A cluster of recent theoretical papers has laid out mathematical frameworks for propelling spacecraft at speeds ranging from ...

In the warp-drive literature, a shortage of imagination has never been the most recalcitrant hindrance. It has been one, savage demand: the demand of negative energy “exotic.” Recent theoretical ...

Casimir cavities are mysterious spaces between microscopic metal plates in a vacuum. Areas of diminished energy between the plates cause them to push toward each other, as if trying to fill the ...
