Shock waves from tiny black holes in the early universe could explain how antimatter became so rare while matter is common.

In 2023, a subatomic particle smashed into the Mediterranean Sea with enough energy to rattle the foundations of physics. The particle was a neutrino, a fundamental subatomic particle that usually ...

A bizarre, record-breaking neutrino detected in 2023 may have originated from an exploding primordial black hole—a relic from the early universe. Scientists suggest these black holes could carry a ...

Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of ...

A neutrino slammed into Earth in 2023 with so much energy that it looked almost unreal. The particle carried about 220 peta–electron volts, or PeV, making it the most energetic neutrino ever reported.

The early universe is absolutely so far outside our understanding of how the world works it's hard to describe in words. Back then, the cosmos wasn't filled with stars and galaxies but with a boiling ...

The Universe’s biggest black holes may not be born giants after all. Scientists analyzing gravitational-wave signals from dozens of black hole collisions found evidence that the heaviest black holes ...

The most massive black holes in the universe detected by the ripples they make in spacetime were not born directly from ...

According to scientists, red supergiant stars should produce more supernovas. But astronomers just aren’t spotting them. Here ...
