A supercharged neutrino that smashed into our planet in 2023 may have been spit out by an exploding primordial black hole ...

A neutrino with almost unimaginable energy slammed into Earth in early 2023, carrying roughly 220 petaelectronvolts, far beyond anything human machines can produce. The event, tagged KM3-230213A, has ...

It’s unclear whether science as a discipline—and scientists as people—will ever be able to answer some questions definitively ...

For the past few years, a series of controversies have rocked the well-established field of cosmology. In a nutshell, the predictions of the standard model of the universe appear to be at odds with ...

Astroparticle physics and particle cosmology represent converging disciplines that strive to understand the universe from its largest structures down to its most fundamental constituents. In this ...

The audit concludes that the Selection-Stitch Model offers something modern physics has lacked for decades: Simplicity. It replaces dozens of arbitrary parameters with a single, rigid geometry. It ...

Dark matter remains one of the most compelling enigmas in modern cosmology. Although it does not emit light, its gravitational influence is essential for the formation and evolution of cosmic ...

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new ...
