New research conducted by nuclear physicists is using a method that connects theories of gravitation to interactions among the smallest particles of matter. The result is insight into the strong force ...

Protons sit in the nuclei of all atoms, but they are not fundamental particles: They are made of three quarks held together by the strong nuclear force. The strength of this interaction is actually ...

The strong force binds quarks together inside protons, neutrons, and other particles. Unlike gravity or electromagnetism, the strong force becomes stronger as particles move farther apart, similar to ...

We are getting closer to understanding when the strong nuclear force loosens its grip on the most basic constituents of matter, letting quarks and gluons inside particles abruptly turn into a hot ...

Atomic nuclei exhibit multiple energy scales simultaneously—ranging from hundreds down to fractions of a megaelectronvolt. A new study demonstrates that these drastically different scales can be ...

Despite dozens of experiments over the years, scientists still don't have a precise measurement for gravity's strength. Why is that?

Physicists are facing a paradoxical situation. On one hand, they are searching for a fifth fundamental force that could ...

The power of gravity is writ large across our visible universe. It can be seen in the lock step of moons as they circle planets; in wandering comets pulled off-course by massive stars; and in the ...
