One of the main points used by debunkers of Aliens having ever reached Earth is that they are just too far away, that it would take millions of light
years to reach us and that nothing can ever travel faster than the speed of light.
However a blockbuster new paper, to be published in the Journal of the British Interplanetary Society early 2008, changes all of that by stating that
infact the laws of physics do allow such a device if certain methods to use these laws are employed to propell it.

Full science paper; xxx.lanl.gov...
Certain classes of higher dimensional models suggest that the Casimir effect is a candidate for the cosmological constant. In this paper we
demonstrate that a sufficiently advanced civilization could, in principal, manipulate the radius of the extra dimension to locally adjust the value of
the cosmological constant. This adjustment could be tuned to generate an expansion/contraction of spacetime around a spacecraft creating an exotic
form of field-propulsion. Due to the fact that spacetime expansion itself is not restricted by relativity, a faster-than-light ‘warp drive’ could
be created. Calculations of the energy requirements of such a drive are performed and an ‘ultimate’ speed limit, based on the Planckian limits on
the size of the extra dimensions is found.
They go on using elementary physics to explain how this speed is possible. Basically they propose that by creating a contraction in space-time
geometry infront of the vehicle, and an expansion behind the vehicle, should produce sufficient motion to far exceed the speed of light, without
actually breaking any of the laws of physics.
The basic idea is to formulate a solution to Einstein’s equations whereby a warp bubble is driven by a local expansion of spacetime behind the
bubble and a contraction ahead of the bubble. The aim of this paper is to suggest that a warp bubble could be generated using ideas and mathematics
from quantum field theory, and to hypothesize how such a bubble could be created by a sufficiently advanced technology. [.......]
[......]We have proposed that a sufficiently advanced civilization could utilize this relation to generate a localized expansion/contraction of
spacetime creating a ‘warp bubble’ in which to travel at arbitrarily high velocities. One vital aspect of future research would be how to locally
manipulate an extra dimension. String theory suggests that dimensions are globally held compact by strings wrapping around them [5], [8]. If this is
indeed the case, then it may be possible to even locally increase or decrease the string tension, or even locally counter the effects of some string
winding modes. This would achieve the desired effect of changing the size of the extra dimensions which would lead to propulsion under this model. It
would thus be prudent to research this area further and perform calculations as to the energies required to affect an extra dimension and to try and
relate this energy to the acceleration a spacecraft might experience.
This work follows on from the cutting edge research of Francisco Lobo, Matt Visser and Michael Morris into the plausibility of wormholes, and faster
than light travel, all within the laws of physics;

Not a surprise...to me.
Ignorant people will say that aliens could never reach us because it's too far-well we only created the airplane a century ago, what will we find out
next century. As time goes on, we will find new theories and then 'newer' ones to say the old theories are wrong.
Don't just think a short-term or even a theory that has been around for decades is absolutely true, if you think we know all there is or even a lot
about the universe, then congratulations, you receive the gold medal for Ignorance.

I think that modern science has forgotten the very definition of the word theory, which means that if a better theory comes along, you have to
replace the old theory. Theory's are different from laws of physics, which are definitive. We're still stuck in Einsteinian relativistic
dogma way back from the 1930's, and things have pretty much stayed there, with no new theories being accepted over Einsteins for over seventy
years.
Even using Einsteins relativity this paper has managed to get around his light speed barrier by creating a contraction in space time. We can nearly do
it now with particle accelorators, the chances of a far advanced civilization being able to master it is very likely.

oh my!!!!!!!! ETs travel faster then light. Well where are they?
Not even a signal from space. Silence.No alien artifacts. Fermi paradox states that our size galaxy could be colonized in 50 million years without
faster then light travel.And our galaxy is half the age of the big bang.It should have been colonized thousands of times over.So where are they?Thats
the question you should be trying to solve instead of calling people ignorant.Its fun to think good old earth is the center of the universe and ETs
are all around us,but there is no reason for them to be here.Any space travel to the stars will be done by humans,not ghosts. spirits or aliens or
whatever you believe. Happy Hollidays!!!!!!!!!!!!

