Warp-speed Spaceflights? Make It So

A new method to cause a spaceship to effectively travel faster than the speed of light, without breaking the laws of physics, has been theorized by physicists. The researchers suggest that, by manipulating the extra spatial dimensions of string theory around a spaceship with an extremely large amount of energy, it would create a “bubble” that could cause the ship to travel faster than the speed of light.
Dr. Gerald Cleaver, associate professor of physics at Baylor University, and Richard Obousy, a Baylor graduate student, believe manipulating the tenth spatial dimension would alter the dark energy in three large spatial dimensions — height, width and length — to create this bubble. Cleaver said positive dark energy is currently responsible for speeding up the expansion rate of our universe as time moves on, just like it did after the Big Bang, when the universe expanded much faster than the speed of light for a very brief time.
“Think of it like a surfer riding a wave,” said Cleaver, who co-authored the paper with Obousy about the new method. “The ship would be pushed by the spatial bubble and the bubble would be traveling faster than the speed of light.”
The method is based on the Alcubierre drive, which proposes expanding the fabric of space behind a ship and shrinking space-time in front of the ship. The ship would not actually move, rather the ship would sit in a bubble between the expanding and shrinking space-time dimensions. Since space would move around the ship, the theory does not violate Einstein’s Theory of Relativity, which states that it would take an infinite amount of energy to accelerate a massive object to the speed of light.
String theory suggests the universe is made up of multiple dimensions. Height, width and length are three dimensions, and time is the fourth dimension. String theorists used to believe that there were a total of 10 dimensions, with six other dimensions that we can not yet identify because of their incredibly small size. A new theory, called M-theory, takes string theory one step farther and states that the “strings” of which all things are made actually vibrate in an additional spatial dimensional, which is called the tenth dimension. It is by changing the size of this tenth spatial dimension that the researchers believe the strength of the dark energy could be altered in such a manner to propel a ship faster than the speed of light.
The physicists estimate that the amount of energy needed to influence the extra dimension is equivalent to the entire mass of Jupiter being converted into pure energy for a ship measuring roughly 10 meters by 10 meters by 10 meters. “That is an enormous amount of energy,” Cleaver said. “We are still a very long ways off before we could create something to harness that type of energy.”
