Frenemies with Physicality: Manufacturing Manifold Metrics
Sebastian Schuster
Physicality has the bad habit of sneaking up on unsuspecting physicists. Unfortunately, it comes in multitudinous incarnations, which will not always make sense in a given situatio…
ADM mass in warp drive spacetimes
Sebastian Schuster, Jessica Santiago, Matt Visser
What happens when a warp bubble has mass? This seemingly innocent question forces one to carefully formalize exactly what one means by a warp bubble, exactly what one means by havi…
Tractor beams, pressor beams, and stressor beams within the context of general relativity
Matt Visser, Jessica Santiago, Sebastian Schuster
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 careful…
Tractor beams, pressor beams, and stressor beams in general relativity
Jessica Santiago, Sebastian Schuster, Matt Visser
The metrics of general relativity generally fall into two categories: Those which are solutions of the Einstein equations for a given source energy-momentum tensor, and the "revers…
Generic warp drives violate the null energy condition
Jessica Santiago, Sebastian Schuster, Matt Visser
Three very recent articles have claimed that it is possible to, at least in theory, either set up positive energy warp drives satisfying the weak energy condition (WEC), or at the…
Sparsity of Hawking Radiation in Space-Time Dimensions Including Particle Masses
Sebastian Schuster
Hawking radiation from an evaporating black hole has often been compared to black body radiation. However, this comparison misses an important feature of Hawking radiation: Its low…
