Hollywood films have championed the image of spacecrafts moving at unimaginable speeds, traveling seemingly faster than the speed of light. Whether referred to as “warp speed,” “super drive,” or “time travel,” movies from Star Wars to Star Trek to the satirical Space Balls, have all taken advantage of an apparently unrealistic form of transportation. But what if this incredibly efficient yet fictional type of travel was more practical than we ever imagined? What if “warp speed” was no longer in the realm of science fiction, but a mainstream, sensible mode of transportation?
Now before I go on, I feel obligated to inform you that the research, and necessary technology needed for such manipulation of space and time is in an extremely rudimentary form; that being said, recent breakthroughs in the logistics, calculations and theoretical plausibility of such transportation devices have reawakened the dreams of NASA scientists, and science-fiction geeks alike. Who doesn’t get excited by the idea of traveling through space?
Physicist, Miguel Alcubierre, first formulated this notion of traveling near the speed of light in his 1994 paper, “The Warp Drive: Hyper-Fast Travel within General Relativity,” suggesting a manipulation of the time and space surrounding the vessel, rather than actual acceleration. Such manipulation of the space in front and behind the “space ship,” would focus on an expansion and contraction of space and time. (Think of space and time as one entity –the physical mass and structure of the universe surrounding the vessel.) Expanding the space behind the ship would cause a forward motion similar to the expanding and contracting of a rubber band. If you were to stretch out a rubber band, releasing one end you would send the band flying through the air. Such forward movement is caused by the elasticity of the rubber band, pulling it expands the rubber, which sends it forward- just as expanding the space behind a ship would, hypothetically, send it in a forward direction. This constant expansion and contraction, in front of and behind the ship, could allow for travel near the speed of light (as nothing itself can exceed the speed of light, according to Einstein. However, space is able to contract at any speed, allowing for an equally impressive contraction.)
Now Alcubierre’s theory for travel at the speed of light hit a speed bump early in its life as it was determined that in order to manipulate time and space in such a drastic way, one would need massive amounts of energy- around the mass-energy of Jupiter or 317 planet Earths. The theory was deemed impractical and was since laid dormant. However, recently, physicist Harold White has put this notion of faster than light warp drive back on the science fiction map. White, after making adjustments to the design of the craft and re-crunching numbers, has reduced the necessary mass needed for travel from a Jupiter sized planet to a common space craft, some 1,600 pounds (or the weight of Back to the Future’s 1981 DeLorean)- now that already seems way more plausible.
And while a functional warp drive space shift is still in the distant future, such advancements are extremely exciting and promising. Imagine traveling 4.3 light years in a matter of weeks, in order to visit other solar systems!
