The prevailing assumption has been that Einstein's theory of gravity must be modified, or 'quantized', in order to fit within quantum theory. This is the approach of two leading candidates for a ...

Heterotic string theory remains a captivating framework in the pursuit of unifying quantum mechanics with gravity. By merging aspects of bosonic and supersymmetric strings, it provides a fertile ...

VATICAN CITY (RNS) — Renowned physicists, including two Nobel Prize winners, will gather at the Vatican Observatory near Rome next week to ponder the unresolved mysteries of the cosmos and to honor ...

Scientists have achieved two major breakthroughs: experimentally uncovering how quantum order collapses in real-world environments and proposing new gravity models that could replace the Big Bang ...

A radical theory that consistently unifies gravity and quantum mechanics while preserving Einstein's classical concept of spacetime has been announced in two papers published simultaneously by UCL ...
