Neutrinos are the "ghost particles" in the Standard Model of Particle Physics. This is because they interact weakly with ordinary matter. An interesting property of neutrinos is that they can change their identities or "flavors" ...

In a new study, scientists report results from the PandaX-4T experiment, setting stringent limits on dark matter–nucleon interactions using low-energy data and the Migdal effect, ruling out significant parameter space for ...
Dark matter, composed of particles that do not reflect, emit or absorb light, is predicted to make up most of the matter in the universe. Its lack of interactions with light, however, prevents its direct detection using conventional ...
An international team of astronomers has carried out what is believed to be the largest ever cosmological computer simulation, tracking not only dark but also ordinary matter (such as planets, stars and galaxies), giving ...

Every day and night, hundreds of thousands of intense, brief flashes of radiation suddenly flicker on and then off all across the sky. These "fast radio bursts" are invisible to the naked eye, but to a radio telescope many ...
