PHOTONS that tick like a clock could allow atomic clocks to be synchronised with unheard-of accuracy. They could be used to help test Einstein’s theories of relativity, and lead to astonishingly ...

A photon emitted from a star a billion light-years away arrives at a telescope having experienced no time whatsoever. Not very little time. None. That result is not a loose approximation or a poetic ...

Gamma-ray burst GRB221009A has a silly but very apt nickname: BOAT, or the Brightest Of All Time. A supernova 2.4 billion light-years away exploded, shooting a jet of particles right at Earth. The ...

In 2022, astronomers detected an absurdly bright and long-lasting gamma ray burst, GRB 221009A —nicknamed “BOAT,” for ...

Scientists have built the first all-optical photonic time crystal, allowing them to reshape the behavior of terahertz light at extraordinary speeds. The breakthrough could open the door to ultrafast ...

The agreed laws of physics put limits on how far photons can travel in space – but researchers just identified a photon that's broken those fundamental rules and achieved the impossible, traveling 2 ...

Simulating the non-equilibrium dynamics of quantum field theories in nature is generally intractable with classical methods, but is a promising application for quantum computers. Unfortunately, ...
