realistically, when can we hope to achieve this /sci/?

>>8886467
Isn't everything time traveling to the future?

>>8886467
Never. By the time it became technologically feasible, if ever, quantum gravity will likely be solved to the extent needed to design something much better.

>>8886482
nice comment, retard.

>Solving quantum gravity
Hey >>8886490, you quoted the wrong post.

>>8886490
(you)

after we manage to create more negative mass than there is mass in the universe, prevent the inside of the warp bubble from heating up to a billion kelvins, construct a wall almost as thin as the planck length, and prevent the arrival destination from being absolutely obliterated.

correct, but I still have hope, these are just technical obstructions to overcome.
To the stars! ;)

When we get substantial quantities of negative energy

>>8886953
the fuq is negative energy?

Chakras?

about 10-20 million years.

>>8886467

HA
Even the improved version of this thing would supposedly require the annihilation of several tons of matter to provide enough energy. I don't think several times the yearly energy output of all human civilization counts as 'low input power'.

>>8886467
>Possible w/o Exotic Materials: YES
isn't negative energy/mass an exotic material?

>>8886486
By then I would assume too that we've moved on to quantum skeletons

>>8886467
recently a bunch of researchers confirmed the existence of negative mass so it might be nearer than we expected it to be

Fire had negative mass you fucking autists.
Just put fire on something and watch how it gets lighter.

i am hoping to god that the cassimir effect has macro scale effects when you get a material made almost entirely of extremely fine lattice, because that's like the only way you're getting anything like negative energy that concentrated
also there's the whole "compressing spacetime on such a small scale" problem

i mean, even if you don't break C with it, it's still super handy at sub 10% C because you don't experience inertia inside the bubble, meaning there's no need to accelerate or decelerate for a journey, saving a lot of time on trips inside the solar system over traditional rockets.

AND it'd be an electric-only, reaction-less drive

>>8886467
never

>>8886467
there was a student at Sydney Uni that did the math to do with the accumulation of heavy particles I think it was. His maths pointed out that when you arrived at, lets say Alpha Centauri, the energy released would destroy the destination.

>>8886467
Perhaps by being able to link 2 points in space without preparation?

>>8886467
how can you achieve superluminal speeds without moving backwards in time?

how do we know it's technically viable? it looks pretty abstract
