Scientists pushed photons across the universe to test the speed of light—and found Einstein’s cosmic speed limit still holds ...
A team of engineers and scientists has shown for the first time that a hard-X-ray cavity can provide net X-ray gain, with ...

Light smashed its own speed limit by 100,000× to film atoms in action
Physicists are no longer content to let atoms blur into invisibility. By squeezing light into pulses that last just billionths of a billionth of a second and pairing them with cameras that tick at ...
Hamburg-based researchers have developed a system that generates better X-ray pulses at the European X-Ray Free-Electron ...
Artist’s impression of the powerful winds blowing from the bright X-ray source GX13+1. The X-rays are coming from a disc of hot matter, known as an accretion disc, that is gradually spiralling down to ...
Together with an international team, researchers from the Molecular Physics Department at the Fritz Haber Institute have ...
CERN's ALICE experiment has resolved the puzzle of deuteron formation, showing that most deuterons form via resonance-driven ...
Can we turn back time? Ask a savvy physicist, and the answer will be “it depends.” Schemes for retrograde time travel abound but usually involve irreconcilable paradoxes and rely on outlandish ...
