Albert Einstein may not have been a surfer but he definitely knew a lot about waves; both the kind that can and can’t be surfed. For those of us who didn’t discover the Theory of General Relativity, ...

A new study has found that a hidden bias in galaxy models can skew gravitational-wave measurements of how fast the universe is expanding. That finding complicates one of astronomy’s most promising ...

For the first time, astronomers have spotted enormous, galaxy-scale shock waves rattling the "cosmic web" that connects nearly all known galaxies. These cosmic waves could reveal clues about how the ...

For the first time, astronomers have caught a glimpse of shock waves rippling along strands of the cosmic web — the enormous tangle of galaxies, gas and dark matter that fills the observable universe.

In November 2024, gravitational-wave detectors recorded the violent merger of two black holes billions ...

A soaring cosmic symphony surrounds us; its notes emerge from massive celestial objects crashing together hundreds of ...

Researchers from across the globe have revealed they have detected the largest collection of gravitational waves ever recorded. The gravitational waves, ripples in the very fabric of spacetime itself, ...
