Possible warp drive may allow Alpha Centauri to be reached "in a mere two weeks"

The fact that exotic matter would allow for FTL communication is a very good indicator that it can't possibly exist.

False.

A thing can not be perceived if there is no word for it. I now create atabyxium and the problem is solved.

Cup of tea on Iapetus, next week?
 
A warp drive would be nice, but imagine what else we could build with that mythical negative energy. Hovercars! Anti-gravity belts! Spacecrafts launching by simply being repelled by gravity!

I'd gladly give up causality for all that.

Two comments, though:
- The warp drive does violate the generally accepted theory of General Relativity. It is only possible when you extend the theory. Whether that extension is actually realized in the universe remains to be shown.
- That paper is a mess. No matter whether the content is valid or not, the presentation is horrible.
 
In the year 1994, physicists discovered a quirk in the cosmological code. In the decades that followed, these mysterious notions revealed startling new technologies, enabling travel to the furthest stars. The basis for this incredible technology was a force that controlled the very fabric of space and time. They called it the greatest discovery in human history; they called it the Alcubierre Drive. The civilizations of the galaxy call it...

Eh, it kind of depends on whether the speed of light is exceeded locally or not. If the kind of "negative energy" space has higher speed of light than normal space, I don't think it breaks relativistic principles. I am not an expert though.

Quantum entanglement doesn't allow transmission of information, which is why Truronian said "communication". And I'm having a deja vu right now.

Winner is right, I'm rather sure that if space is distorted in a way envisioned by the Alcubierre drive there would be a timelike interval between the interacting spacetime events, preserving causality.

I remember reading that Albucierre's drive could be easily modified to create closed time-like loops, which cause (or were caused by :mischief:) problems for causality. I'll see if I can find a source later.

Yeah yeah. Well, now we just need element zero negative-energy matter and we're in for a very disappointing space child ending. Oh... :cringe:
 
I like the Event Horizon reference.
 
Look, I'm kinda concerned about the long-term implications of CO2 production. Can you imagine what a hassle it would be (eventually) if there're were a few generations of Man that left streams of stretched space everywhere they travelled?
 
This may not happen for a very long time, Star Trek's timetable may be off, but assuming the world lasts long enough, this too will be discovered by scientists.

I think pretty much anything can be discovered. The rate of research increases dramatically as time goes on. A thousand years ago gunpowder didn't exist. Two hundred years ago man could never fly. Fifty years ago man was just learning to leave the atmosphere. We haven't reached Mars yet, but with time we likely will.

Frankly, I'm not so sure its WORTH trying to develop FTL, since I don't believe there is anything else out there in terms of alien life, and I'm not sure we'll ever reach a planet we can live on (Given enough time, of course, technology should fix this problem as well) but I'm sure it'll happen... eventually...

I bet by 2200 we'll have it but who knows?

The people can say all they want, but they'll never be able to say you aren't afraid to state your beliefs concerning things you'd have no way of knowing.
 
El Mac, don't you love how Star Trek already wonders about that?

By the way, Voyager's warp nacelles were movable to prevent "polluting" spacetime in reference to this episode :D

Some things are just plain impossible. So it's not always a question of time or trying hard enough.

:lol: I didn't know that. I just assumed they were trying to look cool with the special effects.

Oh, I make no claim to know. I just don't believe they exist.

How do we know FTL travel, or any other scientific technology, is impossible to discover?

I absolutely adore the contradiction you're portraying.

"How do we know FTL travel is impossible to discover?"

"I don't think aliens exist."

Perhaps the people in this thread don't think FTL travel exists. That's their right, is it not?

Either way, I'm very interested in knowing why you think alien life does not exist in the universe.
 
Oh, I make no claim to know. I just don't believe they exist.

Yes, but shouldn't beliefs be based off what you do know? And right now, all we do know is that there is an indescribable amount of space for life to pop up and thrive.

Evangelical christians have an annoying trait of not understanding much at all about how the world works.

In this case we the completely reasonable question about how we - meaning, a scientifically literate society - claim that FTL travel is impossible. But will he be receptive to the rational reasons on this? Does he understand the essential bedrock discoveries that have been worked out over the past 500 years? Does he know the ways disparate theories of forces, fields, and matter all coalesce into a uniting model of the universe? It's easy to say he doesn't, since he doesn't "believe" in evolution - but should that matter?

I think it does.

Before engaging an evangelical on topics of scientific matters it might be a good idea to first establish which laws of physics, which guidelines of logic, and which axioms they accept. Otherwise you might be wasting your time and his.
 
My belief that aliens don't exist has more to do with how I view the world than it does actual science. There's no real evidence that aliens don't (Or do) exist. Its mainly philosophical and theological.

Regarding science, I'm not sure what the creation/evolution debate has to do with this at all. And I don't really think of myself of "rejecting" any part of science. I just think they are wrong on evolution.

I don't think there's any other discoveries that I explicitly reject other than anything directly related to evolution. I don't THNIK physics qualifies.

In any case, even if you have to use evolution to make your claim for some reason, I'm still interested in the scientific reason why. Since as far as I'm concerned right now given enough time they will likely find a way around any and every problem.
