Hey guys, im currently writing a book and creating a virual technical guide caled the Sky Union, similar to the Terran Trade Authoritys Handbook and various star wars incredible cross section books.
Hopefully, it'll be an open and expansive hard science fiction community devoted to the development of fictional space vessels based what is known within current science and science theory.
Right now, I want your help!
I want to know your suggestions for how a human, space-faring civilisation, 60,000 years from now would travel through space. Theres two sections I want to focus on.

Impluse Drives/Other
Methods such as rocket engines and ion drives for propelling vessels at roughly 400 tons / 800,000 pounds (http://www.theskyunion.com/starfighter.jpg) at up to 4g for short periods of time.

TFL Drives/Extra dimentional
Methods such as hyperspace or warp fields, which something weighing up to 400,000 tons could use to travel faster than light, negating relatavisatic effects such as time dialation and twins paradox!

Your suggestions could and probably will effect my designs, keep them relativly serious with consideration into there fuels, and the more ingenoius/origanal the suggestion, the better.

Good Luck!
 
I sometimes think about this, and I think spaceships in the future need some kind of advances system for fuel. I mean travelling that far just on fuel doesn't make sense, how can they bring enough fuel? So, without an idea, I'd say, think about something that uses very little fuel, or something like that. Otherwise, it just doesn't work, in my opinion. Maybe invent a new energy source or something like that.
 
I'm going to write one of my massive technical exposes on this. If you think it'll scare everybody else off, I'll PM it to you. If it could stimulate others, I'll post. Anyway, it'll take me a while. I'm a slow typist
 
I have only ever written one sci fi story and in it i used portal technology for instantaneous travel. But interstellar travel in space ships used graviton engines. the idea behind them being manipulation of gravitional waves to create mass displacement. by altering a physical objects affect on gravitional fields to negate its weight and funnel that displaced force at points on the eliptical to produce massive amoutns of thrusts. By controlling gravitional displacement waves inertia could be controlled and gravity manipulated. So no acceleration is felt within the bubble of the gravity field. i never try to explain how this is achieved though with current real life research on gravitational fields it isnt so far out there as to seem impossible:)
 
Fuel would be a real problem in space flight when it gets over you need to go in search of it to refill. I was wondering if ZP Energy (Zero point) would be any good since it is everywhere. Maybe you could use that with a energy/matter converter to produce the fuel required.

For proplusion how about a electrogravitic one, antigravity could do a better job than an Ion drive. It can handle the mass and can also be a source of energy on its own making the ships range infinite since it will never run out of energy.

For TFL drives, how about singularity drives or gravity drives visit this site it could be helpful http://www.freewebs.com/spinstate/. I do not know how much you know about this so i am not going to write anything that would be obvious.
 
I wrote a really long reply covering all your points and questions, but then IE screwed it up.
Mark, check this out. Fuel isn't a problem, so long as you know how to use it!
Also engines would only be used for short bursts, with total burn time equaling that of no more than a few hours on the 400ton sized vessels.
http://en.wikipedia.org/wiki/Specific_impulse
The ion drives or its future anestors, (with exust velosities up to 150,000,000 m/s) are my first choice for impluse drive as there the most veristile, they use much less fuel therefore, carry much less fuel, thus needing less fuel... if that makes any sence.

Chris, look forward to it!
Bendoran check out. As I think it sounds similar to what your trying to describe.
http://en.wikipedia.org/wiki/Alcubierre_drive
http://w210.ub.uni-tuebingen.de/dbt/volltexte/2001/240/pdf/09warp.html
I think its my current first choice for TFL systems

Arkangel, ZPE used to excite me, but now many people equate it with cold fusion and many other past fads which have come and gone, its a very interesting energy source though and as for the electrogravitional drive, sounds interesting, any more info?

Well, that all depends on how far you're going and all, doesn't it?
 
Btw, focus on the idea, the brief concept, what it would need to work, how powerful it would be, and the issuses of used them because any technology people 60,000 years from now would be using, would appear like magic to us.
For example, try explaining a how a television would work to a cave man...
 
Electrogravitics is an ongoing research of the US Navy and Airforce once developed it might change the way we fly in air and space. It basically works using electrostatic energy to create a gravitational field around an object. What electrogravitics is really and its science you can go through this declassified report http://www.padrak.com/ine/INE24.html.

This basicaly works by pushing gravity away from behind and sucking in more from the front. Just fastforward the science to 60,000 years and you could really have something that we cant even imagine now.
 
