For decades, physicists have chased the dream of unifying all of nature’s forces under a single theory. String theory has long been a top candidate, offering a single mathematical framework that could ...

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 ...

UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

"When my student showed me the data I thought she must be wrong," Boston College professor and lead researcher Kenneth Burch told Live Science. "It's not every day you find a new particle sitting on ...
