NASA scientist and Advanced Propulsion Team Lead Harold White has the
kind of job thousands dream of and few achieve — he’s in charge of the
space agency’s efforts to determine if a faster-than-light warp drive is
actually possible and, if it is, how we might create one. Now, in
conjunction with artist Mark Rademaker, White has unveiled a new
starship model that illustrates how our consideration of the concept has
evolved over the decades.
Rademaker designed the first theoretical warp
ship concept to consciously echo the Matt Jeffries design for the
UEV-47; the first faster-than-light version of the Starship Enterprise.
This new version of the ship is chunkier, more compact, and according to
Harold White, a better match for what the mathematics of an Alcubierre
warp drive currently predict.Have we found any proof a warp drive can exist?
While a pretty concept design is nice, it still isn’t clear if a warp
drive can actually exist. NASA’s current experiments are an attempt to
measure whether the warp bubble Alcubierre theorized could exist can exist in our universe. There’s
an enormous gap between saying “Mathematically this doesn’t violate any
of the known laws of physics,” and saying “We’ve detected an actual
warp bubble in the real world.”
The inferometer experiment White oversees is designed to measure such
an effect at nanoscale. Currently, data is inconclusive — the team notes
that while a non-zero effect was observed, it’s possible that the
difference was caused by external sources. More data, in other words, is
necessary. Failure of the experiment wouldn’t automatically mean that
warp bubbles can’t exist — it’s possible that we’re attempting to detect
them in an ineffective way.
Nonetheless, the fact that we’re struggling to even discover if a warp
bubble can form is evidence of how much work remains until we could
plausibly tap the effect for space exploration. This new ship is as much
a PR move as a demonstration of capability — but the implications of a
warp bubble that allowed for even fractional light-speed travel are
enormous. The ability to move at 1% the speed of light would put the
entire Solar System within our reach; 0.1% light speed would make
exploration and colonization of Mars or the Moon a much simpler problem.
One good piece of news is that early fears that a hypothetical warp drive could be a star system-annihilating event have
been disproven by a better evaluation of the mathematics. New data
suggests this is unlikely to be an issue, though vessels observing the
warp drive ship in close proximity could still be at risk. Energy
requirements have also come down sharply, from Alcubierre’s initial
calculation that planetary-sized power sources would be required to more
recent data that suggests we could build a ship with a power source the
size of Voyager 2 — if we can create the necessary effect at the
appropriate scale. [Read: The hunt for alien, star-encompassing Dyson Spheres begins.]
For now, a warp drive remains science fiction — but if we can ever
build one, the impact on human civilization could rival the invention of
fire. Despite some bombastic reporting in other places, it’s not a
“real-life” Enterprise — not yet — but the fact that news of warp drive
research continues to grab headlines is an example of just how exciting
this technology could be.
