Diagrammatic representation of the entropic quantum gravity action. The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the ...

Everything around us, from atoms and molecules to planets and galaxies, is governed by two extraordinarily successful theories of physics: quantum mechanics and gravity. Quantum mechanics explains the ...

CHAPTERS: 0:00 - Deterministic to probabilistic universe 1:55 - Why must we quantize gravity? 6:22 - What is the central conflict with gravity and quantum mechanics? 9:09 - Why is quantizing gravity ...

Scientists have redefined gravity to explain the Big Bang and perhaps change our picture of the earliest moments of the cosmos. This new framework of "quantum gravity" may explain aspects of the Big ...

In a new Physical Review Letters study, researchers propose an experimental approach that could finally determine whether gravity is fundamentally classical or quantum in nature. The nature of gravity ...

Relationism is the idea that objects, entities and reality itself is defined and created by interactions and relationships. I will argue that relations aid in the understanding of spacetime for a ...

Physicists have tested the hypothesis that gravitational fluctuations in space-time can destroy quantum superposition and explain why large objects do not behave like particles. An experiment in the ...

The odds of the bet Jonathan Oppenheim made in 2023 are generous, even at 5000 to 1. But if he wins, it could transform our view of the universe. The physicist is wagering that space-time, and ...

Jonathan Oppenheim says scientists may be looking for answers to the biggest mystery in physics in the wrong place. According ...
