A team of researchers affiliated with multiple institutions in China, Germany and the US has found that data from the Event Horizon Telescope (EHT) rules out the likelihood of axion particles in a specific mass range around ...
Scientists at the University of Sussex have disproved the existence of a specific type of axion - an important candidate 'dark matter' particle - across a wide range of its possible masses.

Physicists have predicted the existence of dark matter, a material that does not absorb, emit or reflect light, for decades. While there is now significant evidence hinting to the existence of dark matter in the universe, ...
A new study, conducted to better understand the origin of the universe, has provided insight into some of the most enduring questions in fundamental physics: How can the Standard Model of particle physics be extended to explain ...
