Submission + - Hyperdrive Propulsion Could Be Tested At The LHC (

KentuckyFC writes: In 1924, the influential German mathematician, David Hilbert, calculated that a stationary mass should repel a particle moving towards or away from it at more than half the speed of light (as seen by a distant inertial observer). Now an American physicist has pointed out that the equal and opposite effect should also hold true: that a relativistic particle should repel a stationary mass. This, he says, could form the basis of a "hyperveolcity propulsion drive" for accelerating spacecraft to a good fraction of the speed of light. The idea is that the repulsion allows the relatavisitic particle to deliver a specific impulse that is greater than its specific momentum, an effect that is analogous to the elastic collision of a heavy mass with a much lighter, stationary mass, from which the lighter mass rebounds with about twice the speed of the heavy mass. Unlike other exotic hyperdrive proposals, this one can be tested using the world's largest particle accelerator, the LHC, which will generate beams of particles with the required energy (abstract). Placing a test mass next to the beam line and measuring the forces on it as the particles pass by, should confirm the theory--or scupper it entirely.
