By using a rare thorium nucleus as a timekeeper, physicists have demonstrated the first working nuclear clock, a device that could lead to even more precise clocks and new ways to search for dark ...

The universe is governed by four fundamental forces: gravity, electromagnetism and the strong and weak nuclear forces. These forces drive the motion and behavior of everything we see around us. At ...

Research from a team of physicists at the University of New Hampshire is advancing the understanding of how protons, which comprise 95% of the mass of the visible universe, interact with each other.

We all know about the four fundamental forces of nature: gravity, electromagnetism, and the weak and strong forces between atoms. But could there be a fifth force still waiting to be discovered? A new ...

In new work, high-energy physicists have observed two long-sought quantum states in the bottomonium family of sub-atomic particles. The result will help researchers better understand one of the four ...

There's a beautiful, elegant idea that's out there in physics: that everything we see, perceive, and interact with in this Universe is just a different manifestation of the same fundamental force in ...

(via PBS Space Time) Our universe seems pretty complicated. We have a weird zoo of elementary particles, which interact through very different fundamental forces. But some extremely subtle clues in ...
