Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not ...

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 ...

Dark matter could be made of particles that each weigh almost as much as a human cell and are nearly dense enough to become miniature black holes, new research suggests. While dark matter is thought ...

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 ...

A new theory says dark matter acts remarkably similar to subatomic particles known to science since the 1930s. A new theory says dark matter acts remarkably similar to subatomic particles known to ...

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.

For years, dark matter has been behaving badly. The term was first invoked nearly 80 years ago by the astronomer Fritz Zwicky, who realized that some unseen gravitational force was needed to stop ...

For the first time, researchers have performed a version of the famous double-slit experiment with antimatter particles. The double-slit experiment demonstrates one of the fundamental tenets of ...

Theoretical physicists have established a close connection between the two rapidly developing fields in theoretical physics, quantum information theory and non-invertible symmetries in particle and ...

Scientists working at the world’s largest atom smasher have caught a bizarre subatomic particle in the act of changing from matter to antimatter. The discovery could help us understand how the ...
