For decades, physicists searched for a missing piece of nature's puzzle, an elusive particle believed to explain why matter ...

In a first, CERN physicists succeeded in observing matter-antimatter imbalance in baryons, fundamental particles that make up most of the observable universe. Reading time 3 minutes All matter in our ...

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible substance thought to give the universe its shape and structure. They say the ...

NASA's Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of galaxies, one of the densest known galaxy collections in the universe — and where the effect of dark ...

In recent years, a curious hypothetical particle called the axion, invented to address challenging problems with the strong nuclear force, has emerged as a leading candidate to explain dark matter.

Because we haven't found anything yet, we've started to wonder if dark matter might be lighter or heavier than we thought. When you purchase through links on our site, we may earn an affiliate ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

The hypothetical faster-than-light particle known as the tachyon may marry with the special theory of relativity, according to a team of physicists, making its existence more plausible. Tachyons are a ...

To validate this hypothesis, the researchers cross-verified the results using another model, further confirming the correlation between anomalous particle yields and quark-matter formation.
