Hey, guess what, COCKFAGS? It turns out Graphene can be used to create an Alcubierre drive.

http://www.technologyreview.com/blog/arxiv/25811/

That's right, graphene, the wonder material, can bring us a working warp drive. Is there anything it CAN'T do?!

>But there's another thing that general relativity appears to allow: faster than light travel.

HOLY LOLY!

You now realize that all an alcubierre drive is doing is topologically stretching the manifold of the universe.

>However, Smolyaninov says that subluminal travel is still possible using this method and shows how it ought to be possible to reach speeds of up to a quarter of the speed of light by distorting space in front of and behind the traveller.

Okay, so it's not actually superluminal speeds, but it's possible to use the Alcubierre drive concept.
Fuck. And here I was excited about touchscreens using quantum tunnelling.

>> No.2338822

>>2338805
I don't give a shit if it's subluminal, those are still relativistic speeds and could get us to Alpha Centauri in a reasonable amount of time.

From the article
>His analysis makes for interesting reading. It turns out that faster than light travel travel is not possible inside any physically-realisable metamaterial. That agrees with various analyses of Alcubierre's ideas suggesting that his bubble would be highly unstable and that superluminal travel would be impossible.

Next time read the whole article before making erroneous claims about graphene

It can't be used to create an Alcubierre drive

That is not a scientific paper, that is some article made by some underage kid who watched too much star trek.

The article contains no science at all, and was written by someone with poor logic skills, who loves to jump to shitty conclusions.

Yeah, straight up shota material.

Fuck /sci/. Even the tripfags that used to be cool are starting to think that everything will stay the same and nothing will change because the end is nigh.
Well, except Inurdaes. He still seems willing to try.

>> No.2339229

>>2339049
The OP grossly misrepresented the actual content of the article. Causality violation is only an issue when attempting superluminal speeds, which the drive proposed in the article would not accomplish.

>> No.2339258

>>2339049
The problem of FTL breaking causality can still be circumvented so long as it is impossible for future events to change the past.

The given thought experiment for this is as follows:

You go back in time with a gun to shoot your father, but when you pull the trigger, the gun jams. Or perhaps you shoot the man you think is your father, but it turns out he wasn't, and so on. The universe seems to mysteriously prevent the creation of any paradoxes.

But all that aside. This isn't faster than light travel, this is merely making possible subluminal travel at ludicrous speed.

>>2338707
did you RTFA? NOWHERE in that article is the word graphene. NOWHERE.

>> No.2339296

>>2339258
Another way of putting this is that you have already been in the past, if you will ever succesfully travel into the past. You just haven't gone there yet.

>> No.2339315

>>2339164
Well, I'm no tripfag, but I think this is cool, even if it isn't FTL travel.

I wonder... would this drive be reactionless? Assuming this guy's math checks out, then this is something that the world's space agencies should be jumping on.

Traveling at 25% the speed of light would make traveling around our solar system easy. I mean, it'd be what? Less than a day to reach Pluto? That's ridiculously fast. You could get to Pluto in a starship faster than you can cross the atlantic ocean in a boat.

>> No.2339342

>>2339296
Wouldn't that require a deterministic universe though? Everything's already happened, it's just that we experience it in a linear fashion rather than seeing the whole all at once.

>> No.2339468

>>2339315
No, even at that speed it would take roughly 24 hours to get to Pluto. Sedna would take twenty days.

But still. Damn fast.

OP: A pants-on-head retard who doesn't understand the words "emulate" and "model." Nobody is thinking about building warp drives out of metamaterials. And what ass did OP pull graphene out of?
