Tractor beams, pressor beams, and stressor beams within the context of general relativity

Understand

Both traversable wormholes and warp drives, concepts originally developed within the context of science fiction, have now (for some 30 odd years) been studied, debated, and carefully analyzed within the framework of general relativity.

• An overarching theme of the general relativistic analysis is unavoidable violations of the classical point-wise energy conditions.
• Another science fiction trope, now over 80 years old, is the tractor beam and/or pressor beam.
• We shall discuss how to formulate both tractor beams and/or pressor beams, and a variant to be called a stressor beam, within the context of reverse engineering the spacetime metric.
