Physicists: Faster-Than-Light Travel Might Be Possible

Travel by bubble might seem more appropriate for witches in Oz, but two physicists suggest that a future spaceship could fold a space-time bubble around itself to travel faster than the speed of light.

To Bearly Go?: Baylor physicists propose way to travel faster than light

Baylor University physicists Gerald Cleaver and Richard Obousy have submitted a paper to ArXiv.org explaining how an engine could bend the rules of physics to travel faster than the speed of light without violating Einstein’s theory of relativity.

According to Discovery News, the proposal “involves expanding the fabric of space behind a ship into a bubble and shrinking space-time in front of the ship. The ship would rest in between the expanding and shrinking space-time, essentially surfing down the side of the bubble.

Warp Drive Engine Would Travel Faster Than Light

Tapping the Fabric of Space-Time

The tricky part is that the ship wouldn't actually move; space itself would move underneath the stationary spacecraft. A beam of light next to the ship would still zoom away, same as it always does, but a beam of light far from the ship would be left behind.

That means that the ship would arrive at its destination faster than a beam of light traveling the same distance, but without violating Einstein's relativity, which says that it would take an infinite amount of energy to accelerate an object with mass to the speed of light, since the ship itself isn't actually moving.

Dark Energy and Surfing Spacetime

robousy: The idea is as follows:

One essentially contracts space itself in front of a spacecraft, and expands space behind.

Because spacetime is not limited by the speed of light restriction, this provides a tantalizing mechanism to zip through space at faster than light speeds!

Beyond Four Dimensional Space-Time

According to some advanced physical theories more than our four dimensional space-time dimensions are needed for a complete description of the physical universe. The nearly-completed Large Hadron Collider (LHC) may be able to provide insight in the shape of these alternate dimensions.

High energy collisions by the nearly-completed Large Hadron Collider (LHC) may be able to generate particles that are sensitive to dimensions beyond our four dimensional space-time. These exotic particles, called Kaluza-Klein gravitons, would be highly sensitive to the geometry of extra-dimensions, giving scientists an idea about what lies beyond our universe. If these particles are detected, and if their characteristics can be measured, then perhaps the extra dimensions predicted by string theory may be proven to exist…

Particle Accelerator May Reveal Shape Of Alternate Dimensions

ScienceDaily (Feb. 4, 2008) — When the world's most powerful particle accelerator starts up later this year, exotic new particles may offer a glimpse of the existence and shapes of extra dimensions.

Adds Underwood, "If the cosmology and particle physics data agree, it's an indication we're on the right track."
