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.

This figure depicts the particle trajectory inside the cyclone sampler during air sampling. The Washington University team used computational fluid dynamics (CFD) simulations to gain insight into the ...

Quantum mechanics replaced the clockwork certainty of classical physics with something far stranger: a framework in which particles do not follow single, predictable paths but instead exist as clouds ...
