An enigmatic connection between the forces of nature is allowing physicists to explore gravity’s quantum side.

An unexpected superconductor was beginning to look like a fluke, but a new theory and a second discovery have revealed that emergent quasiparticles may be behind the effect.

A new thought experiment indicates that quantum mechanics doesn’t work without strange numbers that turn negative when squared.

Since they can’t prod actual universes as they inflate and bump into each other in the hypothetical multiverse, physicists are studying digital and physical analogs of the process.

For decades, astronomers debated whether a particular smudge was close-by and small, or distant and huge. A new X-ray map supports the massive option.

Over the past two years, astronomers have rewritten the story of our galaxy.

Physicists plan to leave no stone unturned, checking whether dark matter tickles different types of detectors, nudges starlight, warms planetary cores or even lodges in rocks.

In 2020, researchers reported that they had created a room-temperature superconductor. That paper has now been retracted.

Renormalization has become perhaps the single most important advance in theoretical physics in 50 years.
