They say they’ve discovered a new particle — dubbed X17 — that requires the existence of a fifth force of nature. The researchers weren’t looking for the new particle, though.

There may be a fifth force of nature, a new study suggests. "If true, it's revolutionary," study lead author Jonathan Feng, a professor of physics and astronomy at the University of California ...

The Search For The Fifth Force In 2023, on a sunny morning in the Utah desert, a spacecraft returned to Earth after one of the most epic journeys in the history of human exploration. It made a ...

Researchers meticulously tracked Bennu’s orbit using OSIRIS-REx spacecraft data, exploring whether unknown forces, such as a fifth force, could be affecting its path around the Sun. The study ...

Researchers may be on the brink of discovering evidence of a fifth fundamental ... controlled by fundamental forces. There are four known fundamental forces of nature—electromagnetism, the ...

We currently know of four: gravity, electromagnetism, the strong nuclear force (nuclear cohesion), and the weak nuclear force (radioactive decay). The discovery of a fifth could rewrite physics.

A tiny wobbling particle may be about to reveal a fifth force of nature, scientists behind one of the biggest particle physics experiments say. Physicists at the Fermi National Accelerator ...

They build on results announced in 2021 in which the Fermilab team first suggested the possibility of a fifth force of nature. Since then, the research team has gathered more data and reduced the ...

The Fermilab particle accelerator facility near Chicago is making remarkable progress in the quest to discover a potential new force of nature. Recent findings challenge the prevailing theory of ...

The standard model is beautiful – it elegantly lays out the foundational particles and three of the forces of nature (electromagnetism and the strong and weak nuclear forces that hold atoms ...
