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 ...

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 ...

Ripples in space-time from a pair of merging black holes have been recorded in unprecedented detail, enabling physicists to test predictions of general relativity ...

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 ...

For hundreds of years, there was an immutable law of physics that was never challenged: that in any reaction occurring in the Universe, mass was conserved. That no matter what you put in, what reacted ...

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 ...
