Interstella travel

So, I've spent ages reading wiki, and the replies to this thread thanks f'that and a friend of mine with an idea or two, and basicaly I've decided I'll take the Alcubierre drive one please, as the most possible, for now anyway, working-title-wise.

There doesn't seem to be any plausible way to even 'cheat' FTL in as a possibility. Previously, like most hacks, I've been content to just say it's all down to some sort of "field thingy, now lets not think any more about that, on with the story".

But I can't help writing 'hard-skiffy', because it bugs me if things aren't as plausable as can be. I'd actually prefer to write some sort of magical realism so I can get on with creating a rollicking-good-yarn, but I always end-up getting bogged down in a quicksand of 'realism' and 'hardness', and the uncertainty of knowlegde I do not have. The stuff produced as a result reads to me abit dry, abit dull, infexible, and drained of imagination.

Anyway, this time I've gone for yer classic 'wharp-field' model where space-time just kind of helpfully contracts directly ahead of the field (pull) and expands directly behind (push), with the vehicle just sort of 'drifting' at the centre of the field, unbothered by all that time-dilation nonsensebuggerfuddle in the universe outside, and in fact not really 'moving' at all. A special whizzymajig is used to generate the phenomenon in the first place using some sort of "invertiving hoo-haar" working as a source of negative energy to power the 'pull' and [mythic-terms]zero-point energy[/mythic-terms] to power the push.

Abit Trekkie but fuckit. It's called an "Alcubierre drive" that.

I imagined vehicles would be fired from some sort of "Alcubierre generator", so it's like the space-craft are fired off from this giant... 'gun' thing. The field perhaps having a certain duration or rate of degradation that translates neatly into range.

Another intersting idea I came across in the useful-tho-not-entirely-reliable wikipedia is the idea of a zone of lower-energy vacuum that carries the vehicle along inside it as it reacts with the higher energy vacuum of the rest of the univese, but I kind of suspect that would be the kind of deeply dangerous universe-eating vacuum-voodoo it's best not to fuck with, and anyway I never did really get my head around all that Gregg Egan type mumbo-jumbo.

Besides, it should be the other way around with higher-energy state vacuum potentially eating and overwhelming lower energy state vacuum depending on stuff to do with Open School, Flat School or Closed Schools of thought. Or something. :confused:

I also invented all by myself in my room late one night a method of infinate acceleration based on a rod of exotic matter where the greater the temperature-difference between one end (A) and the other(B), the greater the force of attraction of End B to End A, and the greater the force of repulsion of End A from End B (was thinking about the problem with women at the time). I decided if such a material were possible it would turn out that the relativistic effects just kind of take care of themselves in a massive accumilated release of "bow-wave" energy upon deceleration or summik (End A heated and End B cooled or something). So it's like the universe just kind of cause/consequences-up a little private relativity-pocket around the vehicle and waves it on through, muttering something about IOU-notes and settling-up accounts on arrival so the vehicle doesn't have to do something silly like accumilate infinate mass or something. Unfortunately I get the impressison that even if this cheat were allowed, an arrival-event would consist of the obliteration of several hundred stars in an all consuming wall of... whatever kind of radiation "bow-wave radiation" would consist of.

So, that's how far I got so far.
 
How about this idea,

Zero Point Computonium Sheaf.

The computonium runs computations using vacuum energy as a power input at the front, temporarily making it lower-energy vacuum, and at the back it outputs the product of its calculations as an exhaust, temporarily creating higher-energy vacuum. It does this at the rate of one operation per yocto-cycle or something.

Thus it scoots along as a kind of zero-point pitch-drive. Maybe it runs additions or multiplications or something, larger results equating to greater differential, it's like... surfin void maaaaan, :cool:

yes, somebody got lost in wiki all a day and has now come back talking complete gibberish, eyes vacant, hair all wild and smelly...
 
I think the only realistic way of traveling the stars is through wormhole technology. I don't think it's possible to go faster than light.
 
Of course, it's always worth remembering that even the best current sci-fi (in terms of hard science) is basically limited by current theory, and if you're being rigorous about it, current widely accepted theories.

Since science can't yet resolve the gravity issue or reconcile the Einsteinian and quantum universes into one theory, and there is still a bundle of stuff that we simply DON'T KNOW, nor do we know all that's possible in the universe to all those nay-sayers on here who are so definitive in their 'it can't be done' statements...In Victorian days they thought that travelling faster than 30 MPH would kill someone, and in the post-war years UK Jet designers thought that travelling faster than Mach 1 was impossible.

