Interlestear travel/ slipspace drive

[XxAssasiNxX]

Well if you don't know what slipspace travel is it was used in the halo series as a form of FTL travel and is based on a real thory that actually has a lot of promise in. Well basically it means ripping a wormhole or something in space and entering a different dimension of space called (subspace) this realm can make it easier to travel from point a to b because everything moves faster in it. I'm not an expert but this is what I've heard. We still don't know if it exists or if the wormhole would just collapse. But I'm not worried because I know we're not advanced enough to comprehend this sort of stuff. We only started understanding space in the last 50 years or so. Give it another 250 years I think well have a better understanding by then.

So in arond 300 years I think we will have FTL speed possible:D
Reason why is because how much the human race has advanced in this 10 years of the 21st century. In 10 years we achieved so much and in the last 100 years we worked out so much shit. It still seems impossible. So in 250 years or so I think we will have intelstear travel.
Another problem is anti gravity.

We need to work out this if we want to have huge starships or have earth like gravity in ships. Actually it wouldn't work without it. That's beyond anything of our technologies in this century.

What are you're thoughts on this stuff. I just thought I post something that's really on my mind :D

I thought this was time travel for a second until I read it carefully. XD

Scientists are still trying to figure out how to even locate black holes/worm holes. Once they figure that out then we can start thinking about interstellar travel.
I do believe though, that we aren't that far off from figuring out a more effective way of space travel. 250 - 300 years sounds pretty accurate.
Personally i hope i live to see the day when this shit is mainstreamed and used in our world. That would be amazing.

The main problem with FTL is that we aren't even sure that it is remotely possible. Current physics clearly point at the speed of light in the void as an absolute limit you cannot cross (and cannot even hope to reach, actually), regardless of your technological level. Parallel dimensions, crossable wormholes, or gravitational warp are currently only theorical science-fiction concepts.

I'm glad a topic like this pops up every now and then here.
FTL is an interesting concept, yet from a special relativistic point of view you can't really travel through our space faster than light. The subspace, hyperspace, or slipspace concept is interesting, yet we have no evidence of that kind of dimension actually existing. When physicists think of FTL travel, the essential goal is not to breach the impossible speed of light limit, but create a shortcut through space and time in which we're traveling.
Often times futuristic visionaries propose models of warp drives, specifically Alcubierre drives, which use controlled doses of energy to contract spacetime in front of the ship and expand behind it. So the spaceship would not really move through spacetime, but a wave of spacetime would carry it. This is sometimes referred to as the "reactionless drive" which is a propulsion system that does not use any kind of chemical, nuclear or matter-antimatter reaction, just pure spacetime manipulation. Possibly the warp drive would reach superluminal speeds. Yet the proposed problems say, that such manipulation of spacetime would cause unpleasant effects to the travellers inside the surfing bubble of spacetime. For subluminal travel the frontal contraction of spacetime would not create a naked singularity (a black hole singularity without the event horizon). But for FTL energies would have to be concentrated as to create one. This would result in severe tidal forces at the curvature, but that doesn't seem to be the problem for the ship inside the bubble at safe distance from the severe curvature. If you are familiar with black hole evaporation through Hawking radiation, you might reconcile that vacuum energy gets released in a form of particles that radiate away the black hole's mass/energy. The same thing would happen in the warp curvature with naked singularity. Instead of dissapating into outer space, particles and radiation would cumulate inside the spacetime bubble, quickly increasing the energy density, literally cooking the whole ship and its crew to a soup of elementary particles. Nothing would be left. So this is not a good alternative, although an effective one for subluminal travel.
In my opinion traversable wormholes, based on concepts of general relativity's constructs - Einstein-Rosen bridge are the best alternative. And for FTL apparently the only one. You see, I've read a lot of scientific papers and discussions on this issue and it turns out that for an effective production of wormholes one would have to gather a sufficient amount of "negative energy" which is ,in physical terms, the gravitational potential that balances out the positive energy from matter and radiation, to keep the mouths of a wormhole open. When a wormhole is created through high energetic bursts of particle collisions, the key is to create a tunnel through two distinct points in spacetime. If we managed to create a stable wormhole on tiny scales, reaching up to the diameters of atomic nuclei, we could then build up its mass and expand it. Both mouths would have to be created at the same time, separated only by a planck frame of distance to form. After creation they will remain connected unless an instability occurs. Both ends of the wormhole would have to be transported at speeds not exceeding 0.5c (because of special relativistic effects they will become displaced in time, which is not a good thing. Nature likes to prevent time travel to the past, so approaching such speeds would lead to collapse.). Then they can be created in different places, distributed across colonized systems and form a net. The key thing is that for a solar-mass wormhole the mouth would have to be far away from any massive object in a radius of approx. 300AU (45bn km). This means that wormhole mouths would have to be far beyond the solar systems they connect, yet not that far. It would take several weeks to reach them, the transit between mouths will take about 5 days and then few more weeks to reach the desired planet in the next solar system. It's not as fast as the warp drive in Star Trek or Hyperspace in Star Wars, or the Halo slipspace, but it still shortens the journey of decades of subluminal travel to a few months.
Such technology is beyond our reach, stretching our abilities to perhaps millenia into the future. So we will have to be satisfied with subluminal travel and transport colonists as human popsicles in cryostasis. People who see many sci-fi movies and games often idealize the view of space travel. Essentially, it is a very dangerous thing. We are not fit for space, even though we might have advancing technologies. We must slowly adapt to space travel, possibly as a necessary route for our future evolution. So should our knowledge and technology. But believe me, future will not look like adventurous science fiction with classic space dogfights and explosions. Space is different. :D It certainly is no place to fly around in a dogfight like back on Earth in air battles. If there will be any space warfare in the future, it will have to be highly automatized and you would not even see the enemy that you're attacking, because space is huge and things are really far away from each other. By those means, a tactical advantage might be the ability to detect the enemy at greater distance, dispensing effective firepower in a form of homing missiles or practically invisible lasers and particle beams or perhaps in the more distant future, through spacetime manipulation, the ships could use weaponry that stretches and contracts spacetime at high energies, literally tearing apart enemy ships. The problem still rests in the precision on such long distances with moving targets that can reach really high velocities. One might think that for the sake of effectiveness for very small amount of input of resources and energy, future warfare will still rest on the good old fasioned kinetic energy (taking it to considerable power, of course). We might just end up changing trajectories of asteroids to parabolic acceleration around massive planets or stars and then shooting them at high velocities to the enemy. Essentially we'll end up throwing stones at each other again :)
