A quark is a fundamental building block of the universe. ... Evidence has been gathered over the years that shows the larger an atom's nucleus, the slower the quarks inside move.

Study of quark speeds finds a solution for a 35-year physics mystery ... The larger an atom's nucleus, the more SRC pairs there were, and the slower the quarks that were measured.

Scientists have been studying the nucleus of the atom ever since Ernest Rutherford first discovered it in 1909. Twenty-five years later, scientists were already describing the nucleus as a ...

Dragging one up quark and two down quarks to the Assembly area forms a neutron. From the Assembly area, a neutron or proton is dragged to the atom's nucleus at the center of the atom building area.

Absolutely bonkers experiment measures antiproton orbiting helium ion It's a potentially useful technique—and it's surprising that it works.

Even the most powerful telescopes have not yet been able to see far enough back in time to witness events from the Big Bang.

It shows that the ephemeral dance of proton-neutron pairs etches an indelible signature on the quark-gluon landscape one that is now apparent in theory as well as experiment. The atomic nucleus, ...

"Considering that the quark-gluon plasma we create in gold-gold collisions at RHIC fills a space that is approximately the size of the nucleus of a single gold atom, the possible hot spots we're ...

A proton is one of the subatomic particles that make up the nucleus of an atom. As small as protons are, they are composed of even tinier elementary particles known as quarks, which come in a ...

First, let's explore the atom's architecture. Formed from a cluster of protons and neutrons at the center of an atom, a nucleus is 10,000 times smaller than the atom as a whole, "like a fly in a ...
