snip: A research paper has suggested that a warp drive capable of moving a craft at faster than light speed could indeed be possible. The paper, ¿Putting the ¿Warp" into Warp Drive¿ by Gerald Cleaver and Richard Obousy, two Baylor University physicists, suggests that the speed of light could be broken by manipulating the fabric of space to create a bubble that a craft would ride upon.

From Wikipedia, including mathematical formula and physics behind the wrap drive. It also list the difficulties behind the technology. Alcubierre DriveSource: http://en.wikipedia.org/wiki/Alcubierre_driveThe Alcubierre metric, also known as the Alcubierre drive or Warp Drive, is a speculative mathematical model of a spacetime exhibiting features reminiscent of the fictional "warp drive" from Star Trek, which can travel "faster than light" (although not in a local sense - see below). In 1994, the Mexican physicist Miguel Alcubierre proposed a method of stretching space in a wave which would in theory cause the fabric of space ahead of a spacecraft to contract and the space behind it to expand.[1] The ship would ride this wave inside a region known as a warp bubble of flat space. Since the ship is not moving within this bubble, but carried along as the region itself moves, conventional relativistic effects such as time dilation do not apply in the way they would in the case of a ship moving at high velocity through flat spacetime. Also, this method of travel does not actually involve moving faster than light in a local sense, since a light beam within the bubble would still always move faster than the ship; it is only "faster than light" in the sense that, thanks to the contraction of the space in front of it, the ship could reach its destination faster than a light beam restricted to travelling outside the warp bubble. Thus, the Alcubierre drive does not contradict the conventional claim that relativity forbids a slower-than-light object to accelerate to faster-than-light speeds. However, there are no known methods to create such a warp bubble in a region that does not already contain one, or to leave the bubble once inside it, so the Alcubierre drive remains a theoretical concept at this time. |

PDF copy of the research paper: "Putting the "Warp" into Warp Drive" by Richard K Obousy and Gerald Cleaver Baylor University, Waco, Texas, 76706, USA (Dated: July 15, 2008) Source: http://arxiv.org/PS_cache/arxiv/pdf/0807/0807.1957v2.pdfAbstractOver the last decade, there has been a respectable level of scienti c interest regarding the concept of a `warp drive'. This is a hypothetical propulsion device that could theoretically circumvent the traditional limitations of special relativity which restricts spacecraft to sub-light velocities. Any breakthrough in this eld would revolutionize space exploration and open the doorway to interstellar travel. This article discusses a novel approach to generating the `warp bubble' necessary for such propulsion; the mathematical details of this theory are discussed in an article published in the Journal of the British Interpanetary Society [1]. The theory is based on some of the exciting predictions coming out of string theory and it is the aim of this article to introduce the warp drive idea from a non-mathematical perspective that should be accessible to a wide range of readers. |

PDF copy of the research paper: "Supersymmetry Breaking Casimir Warp Drive" by Richard K Obousy Baylor University, Waco, Texas, 76706, USA (Dated: July 15, 2008) Source: http://arxiv.org/PS_cache/gr-qc/pdf/0512/0512152v1.pdfWithin the framework of brane-world models it is possible to account for the cosmological constant by assuming supersymmetry is broken on the 3-brane but preserved in the bulk. An effective Casimir energy is induced on the brane due to the boundary conditions imposed on the compactified extra dimensions. It will be demonstrated that modification of these boundary conditions allows a spacecraft to travel at any desired speed due to a local adjustment of the cosmological constant which effectively contracts/expands space-time in the front/rear of the ship resulting in motion potentially faster than the speed of light as seen by observers outside the disturbance. |

PDF copy of research paper: Original paper of Alcubierre Drive (Warp Drive) The warp drive: hyper-fast travel within general relativity. by Miguel Alcubierre Department of Physics and Astronomy, University of Wales, College of Cardi , P.O. Box 913, Cardi CF1 3YB, UK. 5 Sept 2000 http://members.shaw.ca/mike.anderton/WarpDrive.pdfAbstractIt is shown how, within the framework of general relativity and without the introduction of wormholes, it is possible to modify a spacetime in a way that allows a spaceship to travel with an arbitrarily large speed. By a purely local expansion of spacetime behind the spaceship and an opposite contraction in front of it, motion faster than the speed of light as seen by observers outside the disturbed region is possible. The resulting distortion is reminiscent of the \warp drive" of science ction. However, just as it happens with wormholes, exotic matter will be needed in order to generate a distortion of spacetime like the one discussed here. |

Alcubierre warp drive spacetimeF. Loup Royal Sun Alliance Avenida Duque De Avila 141 2 Andar 1050 Lisbon Portugal D. Waite Modern Relativity E. Halerewicz, Jr. Lincoln Land Community College 5250 Shepherd Road, Springfield, IL 62794 USA July 29, 2001 http://arxiv.org/PS_cache/gr-qc/pdf/0107/0107097v2.pdfAbstractIt can be shown that negative energy requirements within the Alcubierre spacetime can be greatly reduced when one introduces a lapse function into the Einstein tensor. Thereby reducing the negative energy requirements of the warp drive spacetime arbitrarily as a function of A(ct, p). With this function new quantum inequality restrictions are investigated in a general form. Finally a pseudo method for controlling a warp bubble at a velocity greater than that of light is presented. |

This is all pretty old stuff, and you probably could have posted it in one of dryson's many threads on warp drives.
In any event, these papers and theories are pretty off base.

Personally, I wouldn't want to do it, but only because I feel too unqualified to do so!
A plasma drive, or better yet, a fusion drive (and just pushing it, an antimatter enhanced fusion drive) would be better suited with my desires.
But then again, my personal sites for space exploration focus mainly on the solar system itself.

So, pound the solar system four times?  Seriously, there is still much to find, or at least, to see. I'd love to climb the mountains on Mars, walk the slushy dirt of Titan, take a look beneath the ice of Europa, watch the double sunrise that takes place on Mercury, and see a liquid nitrogen geyser on Triton. And that's just the beginning. |

Yeah, probably a good start before you go galavanting off to Andromeda or something.
I'll meet ya at Phobos...
