Einstein rejected it, calling it “spooky action at a distance,” but decades of experiments proved him wrong. From satellite tests to lab-created photon pairs, entanglement continues to defy common ...

This experiment uses a warm liquid on ice to explore how heat actually moves and dissipates. Instead of melting evenly, the ice reacts in unexpected patterns that reveal strange thermal behavior. It’s ...

From a particle smasher encircling the moon to an “impossible” laser, five scientists reveal the experiments they would run ...

The most beautiful experiment in physics, according to a poll of Physics World readers, is the interference of single electrons in a Young’s double slit. Robert P Crease reports Simply beautiful – the ...

No one can question the impact of science on human civilization, and the importance of experimentation in science is equally undeniable. Some experiments confirm what we already know, others suggest a ...

Two papers challenged the existence of theorized particles called sterile neutrinos that might account for mysteries like the ...

Three thought experiments involving “demons” have haunted physics for centuries. What should we make of them today?

A virtual laboratory under development at the University of North Carolina at Greensboro aims to let students experiment with physics concepts without physically being in a lab. Computer simulations ...

The original version of this story appeared in Quanta Magazine. There are precision measurements, and then there’s the Laser Interferometer Gravitational-Wave Observatory. In each of LIGO’s twin ...
