Does Quantum Mechanics Reveal That Life Is But a Dream?

A radical quantum hypothesis casts doubt on objective reality

How Measuring Time Shaped History

From Neolithic constructions to atomic clocks, how humans measure time reveals what we value most

Can We Gauge Quantum Time of Flight?

Measuring the time it takes particles to travel between two points may be the best test yet for Bohmian mechanics

What Is Spacetime Really Made Of?

Spacetime may emerge from a more fundamental reality. Figuring out how could unlock the most urgent goal in physics—a quantum theory of gravity

ArXiv.org Reaches a Milestone and a Reckoning

Runaway success and underfunding have led to growing pains for the preprint server

Reprogrammable Eutelsat Quantum Satellite Shifts Missions on the Fly

A new type of satellite opens mobile possibilities

On the Heels of a Light Beam

In a First, Physicists Glimpse a Quantum Ghost

After a decade of work, researchers have achieved the first ever experimental reconstruction of a quantum wave function

Unexplained Results Intrigue Physicists at World’s Largest Particle Collider

Muons and electrons might not experience the same fundamental interactions, contrary to Standard Model predictions

AI Designs Quantum Physics Experiments beyond What Any Human Has Conceived

Originally built to speed up calculations, a machine-learning system is now making shocking progress at the frontiers of experimental quantum physics

Why the Physics Nobel Honored Climate Science and Complex Systems

The prestigious award finally recognizes work that helped scientists understand climate change and, more broadly, find order in disorder

Is There a Thing, or a Relationship between Things, at the Bottom of Things?

Quantum mechanics inspires us to speculate that interactions between entities, not entities in themselves, are fundamental to reality

Talking to My Daughter Can Be Harder Than Learning Quantum Mechanics

Ordinary human dilemmas are tougher to solve than the most difficult problems of physics and mathematics

What God, Quantum Mechanics and Consciousness Have in Common

Theories that try to explain these big metaphysical mysteries fall short, making agnosticism the only sensible stance

Black Holes, Quantum Entanglement and the No-Go Theorem

New research shows that there are problems even quantum computers might never be able to solve

Death by Primordial Black Hole

If such an object a mere 1,000 times bigger than an atom passed through your body, the result would not be pretty

Scientists Supersize Quantum Effects with Entangled Drum Duet

Two teams have demonstrated new degrees of quantum measurements in micron-sized metal drums

Is the Standard Model of Physics Now Broken?

The discrepancy between the theoretical prediction and the experimentally determined value of the muon’s magnetic moment has become slightly stronger with a new result from Fermilab...

Long-Awaited Muon Measurement Boosts Evidence for New Physics

Initial data from the Muon g-2 experiment have excited particle physicists searching for undiscovered subatomic particles and forces

The Cosmological Constant Is Physics’ Most Embarrassing Problem

Physicists have new ideas about why the energy of empty space is so much weaker than it is predicted to be
