When speaking of our universe, it's often said that "matter tells spacetime how to curve, and curved spacetime tells matter how to move." This is the essence of Albert Einstein's famous general theory ...

Lorentzian geometry forms the mathematical cornerstone of modern spacetime theory by providing a framework in which the causal structure and metric properties of the universe can be rigorously ...

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 ...

Physicists from the Eötvös Loránd University (ELTE) have been conducting research on the matter constituting the atomic nucleus, utilizing the world’s three most powerful particle accelerators. Their ...

Wormholes have long served as science fiction’s favorite shortcut through the cosmos, but a growing body of theoretical physics research suggests they will never function as tunnels. That does not ...