@dreamwalker - cool links, never heard of that before. Obviously i have seen star trek but never heard of that hypothetical propulsion method. my idea is p[ure fiction ofcourse and not backed up by hard science at all. mostly involving a redistriubtion of gravity and force. imagine mass as a measure of displacement. every object with mass causes a displacement wave in proportion to its mass. larger mass bigger wave. Therefore the earths wave is massive compared to a person and so the displacement creates a force that pulls the smaller object toward the larger. manipulation of these fields alter an objects gravity, but mainatins an objects mass. sort of like force = mass X acceleration. so by forcing an objects gravitonal displacment into a bubble of force about it the mass can be reduced and acceleration will become reciprocal to the reduction in mass. so say an object has a gravity displacement which equates to 500tons of force under 1g. by altering its displacement wave the enegery must go somewhere,so as mass decreases, then acceleration increases. if force is directed the object will accelerate. 10% mass = 10g acceleration with no effect within the bubble.

obviously it is total craziness but it sounds good:)
 
i reckon you should use my anti matter stream engines which is an engine powered by the matter stream given off by a quatum singularity (black hole for all you dumb asses out there)


due to the power out put and the purpetual energy you would have fast powerful engine with a infinate amount of fuel.
 
What about the Bussard ram-jet? There's hydrogen everywhere, and at least the engineering looks feasible.
 
anti matter srteam engine? sounds interesting, not sure about the mechanics of it. Is it one of your own inventions or sourced from somewhere else Lore?

Bussard ram jet is just too slow (and ehem, Lame) for what these vessels are going to be doing.
 
My throughts on this are that 60,000 years is too far in the future for me to even guess at what they would be doing but here goes... Some sort of huge sail almost like a parachute slowing a dragster but in pushing it instead and of course much much larger. The sail can take the energy emitted from stars and the solar rays/wind/flux which is the form in which the energy is emitted. Once out of any gravitational field in theory this could then just keep accelerating and acclerating, okay maybe not to the speed of light but at least to somewhere close.

I like the idea of an matter/antimatter drive too, purely because of the amount of energy that could be released in collisions and then used to propel the craft.

Possibly a combination of the two above methods, the matter/antimatter drive for relatively short flights and to get the craft up to speed faster with the solar sail used for large distance travel.

Alternatively assuming that in future man or woman can control or harness the ability to create wormholes and predict where you would emerge then you would not need the ability to travel too fast just "jump" through the wormholes and you could "jump" around space.

Well there you go thats my ideas for just now anyway...
 
Are you proposing just a sail, because as you should no there would be no propelling "wind" in space. Perhaps what you meant is that the sail collects energy or "fuel" for a propelling engine on the back of the craft, of course you would need a large part of the ship to convert solar energy into propelling fuel for the engines. Another method instead of a sail, i think maybe a fusion reactor would work well in its place. as for wormhole jumping, it is possible to detect them but is impossible to predict where they go to, or even for how long the will be open for, being caught in a wormhole when it destabilizes could, propel you into a part of a distant galaxy or complete erasing from existence or history itself. because of the theory that wormholes have the power for time travel as well as space travel, that means that all of time runs through wormholes, which would mean if you where to die there everything that was to ever do with you would seem like it had never existed.

The antimatter stream engine:-



this works by containing a black hole using gravatronic rings then using the matter stream fired out of the black hole centre to propel the ship, rocket, missile what ever. it also needs no fuel as a black hole is self perpetuating. it also 'if connected to a ship' could be used as a generator for the ship as the black hole would be giving out trillions of teraquads of energy.

Am I allowed- oh, anyway,
A micro back hole is not self perpetuating- I won't put the mathematics but the black hole drive used in Clarkes "Imperial Earth" wouldn't have been stable, though he couldn't have known so at the time. A black hole big enough to be stable would be of (at least) planetary mass, which would be extremely difficult to accelerate. But, at any rate this propulsion system (like several others offered) doesn't address the problem of conservation of momentum- energy is available, but for you to go forward, something's got to go backward, and the faster it does so the less you need. Black holes are for fixed instalations, too massive for mobile.
Still, if you've got some antimatter and some water and some good magnetic containment, you can build a very good drive system- a couple of microgrammes of antimatter and a few gallons of wter, project the two so they meet in a powerful electrostatic field, giving us lots of nice energetic plasma (not really steam, but sort of containing all the bits) nice and charged so the magnets can interreact with it and direct it backwards- the only problem (well, apart from minor details like handling antimatter and getting the requisite magnetic field strengths- technical matters) Is how much reaction mass (water) you have to carry, and how much this adds tu your start mass.
 
your quoting from fiction where i actually quote from visable thoeries. and i never said it was a micro black hole its a compact black hole.

as a black hole is a gateway to antimatter space the balck hole is self peptuating as the energy is created through the colision of matter and antimatter. and if you use the theory that matter can not be destroyed it can only be tranferred from one form to another, you come to the conclusion that there is an infinate amount of matter meaning an infinate amount of energy.
 
who ever said a black hole was a a gateway to antimatter space?? hehe:)

and blackholes give off energy, they only grow in size if the mass coming in is greater than their outgoing energy. to maintain one would require a constant stream of matter injected into the blackhole at exactly the right point to maintain its mass and stability. to much and it would grow, too little it would die.
