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 ...

Here’s what you’ll learn when you read this story… A mind-bending theory called quantum immortality suggests that your ...

Columnist Natalie Wolchover examines the latest developments in the “forever war” over whether string theory can describe the ...

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 ...

The geometry or shape of a quantum system is mathematically expressed by a tool called the quantum geometric tensor (QGT). It also explains how a quantum system's state changes when we tweak certain ...

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...

The nature of gravity — and whether it can be reconciled with quantum mechanics — is one of the biggest mysteries in physics. Most researchers think that at a fundamental level, all phenomena follow ...

MIT mathematicians tracked a droplet as it bounced through a structure inspired by the theoretical “quantum bomb test.” The shows the droplet’s trajectories when the "bomb" is present, and the right ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

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 ...
