In scifi, FTL is achieved by jumping around spacetime, because accelerating to light speed would require infinite energy (as per Einstein’s Theory of Relativity. Gamma is not your friend). However, now some physicists have theorized a way to accelerate to c and beyond, by “surfing” on a wave of space-time:
In theory, the universe grew faster than the speed of light for a very short time after the Big Bang, driven by the dark energy that represents about 74 percent of the total mass-energy budget in the universe. Dark matter constitutes 22 percent of the budget, and normal matter (stars, planets and everything you see) makes up the remaining 4 percent or so.
Strange as it sounds, current evidence supports the notion that the fabric of space-time can expand faster than the speed of light, because the reality in which light travels is itself expanding.
Cleaver and Richard Obousy, a Baylor graduate student, tapped the latest idea in string theory to devise how to manipulate dark energy and accelerate a spaceship. Their notion is based on the Alcubierre drive, which proposes expanding space-time behind the spaceship while also shrinking space-time in front.
Cleaver told Space.com, “The dark energy is simultaneously decreased just in front of the ship to decrease (and bring to a stop) the expansion rate of the universe in front of the ship. If the dark energy can be made negative directly in front of the ship, then space in front of the ship would locally contract.”
All you need to do is manipulate the 11th dimension. And it doesn’t even require infinite energy. Just a Jupiter mass or so. Simple!
