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 ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

A team led by a physicist from City University of Hong Kong (CityU) recently developed a new quantum theory that explains the "light-induced phase" of matter and predicts its novel functionalities.

Einstein and the Quantum Revolutions Alain Aspect Univ. Chicago Press (2024) French physicist Alain Aspect is a pioneer in ‘quantum entanglement’ — connections between the quantum properties of ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

To put one of physicists’ most important theories to the test, scientists go to extremes. Extremely strong electromagnetic fields, that is. The theory of quantum electrodynamics, which describes ...

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...

Here’s what you’ll learn when you read this story: A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart ...
