so how long until warp speed is a reality?

>> No.5684506

6 years or so

>> No.5684519

Tesla invented it 100 years ago.

>> No.5684515

It already is, it just takes years of build up.

>> No.5684516

Not anytime soon
Take into account that if you achieve speeds near c, you also need to decelerate...also, acceleration can and will kill you.

>> No.5684517

Best guess is never.

>> No.5684521

We need exotic matter first, which... doesn't exist as far as we know.

>> No.5684527

>>5684521

Exotic matter exists... in the heart of collapsed stellar bodies. Not real usable in there, folks.

Unobtainium is really, uh, unobtainable. So it doesn't matter how possible it really is, using that stuff. We can't use that stuff.

Get used to sublight travel. AND PROPERLY ENGINEER IT.

there's some exotic matter under my couch

>>5684516
Warp speed is not actual speed. There would be no acceleration as your vessel is contained within a warped space/time bubble.

c-can I see?

Never.

The good news is: space is incredibly huge, empty, and boring so you're really not missing much. If we really long to visit dead rocks, toxic infernos, or chilly wastelands we can go to the Moon, Venus, or Mars at comfortably sublight speeds.

What? Why would you think that?

>> No.5684546

offtopic but how fast are we going now?

Relative to what?

>> No.5684556

>>5684548
we're spinning around in our galaxy and our galaxy is moving relative to the neighbors we can see

there must be some sort of answer

>> No.5684557

>>5684556
No, there isn't an answer. There's no such thing as absolute motion.

>> No.5684560

>>5684557
so we are moving relative to another galaxy X, say m(sub x). but taking the average of all the m's, does that converge to zero or to another number, or not at all?

>> No.5684579

>>5684560
The fact that the universe is expanding means it doesn't converge. Also it's impossible to measure the all of those speeds at some universal "accuracy" because what looks like a particular speed from the point of view of someone on one side of the Earth will look quite a bit different to somebody on the other side.

>> No.5684594

>>5684560
From what reference frame? You could make the total motion converge to any number <c by changing your reference frame.

>> No.5684604

>>5684521
What was that shit about using negative pressures/densities instead of exotic matter?

>> No.5684634

>>5684594
I'm afraid not. The universe is expanding more or less uniformly in all directions. The further a galaxy is away from you (regardless of reference frame), the faster it tends to be fleeing. There is no convergence.

>> No.5684648

>>5684540

Because the physics says so. True, we have little direct evidence to go on, but nobody with a brain and education thinks that degenerate matter, neutronium and such don't exist.

>> No.5684681

>>5684634
That's not what I was saying. I was saying any "convergence" that might exist could be made to be any velocity you want.

>> No.5684745

>>5684538

The key issue here is that you don't travel from gravity well to gravity well. That's why we don't do it now: It's totally UNECONOMIC.

A real space-borne culture STAYS IN SPACE, inside habitats constructed from asteroidal and cometary materials.

better question is when will an infinite probability drive be fabricated

>> No.5685024

>>5684546
Just remember that you're standing on a planet that's evolving
Revolving at nine hundred miles an hour
That's orbiting at nineteen miles a second, so it's reckoned
A sun that is the source of all our power
The sun, and you and me
And all the stars that you can see
Are moving at a million miles a day
In an outer spiral arm at fourty thousand miles an hour
Of a galaxy we call the Milky Way

Probably the Woodward/Mach Effect.
