Physicists at CERN’s Large Hadron Collider have uncovered new hints that certain particle decays may not behave as the ...

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 ...

Ultraheavy particle theory: New research indicates some ultrahigh-energy cosmic rays may be atomic nuclei heavier than iron, enabling them to travel vast cosmic distances. Historic particle events: ...

A straightforward math tweak could bring tachyon fields into line with the rest of physics. Tachyons are faster-than-light particles, and tachyon fields are special cases of quantum field. The math ...

According to our current understanding of the universe, equal amounts of matter and antimatter should have been produced in the Big Bang, then both annihilated. However, the universe is dominated by ...

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 ...

New cosmic ray theory: Researchers suggest ultraheavy atomic nuclei may explain the origins of the highest-energy cosmic rays ever detected. Why it matters: Ultraheavy nuclei could survive longer ...
