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 ...

In a groundbreaking study published in PRX Quantum, researchers led by Enrico Rinaldi have used quantum computing and AI to ...

Understanding singularities is key to resolving gaps in physics, with theories like string theory and causal set theory ...

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 ...

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 ...

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

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 ...

The image depicts an experiment in which heavy particles(illustrated as the moon), cause an interference pattern (a quantum effect), while also bendingspacetime. The ...
