The gravitational wave signal, captured byLIGO in November 2025, has sparked a revolutionary hypothesis: the collision that produced the signal might not have involved conventional stellar black holes ...

Primordial magnetic fields may help explain why measurements of the universe’s expansion do not agree. Scientists have long known that the universe is expanding, yet there is still no agreement on how ...

On November 12, 2025, a ripple passed through the fabric of spacetime and triggered alarms at three gravitational-wave ...

Scientists have edged closer to discover the universe's long-held mystery surrounding the existence of primordial black holes ...

In November, a gravitational wave signal was captured by LIGO, and it made researchers very excited: a collision between two ...

It may well take years to prove, but a pair of University of Miami astrophysicists could be on the verge of a cosmic ...

All the black holes that astronomers have seen fall into one of three categories: stellar-mass black holes, intermediate-mass black holes, and supermassive black holes. Each is more massive than our ...
