Particle never before seen on Earth detected; it could come from a primordial black hole and the origin of the universe.

A cluster of recent theoretical papers has laid out mathematical frameworks for propelling spacecraft at speeds ranging from ...

Another theory held that the forces between two particles falls off exponentially in direct relationship to the distance between two particles and that the factor by which it drops is not dependent on ...

Detected in 2021, the Amaterasu particle ranks among the most energetic cosmic rays ever observed, carrying an estimated 244 ...

The tiny fatty capsules that deliver COVID-19 mRNA vaccines into billions of arms may work better when they're a little ...

It was a bold thought experiment: that only one electron makes up the entire universe. The most famous conversation about it took place between Richard Feynman, PhD, and John Wheeler, PhD, both ...

New analysis by Francesca Capel and Nadine Bourriche narrows possible sources of the Amaterasu cosmic ray, suggesting nearby galaxies like M82 rather than the Local Void.

It's the second most energetic cosmic ray ever to be detected striking Earth.

In some quantum materials, which are materials governed by quantum mechanical effects, interactions between charged particles (i.e., electrons) can prompt the creation of quasiparticles called anyons, ...

Scientists say an ultra-powerful neutrino once thought impossible may be explained by an exotic black hole model involving a so-called “dark charge.” ...

For a mere moment after the Big Bang, no neutrons or protons are thought to have existed. These neutral and positively charged particles, respectively, make up the center of all atoms today. But ...

After years of confusion, a new study confirms the proton is tinier than once thought. That enables a test of the standard model of particle physics.
