Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in ...

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 ...

Non-relativistic string theory offers an innovative perspective on the formulation of quantum gravity, providing a tractable limit of fully relativistic string theories by expanding in inverse powers ...

WEST LAFAYETTE, Ind. — A team of Purdue University researchers has been awarded a $1 million W.M. Keck Foundation grant to experimentally test an early prediction originated from string theory: An ...

A new theory suggests that the unification between quantum physics and general relativity has eluded scientists for 100 years because huge "fluctuations" in space and time mean that gravity won't play ...

For decades, physicists have struggled to reconcile the laws governing the very small with those that describe the vast ...

Quantum researchers in the twenty-first century are part of an international network that requires a great deal of ...