I'm still on the side that anything we can conceive, we will eventually achieve.
Newtons laws said man cannot fly, 104 years ago today the wright brothers flew. They didn't prove Newton wrong, they just discovered a different set
of laws, the laws of aerodynamics. We still have plenty to learn and eventually, we'll zip thru the universe like it's our own hometown.
Scary, ain't it

Yeah it is but at the LANL site you need to come in the front door Hot linking there will get you 'noticed' But the first link is the same just
click on pdf on the right
But that archive is the public archive of LANL so hot link works

Thanks for this... I had some of the warp drive papers before but when I posted the links at ATS they moved them LOL Imagine all the ATS 'ers
hitting that site at once sends up flags..
Got them all though Thanks for the find
Oh and a word to the wise... don't try to back track urls there... its NOT healthy

"Any space travel to the stars will be done by humans,not ghosts. spirits or aliens or whatever you believe."
I'm on hold right now with Websters. They are considering letting me use the above poster's quote as the definition of ignorance.
Really though, the most obvious, not the most convenient to your way of life, is usually the truth. Alien have been visiting us for years. Every type
of person on Earth has said it the only ones who say otherwise is the US gov. which has been proven in the past to lie. Just like in 30 years people
will know the truth about the current admin. History repeats itself and truths never stay hidden. Most people who live now are descended from the
people who thought the world was flat.

People have been saying this for how many years? 60 or so? I mean didn't we see this in star trek in the 60's and in sci-fi books prior? so just
because some scientist say it's possible, it's true now? I mean why is it that we trust some guy who went to school and did some studies but when a
poet, musician or just a regular says it, he's nuts.

That paper doesn't say it's possible, it just speculates that it might be.
It's just a theory, folks.

A lot of people also use the theory of relativity as an excuse that aliens would not visit us simply because by the time they get here millions of
years would have already passed on earth and their home planet relative to their time. They would stay young while people they are close to on their
home planet would age.
How do we know with 100% certainty we can't bend the fabric of spacetime or break the laws of physics? How do we know time travel is not possible
which could be used to reverse the effects of relativity if conventional means of travel were used?
These physics theories are just… well… theories. And even though we have laws of physics that are not theories, we can't prove that the laws can
not be broken or bent, just like the laws of a country.

Even NASA is beggining to accept that faster than light 'warp drive' is actually possible within the laws of physics. They placed it in the
speculation category, but i would say that it is far into the science category by now with all the research into supluminal travel being done recently
in verious tests on earth. www.nasa.gov...
You can be sure NASA is not letting on everthing they know as usual, so i would guess that arrow belongs more between the science and technology part
than the speculation part. Twenty years ago they would'nt have even considered it.
This is another conference that was held at the respected interplanetary society;
www.bis-spaceflight.com...
This suggested the possibility of effectively enabling a vehicle to move across enormous stellar distances in a short transit time, allowing the
warp bubble interior as well as a vehicle located within to be moved through spacetime faster than the speed of light with respect to the distant
universe. That is to say, within the warp field the speed of light limit has been raised so that locally the vehicle does not violate the central
tenet of special relativity.
Since this seminal paper around 50 publications have appeared internationally on the topic demonstrating that academic interest in the ‘warp
drive’ proposal is growing. In the first decade of research several technical physics obstacles have been identified towards making the warp drive a
realistic proposal for interstellar travel. In particular, calculations show that physically enormous and unobtainable amounts of negative energy are
required to generate the desired geometrical warpage. In an effort to generate interest in solving some of the technical problems a symposium is being
organised with the intention of focussing on four main themes: The Current Status of the Warp Drive Proposal; Quantum Field Constraints; Photon
Propagation through the Warp Field; Alternative Faster than Light Drives. Where the latter may be based upon alternative versions of Einstein’s
gravity such as Brans-Dicke theory or Yilmaz theory, or based upon alternative suggestions for interstellar travel such as the Krasnikov tube and
wormholes.

What relevance has that got do with the OP?, which was specifically about the possibility of faster than light travel, which makes the possibility of
them reaching us far more likely.

