Protons and neutrons are themselves made up of particles known as quarks and gluons. But matter can have an opposite in the form of antimatter. In fact, all the subatomic particles in matter either have their own anti-twins (antiquarks, antiprotons, antineutrons, and antileptons such as anti...
Fundamentally, matter is composed of elementary particles calledquarksandleptons, both of which are considered elementary particles in that they aren't made up of smaller units of matter. Quarks -- groups ofsubatomic particlesthat interact by means of astrong force-- combine into protons and neutr...
A particle composed of three quarks is classified as a: photon meson particon pion baryon Which quarks will you find in a neutron? only one answer is correct A: Three up quarks. B: Two up quarks and a down quark. C: Two down quarks and an up quark. D: One charm quark, one up ...
What is neutron emission? Why is energy released in the proton proton chain? Who discovered protons? What are vector-like quarks? What is light's elementary particle? What is quark-gluon plasma? What is a beta particle emitted from?
The theory that describes the strong nuclear force known as Quantum-Chromodynamics is notoriously difficult to solve. However, it can be simulated on supercomputers built and maintained at DOE facilities. DOE has been a leader in the study of quarks and gluons since the 1960s. The idea of quar...

Neutrons are uncharged particles found within all atomic nuclei (except for hydrogen). A neutron's mass is slightly larger than that of a proton. Like protons, neutrons are also made of quarks — one "up" quark (with a positive 2/3 charge) and two "down" quarks (each with a negative...
The only “reason” is that if it were even a little different, life as we know it would be impossible. The masses of the proton and neutron almost coincide. Why? If the masses of either were even a little different, life as we know it would be impossible. The energy of empty space...
Yet general relativity's string of experimental successes gloss over what many physicists see as a fatal theoretical failure: It describes a classical spacetime, but the universe ultimately appears to be quantum or made up of particles (or "quanta") such asquarksand electrons. ...
One way to think about the Standard Model is as a family tree for particles. For example, the Standard Model tells us how the atoms that make up our bodies are made ofprotonsand neutrons, which in turn are made of elementary particles calledquarks. ...
