|Dr. Richard Obousy describes an advanced space-propulsion concept based on modifying the local cosmological constant to facilitate an expansion/contraction of spacetime around a spacecraft to create an exotic form of field-propulsion. This idea is analogous to the Alcubierre bubble, but differs entirely in the approach, utilizing the physics of higher dimensional quantum field theory, instead of general relativity.
"...these warp drives, provide an unique and inspiring opportunity to ask the question 'what constraints do the laws of physics place on the abilities of an arbitrarily advanced civilization'. The main focus of the paper is to demonstrate that the manipulation of the radius of one (or more) of the extra dimensions found in quantum gravity theories, creates a local asymmetry in the cosmological constant which could be used to propel a space vehicle.
