The idea of string theory was first floated in the 1960s and '70s. Scientists may have found the first observational evidence that supports string theory -- a hypothetical framework in physics ...

By considering spacetime as quantized, researchers propose a new approach to understanding gravity through quantum theory ... quantum mechanics and general relativity. As researchers delve deeper into ...

Researchers say they may have achieved Einstein's vision of a "unified field theory" that can unite two of nature's ...

The field was young ... in-a-generation paper showing that string theory could overcome the mathematical antagonism between general relativity and quantum mechanics, clearing a path that seemed ...

offering a new framework that unifies quantum mechanics and general relativity. The theory also introduces the G-field, a novel concept that could provide a quantum-based explanation for dark matter.

“I learned general relativity ... the field was partly an outgrowth of Einstein’s 1905 paper on photons. Einstein frequently and famously objected to the central tenet of quantum theory ...