Hell, modern science is only just coming up with some kind of observational proofs of dark matter, so coming out and saying 'This is impossible' is not so far off 'All the problems of physics will be solved in the next 10 years' :D
 
I don't know about anybody else, but my point is that to have FTL in science fiction, you have to introduce at least some element of fantasy. The key is I think to do it with discipline. I've seen someone make a distinction between 'handwavium' and 'unobtainium'

In the former case, you're kind of waffling semi-plausibly about 'inertia nullification fields' or something with very flimsy connections to science, whereas in the latter case, say with wormholes, you're a bit closer to the science, because you're sort of saying 'if we had access to vast amounts of exotic material with negative mass and we could manipulate it in such and such ways, then it looks like we could build a wormhole subject to the following constraints'
 
Fair play, I just find it slightly amazing that there can be so much certainty about FTL being impossible (for example) for today and evermore.

Yeah, I agree. Every scientific breakthrough has been 'impossible' righ up until the point that someway is found to do it.

FTL may well be possibe - we just haven't yet figured out a way to acheive it.
 
We're more likely to figure out how to make a few kilos of matter have negative inertial mass and set up a diametric gravity-drive then we are to manufacture two giant nutronium donuts the span of the orbit of Jupiter and set one around another star and then turn em both (mind-bogglingly) "ON" if you ask me.

I like the diametric-drive idea, fits nicely just over the edge of possibility. Got a whole scheme worked out an everything.
 
there's also the idea that if we achieve a society capable of producing technology that powers FTL flight or some shortcut to get around it - will we still want to or need to?

(cf. Alastair Reynold's picture of how alien civilisations find the idea disgusting)
 
I like the Reynolds take on it actually - esp in Redemption Ark when the 4th State experiments go wrong and people just cease to exist in this reality. VERY spooky.

:D FTL Blue Peter stylee...'Here's one we prepared earlier'...

The same could be said about peniccilen (sp?), or TV or whatever. Part of the human condition is a desire to learn, invent, discover and acheive.

and the aliens who literally curl up and die if you even try and talk to them about FTL :D
 
Which Reynolds book was that? I don't remember any of that.:confused: Youre not talking about his two most recent short story collections are you, haven't read them yet.
 
Nope, Redemption Ark - the one where Clavain and the Conjoiners get involved in a race to Delta Pavonis to recover the Hell Class weps from Nostalgia For Infinity...won't say any more, but the Inhibitors kick some serious fucking ass and went to joint equal first in my 'best alien bad guys' with the Borg.

I think this was in Chasm City, it was the part where the Grub is talking about the Grub history of meeting other civilisations, the ones that curled up and died if you mentioned FTL were the Jumper Clowns IIRC

there was a nice solution for faster-than-light communication in there - it's easy - you just make a box that already has all the messages you ever need to receive in it :D

please do not mention anything Star Trek in the same sentence as authors that I like, there's a good chap. ;)

I loved that chase scene in Redemption Ark, but I think the gettaway scene in Excession was mind-blowingly more impressive, when GSV Sleeper Service slips free of it's minder and starts accelerating, and it turns out the cheeky buggers only spent the last few years quietly converting most of it's mass to Engine.

Reading that chapter was like savouring a rare and deliciously expensive treat.
 
That is a fucking great scene. The one against many space battle with the ROU Killing Time is equally good though, I think.

Nah the drones duel in the first chapter was the best for me.
 
that whole book is pure class

I met Iain Banks at a book signing for Look to Windward and asked a really stupid gormless star-struck question - "Do you reckon it's any good?" :D and he looked at me like I'd stood on his foot. Then he asked me which ones I liked best and I said Excession and he looked totally bewildered.
 
Yeah, I think he rates Player of Games and Use Of Weapons as the best Culture books - I'm with you guys on Excession tho...it's the first book that really focuses on the Minds and the level of control they really do have over the Culture (I liken them to Chinese Mandarins, with their plotting etc) and how the popular image of them as benevolent Gods is clearly not true: when Sleeper Service threatens Genar-Hofoen and he's actually shocked that it would threaten his life...
 
If having the occaisional machine-god take advantage of the even more occaisonal human is the price to pay for immortality, FTL and drug glands, then please show me the dotted line on which to sign.
 
:D

Innit. I still look up to the sky every now and again and wish for a GCU to appear and actually make contact, instead of treating Earth like a test lab as they do in State of the Art...
