Solidfying the Experience
http://mind-brain.com/forum/index.php?showtopic=4089&view=getlastpost
From a philospohical point ofview it is very difficult for myself to distance from what could be the potential within our very own selves, in regards to what could be possible in the minds capabilties.
I would like to thank you Paul for directing people to the basis of the Lorenz transformation and Minkowskies light cones.
From a cosmological perspective what we can contained in terms of the photon and the graviton in the fifth dimensional expression, brings me back to Ronald Mallets means of travel:) 
Do you see the connection? Each picture frame, is linked back to its respective sites for further consideration.

Alcubierre Warp Drive
An idea for achieving faster-than-light travel suggested by the Mexican theoretical physicist Miguel Alcubierre in 1994.1 It starts from the notion, implicit in Einstein's general theory of relativity, that matter causes the surface of spacetime around it to curve. Alcubierre was interested in the possibility of whether Star Trek's fictional "warp drive" could ever be realized. This led him to search for a valid mathematical description of the gravitational field that would allow a kind of spacetime warp to serve as a means of superluminal propulsion. Alcubierre concluded that a warp drive would be feasible if matter could be arranged so as to expand the spacetime behind a starship (thus pushing the departure point many light-years back) and contract the spacetime in front (bringing the destination closer), while leaving the starship itself in a locally flat region of spacetime bounded by a "warp bubble" that lay between the two distortions. The ship would then surf along in its bubble at an arbitrarily high velocity, pushed forward by the expansion of space at its rear and the contraction of space in front. It could travel faster than light without breaking any physical law because, with respect to the spacetime in its warp bubble, it would be at rest. Also, being locally stationary, the starship and its crew would be immune from any devastatingly high accelerations and decelerations (obviating the need for "inertial dampers"), and from relativistic effects such as time dilation (since the passage of time inside the warp bubble

BACKGROUND ON ESAA
Paul,
Is this Okay? 
In 1994 a Mexican mathematician, Miguel Alcubierre, discovered solutions to Einstein's equations which allow warps in the space-time metric to travel faster than the speed of light. But the proposal Dr. Alcubierre made was unrealistic on three basic grounds:
1.) It required a huge amount of negative energy.
2.) It displayed no casual connection of the ship with the field itself.
3.) The exotic energy states involved violated certain quantum energy conditions like the AWEC.
The ESAA group was founded with the ever present human nature of exploration in mind. The ultimate goal of the group is to physically explore the outer most human reaches, with an emphasis on intellectual exploration to achieve such goals.
ESAA was founded by Fernando Loup, Edward Halerewicz, and David Waite to begin investigations into plausible methods to probe the outer reaches of known science. Fernado Loup a mathematician by trade was interested in exploring mathematical possibilities which may allow for superluminal travel. Edward Halerewicz a beginning physics student was primarily interested in popularizing advanced physical theories to encourage "outside the box thinking." David Waite a seasoned physics student was also interested in exploring the limits of known science and kept radical proposals grounded in real world physics. These three thinkers came together and discussed a recent theory within general relativity which would allow for serious superluiminal discussions.

Warp drive with zero expansion, by José Natário
As everyone knows, Einstein's Relativity forbids all material objects (or even signals) to travel faster than light. What is sometimes ignored is that this is a local statement: speed with respect to an observer can only be defined in a neighborhood of this observer. For instance, it is well known that the universe is expanding, all galaxies (on average) speeding away from each other. An analogy which is particularly well suited is the surface of an expanding balloon, with the galaxies as points on this surface. Although the galaxies are not moving with respect to the balloon's surface, the distance between them is increasing; if they are sufficiently far apart (i.e., if the balloon is large enough), then the distance will increase faster than 300000 kilometers per second. So in a sense they will be moving faster than the speed of light with respect to each other. This is indeed what happens with galaxies at the edge of the visible universe. The "thou shall not travel faster than light" commandment in this analogy simply forbids objects to travel faster than light with respect to the balloon's surface. (Incidentally, this analogy also shows that there is no "center of the universe" where the Big Bang occurred; the Big Bang simply means the epoch where the balloon was very small and very hot - in a sense it happened in all points of space).

SpaceTime Hypersurfing by Michael Szpir
The warp drive envisioned by Alcubierre is made possible by the subleties of Einstein's general theory of relativity. According to Einstein, spacetime (the union of the three dimensions of space with the dimension of time) is not an inert substrate, but rather a dynamical entity that twists and distorts under the influence of concentrations of energy. Alcubierre suggests that it might be possible to exploit this phenomenon to travel from one star to another faster than the speed of light. This could be done by creating a disturbance in spacetime such that the region directly in front of a spaceship is contracted while the region directly behind the spaceship is expanded. This distortion of spacetime would, in effect, propel the spaceship forward like a surfer riding the crest of a breaking wave. At first glance this mechanism would appear to violate Einstein's special theory of relativity, which holds that no object can travel faster than light. Violations of this law lead to causal paradoxes, in which actors in the present can alter their own past. Yet Alcubierre shows that his warp drive does not, in fact, lead to such violations. The reason is that light also travels in spacetime, and is carried along just as the spaceship is. The light beam is still traveling at the speed of light, relative to the spaceship, which itself is not accelerating relative to the spacetime in its immediate vicinity. Although Alcubierre's warp drive does not engender any causal paradoxes, one might still be concerned for a space traveler's welfare. To get to a distant star and back in only moments, the traveler would have to be accelerated at a very large rate, effectively turning him into soup. Or at least this would be true, if not for the fact that accelerations are relative in general relativity.
