Using a chain of atoms in single file to simulate the event horizon of a black hole, a team of physicists in 2022 observed the equivalent of what we call Hawking radiation – particles born from ...

What does the passage of time look like for a truly quantum object? The world’s best clocks may soon be able to answer this question, testing how time can stretch and shift in the quantum realm and ...

UC Riverside has developed a technology that enables scientists to peer deeper into the universe. Gravitational-wave science is on the verge of a major step forward, thanks to a new instrumentation ...

New observations of two black holes merging have confirmed predictions made decades ago by Albert Einstein, Stephen Hawking, and Roy Kerr. A decade ago, scientists first picked up ripples in the ...

Interference from human activity has always been a sticking point in astronomical observations. Radio astronomy is notoriously sensitive to unintentional interference—hence why there are "radio silent ...

Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter candidates. Unlike axions or WIMPs, these particles carry electric charge but ...
