What if the universe remembers? A bold new framework proposes that spacetime acts as a quantum memory. For over a hundred ...

The story begins with the black hole information paradox. According to relativity, anything that falls into a black hole is ...

Rogue black holes kicked from their galactic lairs are among the surprising predictions made by physicists using powerful computers to solve Einstein's equations of general relativity. David Appell ...

So far, the most accurate model describing gravity is still Einstein’s theory of general relativity. It states that gravity as we feel and observe it is a kind of side effect of the fabric of ...

Gravitational physics has become a truly experimental science as tests of the special and general theories of relativity reach new levels of precision Right on time When I was a first-term graduate ...

First of all, the prevailing quantum theory, quantum field theory, is fully relativistic from the onset. Relativity is “built into” the theory, so to speak. And it’s the only quantum theory that is ...

THIS monograph collects, in 87 pages, those deductions of the results of relativity theory that find most frequent application in physics. The applications of special relativity to kinematics, ...

Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve ...
