A new solution to Albert Einstein's theory of general relativity suggests hypothetical gravitational stars that look like black holes could be nested within one another. When you purchase through ...

A newly developed solution to the equations at the heart of Albert Einstein's most revolutionary theory suggests hypothetical stars called "nestars" could be made from stacked gravitational stars, or ...

Using software that incorporates all of the field theory equations developed by Einstein as part of his general theory of relativity, research teams from Europe and the United States have started ...

The evolution of quantum mechanics has continuously deepened our understanding of the microcosm, guiding researchers from the seminal formulation of the Schrödinger equation to more refined ...

Earlier this year, researchers discovered that photon-emitting atoms moving through a vacuum experienced a friction-like force never detected before. This was not just unexpected but it also ...

Michio Kaku explores the eureka moment when Einstein came up with special relativity, the theory that spawned E = mc2. ByMichio Kaku Tuesday, October 11, 2005 NOVA Einstein realized that the world ...

In cosmology, questions about conditions before the Big Bang are often dismissed as unscientific or unanswerable. However, a recent paper in Living Reviews in Relativity by Eugene Lim from King’s ...
