Quantum field theory (QFT) remains the cornerstone of our understanding of particle interactions, unifying the principles of quantum mechanics with special relativity by describing particles as ...

String theory unifies all the forces of nature. Forces that seem very different, such as gravity and electricity, are deeply ...

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 ...

A recent experiment at Fermilab has delivered intriguing results that challenge standard predictions, adding fuel to the ...

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 ...

Brian Greene is one of the foremost scientists and science communicators of our time. Greene, a theoretical physicist at Columbia University, has been working for decades to advance our understanding ...

This article is the first part of a series about quantum field theory published by Quanta Magazine. Other stories in the series can be found here. Over the past century, quantum field theory has ...

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 ...
