Physical Review D (PRD), a leading journal in elementary particle physics, field theory, gravitation, and cosmology, appears monthly in two sections, D1 and D15: D1 covers experimental and theoretical particle physics as well as phenomenological aspects of quantum field theory. D15 covers gravitation, cosmology, astroparticle physics, formal aspects of the theory of particles and fields, and related areas.
A team of physicists at the University of Edinburgh's School of Physics and Astronomy has used mathematical calculations to show that quantum communications across interstellar space should be possible. In their paper published ...
Scientists behind a theory that the speed of light is variable - and not constant as Einstein suggested - have made a prediction that could be tested.

A team of theoretical physicists have discovered a strange structure in space-time that to an outside observer would look exactly like a black hole, but upon closer inspection would be anything but: they would be defects ...

Last year CERN announced the finding of a new elementary particle, the Higgs particle. But maybe it wasn't the Higgs particle, maybe it just looks like it. And maybe it is not alone.

A new study, led by researchers at the University of Cambridge and reported in the journal Physical Review D, suggests that some unexplained results from the XENON1T experiment in Italy may have been caused by dark energy, ...

According to Einstein's theory of relativity, the curvature of spacetime was infinite at the big bang. In fact, at this point all mathematical tools fail, and the theory breaks down. However, there remained the notion that ...

For several years, astronomers and cosmologists have theorized about the existence of an additional planet with a mass 10 times greater than that of Earth, situated in the outermost regions of the solar system. This hypothetical ...
The scientific collaborations LIGO and Virgo have detected gravitational waves from the fusion of two black holes, inaugurating a new era in the study of the cosmos. But what if those ripples of space-time were not produced ...

A group of researchers at Sofia University has found evidence that suggests the reason that a wormhole has never been observed is that they appear almost identical to black holes.
