In 2018, researchers created the world’s fastest-spinning object that reached 60 billion rpm – now that seems like the teacup ride at Disneyland. The same team has broken its own record, creating a new nano-scale rotor that spins five times faster.

The hunt for dark matter – the mysterious stuff that seems to outnumber regular matter by a ratio of five to one – has so far turned up no direct trace. Now, researchers at CERN have tried a new approach, using another strange substance – antimatter.

The detection of the Higgs boson at CERN in 2012 is one of the biggest scientific discoveries of the decade. Now the ATLAS and CMS Collaborations have made the most precise measurement of its mass to date.

Rather than trying to see dark matter, a new experimental design from Stockholm University listens for it instead, using an “axion radio.”

The 2019 Nobel Prize in Physics recognizes three scientists for improving our understanding of the universe's history and Earth's place in the cosmos.

The Kamioka Gravitational-wave Detector (KAGRA) in Japan will join LIGO in the US and Virgo in Italy to triangulate where any waves are coming from.

A new experiment shows that even massive molecules containing up to 2,000 atoms can exist in two places simultaneously.

In a new distance record, researchers have sent a photon, entangled with an ion, down a 50-km (31-mi) long optical fiber.

Scientists from Austria and China throw Schrodinger's Cat for a loop.

Although it outnumbers regular matter by a ratio of five to one, dark matter is frustratingly elusive, and efforts to hunt down different types of candidate particles have revealed no direct trace. Now, researchers from Max Planck have proposed a new hypothetical particle that might be behind dark matter – the superheavy gravitino – and outlined just how we might find them.

The universe is believed to be expanding at an accelerating rate, thanks to a mysterious force dubbed dark energy. But how exactly does this force work?

Few things are as mysterious as dark matter. Now, a physicist from Johns Hopkins University has outlined a new theory that helps to explain the stuff but at the same time makes it seem even more bizarre. According to the study, dark matter may have originated before the Big Bang.