Not even a signal from space? I'm not sure why an advanced civilazation would be bothered about sending us radio signals when they could likely
travel straight here instantly if they wanted to. Also there have actually been many signals that are unexplained from space, and also plenty of
evidence of life outside of our own planet. space.newscientist.com...
Top 10: Controversial pieces of evidence for extraterrestrial life
1. 1976, The Viking Mars landers detect chemical signatures indicative of life
2. 1977, The unexplained extraterrestrial "Wow!" signal is detected by an Ohio State University radio telescope
3. 1996, Martian "fossils" are discovered in meteorite ALH80041 from Antarctica
4. 2001, A more rigorous estimate of the "Drake equation" suggests that our galaxy may contain hundreds of thousands of life-bearing planets
5. 2001, The red tinge of Jupiter's moon Europa proposed to be due to frozen bits of bacteria, which also helps explain the mysterious infrared
signal it gives off
6. 2002, Russian scientists argue that a mysterious radiation-proof microbe may have evolved on Mars
7. 2002, Chemical hints of life are found in old data from Venus probes and landers. Could microbes exist in Venusian clouds?
8. 2003, Sulphur traces on Jupiter's moon Europa may be the waste products of underground bacterial colonies
9. 2004, Methane in the Martian atmosphere hints at microbial metabolism
10. 2004, A mysterious radio signal is received by the SETI project on three occasions - from the same region of space

Yes it should have been colonized many times over according to many well established theories. Thankyou for clearing that up. The Starchild skull
(which has been DNA tested) is good evidence of ancient aliens. Also the horned skull, the huge Trilithon at Baalbeck, and various other historical
anomalies support ancient aliens visiting Earth. Add to that the millions and millions of UFO sightings every year and the hundreds of military
officials that have now gone public, that makes your statement that there is no evidence of Aliens visiting Earth truly ridiculous.

Lambda-based ‘warping’ allows one to travel “faster than the speed of light” because it is moving the space/time that an object exists within
as opposed to moving through space/time directly. So, no, it is not scientifically impossible, and it does not interfere with special relativity one
bit. No laws are being broken per se, they just being moved around a little.
Unfortunately, it still has its problems. One is that you need negative mass energy. (That’s A LOT of energy!) And we are talking several solar
masses of the stuff, which makes your guess about as good as mine concerning how an advanced race could obtain something like this.
Second, there is the numerical anomaly we encounter with signals taking an INFINITE AMOUNT OF TIME to reach the outer boundary of the “bubble.”
There are also a number of quantum energy conditions that become violated at a certain point.
Most theorists state that ‘exotic matter’ is absolutely required to create these outrageous space/time bubbles, which eliminates any and all forms
of regular mass-based energy we are familiar with. Using lambda is to manipulate the cosmological constant locally somehow, according to this paper;
to create this bubble they claim can get around the problem of having to use exotic matter. Unfortunately, lambda may BE ‘exotic matter’ whether
we like it or not.

i agree ---not only is speed faster than light possible for aliens--speed as fast as a thought is possible----for them to think is to be
there---------but some dont have to come very far anyway-----because they are already here-----cloaked/invisible----just as the brits have recently
demonstrated possible with an invisible 60 ton tank and as nasa film shows huge ufo's that look like eyes coming out of nowhere and then disappearing
back to ?nowhere from the space shuttle missions with the astronaut videos taken out thru the windows in their cockpits.

Unless above the speed of light of in a slightly different dimension (which you'd need to avoid planets and rocks etc in space at superluminal
speeds) you wouldn't hit anything. Only problem might be stopping inside a planet or too close to a a star. It's just going to happen, one way or
another... space pirates. Probably already exist. Roving marauders, looking for signals from stupid civilisations to conquer and hot on their trail is
the galactic police/UN.
People think a one world government is bad, but maybe that is a condition of us being allowed to enter open talks with extraterrestrials?

I swear that about 15 years ago I read an explanation of how the warp drive featured in Star Trek operates exactly how you've described here. That
bit about locally manipulating extra dimensions sounds familiar, too. I'm pretty sure that there is book out there that explains the physics of Star
Trek that touches on these same ideas in reference to warp drive technology. Wow!

Well Scotty would be proud!! What's the betting that in a 100 years or so we will be hearing the famous words of frustration " The Engines canna
take it anymore Captain!". I think this is an exciting bit of news and we should embrace it. After all Humanity will need to get of this rock fairly
soon and settle down on other planets if we are to survive, particularly considering the quite considerable damage overpopulation is doing to this
one.
