It is well known that gravity does distort space. However, his original paper claimed that it would take a lot of matter, and an awful lot of energy (the amount of energy locked into that matter according to E=mc2) to distort spacetime significantly. This is the real reason for Miguel Alcubierre's pessimistic calculations of how much negative energy a warp drive would require. There is hope though. If another force can be directly converted into gravity, that would avoid those extreme energy requirements. String theory predict that gravity and electromagnetism unify in hidden dimensions.

  • It is well known that gravity does distort space. However, his original paper claimed that it would take a lot of matter, and an awful lot of energy (the amount of energy locked into that matter according to E=mc2) to distort spacetime significantly. This is the real reason for Miguel Alcubierre's pessimistic calculations of how much negative energy a warp drive would require. There is hope though. If another force can be directly converted into gravity, that would avoid those extreme energy requirements. String theory predict that gravity and electromagnetism unify in hidden dimensions. Alcubierre predicted that warp drive would require negative energy. Small amounts of negative energy has been extracted from the vacuum energy using parallel plates extremely close to each other (the Casimir effect). It has been suggested that it would be possible to use the effect practically using thousands of plates. I have a new idea about how to make the effect stronger still. Fit more plate surface into the same volume by curving the plates (curve them all in the same way to keep them parallel).
