A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Supersymmetry, a theory that posits every known elementary particle has a heavier “superpartner” particle, has been the superstar of theoretical physics for the past half century. Its ...

The key—according to the duo’s new research, which appears now in the peer reviewed journal Reports on Progress in Physics —lies in a particular type of theory called a gauge.

The theory also argues that time comes in three dimensions rather than just the single one we experience as continual forward progression. Space emerges as a secondary manifestation. "These three ...

Forty years ago this month, the physics community was electrified by a remarkable paper that hinted at the realization of Albert Einstein’s long-held dream: a unified theory of physical reality ...

Three scientists from the National Technical University in Athens, Greece published a paper in the journal Progress of Physics that details this slightly altered take on Einstein’s magnum opus ...
