The third Quantum Gravity conference took place at Penn State University from 21 to 25 July 2025, bringing together ...

Many theories are rock-solid: Scientists have just as much confidence in the theories of relativity, quantum mechanics, ...

What does it mean to be to space-time? The seemingly simple question gets to the essence of twentieth-century physics and has ...

Goodness, even in M-theory, which has eleven dimensions, time is still only one-dimensional. One can imagine how ...

With contributions by Dr. G. N. R. Tripathi NOTRE DAME, IN / ACCESS Newswire / August 23, 2025 / For the first time, researchers have presented a unified mathematical formulation that compactly brings ...

“How quantum mechanics and gravity fit together is one of the most important outstanding problems in physics,” Kathryn Zurek, a theoretical physicist at the California Institute of Technology (Caltech ...

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

String theory: The good, the bad, the energy-hungry For decades, physicists have sought a unified theory that can reconcile quantum mechanics, and by extension, the behavior of subatomic particles, ...

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not ...

ABSTRACT: We make more specific initial contributions of prior work w.r.t. Tokamaks, relic black holes, and a relationship between a massive graviton particle count and quantum number n, and also add ...

String theory's equations give rise to a near infinite variety of potential universes in a 'landscape.' This landscape is surrounded by a 'swampland' of solutions that are incompatible with any ...
