Before we
jump into this, you should know that a number of scientists are currently
researching the feasibility of warp drive (and EMdrive and a number of other
modes of faster than light travel); however, most think that such forms of
space travel simply aren’t viable, thanks to the fundamental physics of our
universe.
So although
part of this article is simply, “Oh my gosh, look at this amazing design,”
that’s not the entire point. To that end, let’s take a moment to break this all
down a bit so we have an understanding of what exactly is being proposed in
relation to warp drive, and why it is met with such skepticism, before we get a
bit too carried away…
In 1994,
physicist Miguel Alcubierre proposed a new kind of technology that would allow
us to travel 10 times faster than the speed of light without actually breaking
the speed of light. That seems a little contradictory, doesn’t it? After all,
we’ve been told time and again that light is the universal speed limit –
nothing in the cosmos can travel faster than it (much less 10 times faster) and
herein lies the key to the Alcubierre drive: When you use it, you aren’t
actually moving through space.
This
technology would not actually propel the ship to speeds exceeding light;
instead, it uses the deformation of spacetime permitted by General Relativity
to warp the universe around the vessel.
Essentially, when the drive is activated the spacetime behind expands, while in
the front it contracts. In this respect, the path taken becomes a time-like
free-fall.
Alcubierre’s
ideas have lead to a number of interesting thought experiments in quantum field
theory; however, as mentioned above, most scientists think that the technology
will never actually work. When you think about it, that kind of makes sense.
Obviously, warping space requires a lot of mass and energy, and ensuring that
the space where you are located isn’t warped is tricky business. Indeed, the
proposition was mostly just a thought experiment when it was first proposed –
not something Alcubierre thought was actually viable technology.
As physicist
Sean Carroll notes:
In short, it requires negative energy densities, which can’t be strictly disproven but are probably unrealistic; the total amount of energy is likely to be equivalent to the mass-energy of an astrophysical body; and the gravitational fields produced would likely rip any ship to shreds. My personal estimate of the likelihood we will ever be able to build a “warp drive” is much less than 1%. And the chances it will happen in the next hundred years I would put at less than 0.01%.

That said,
scientists will likely be producing papers addressing these ideas for some
time. We’ll continue to cover them as they come out (and though things may look
painfully dismal for this technology, who knows what the future may hold).
In 2010,
NASA physicist Harold White revealed that he and a team were working on a
design for this faster-than-light ship, and this is the most recent design of
what such a ship might actually look like. As you can see in the image, the
ship rests between two enormous rings, which create the warp bubble.
Artist Mark
Rademaker worked on the project with White. In the release, Rademaker asserts
that he spent over 1,600 hours working on the design. The ship is called the
IXS Enterprise, and it is meant to fit the concept for a Faster Than Light
ship. Mike Okuda also brought input, and designed the Ship’s insignia.
To give you
some idea of just how awesome warp technology would be: A trip to the nearest
star (Proxima Centauri), which rests some four light-years from Earth, would
ordinarily take over 17,000 years. However, with the Alcubierre drive, it would
take a little under five months. For those of us who have a mental breakdown on
10 hour plane flights, 5 months might still seem like quite a bit of travel time.
But when we are talking about the vast cosmic distances between Earth and
Proxima Centauri, a 5 month trip would be an achievement of monumental
proportions (keep in mind, it took Curiosity 8 months just to reach Mars).
