had discovered something that was in the math all along," he recalled. "I suddenly realized that if you made the thickness of the negative vacuum energy ring larger — like shifting from a belt shape to a donut shape — and oscillate the warp bubble, you can greatly reduce the energy required — perhaps making the idea plausible." White had adjusted the shape of Alcubierre's ring which surrounded the spheroid from something that was a flat halo to something that was thicker and curvier.

I'm a very skeptical person, but space travel makes me wet as a river.

So I'm very hopeful a breakthrough with this comes out.
How awesome would it be to be apart of a colony to another system in your lifetime?

Strange matter isn't strange enough. You need negative matter, matter with negative energy density.

>> No.5395184

We'll have to send monkeys then... a pair of monkeys that can procreate and pilot the probes. And the probe that gets left behind they can live on so their children and children children can pilot the probe for generations to come.

>> No.5395185

The article title is bunk, what is being constructed is not a warp drive. The problem still remains that there is no negative matter. No one can say if that will happen in your lifetime because no one knows if it exists.

Space travel sucks.

We should be working on teleportation first, which *should* work the same regardless of distance, then just put teleporters in our space craft, so we only need to fly somewhere once. We wouldn't need to worry about fuel capacity either if we could just keep teleporting more onto the ship, which would be a lot lighter without a crew, life-support or any of that other crap.

That is, if we couldn't just teleport straight to another location without some kind of receiver.

While there alternatives to using exotic matter, it's only a matter of time before we are able to produce it. Simply because we don't have the technology to produce something now doesn't mean we won't in the future.

A few decades ago we didn't even know antimatter existed, but now we are producing antimatter for experiments. There is going tio come a time when we find a way to manufacture large quantities of antimatter, but just because we can't do it yet doesn't mean we will never be able to do it.

Could the effects of exotic matter be replicated through other technological means, such as anti-gravity technology?

you don't need ''exotic matter''
exotic matter is simply the answer when looking at the problem from solely standard model view, while the standard model clearly isn't enough in terms of quantum mechanics and gutantum gravity

If we had anti gravity technology, i suspect we wouldn't need exotic matter.
Either that, or we'd need exotic matter to develop anti gravity in the first place

I cant find the article, but I recall something about rotating super conductors doing something with gravity, though it was still relatively weak.
