What holds quarks together in a proton?

The strong force binds quarks together in clusters to make more-familiar subatomic particles, such as protons and neutrons. It also holds together the atomic nucleus and underlies interactions between all particles containing quarks. The strong force originates in a property known as colour.

Are quarks inside protons?

Protons contain two up quarks and one down quark. Neutrons contain one up quark and two down quarks. It also holds together the quarks that make up the protons and neutrons. Note: In addition to electrons and quarks, physicists have identified a number of other subatomic particles.

What are quarks inside of?

A quark (/kwɔːrk, kwɑːrk/) is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei.

What particle binds quarks together?

Now, an international team of physicists has announced the strongest evidence yet for the existence of a long-sought particle that binds these quarks into protons, neutrons, and all the other bits of nuclear matter. It’s called the gluon.

What holds space together?

Gravity is the force that all objects with mass exert upon one another, pulling the objects closer together. The tiny particles that make up matter, such as atoms and subatomic particles, also exert forces on one another.

What force makes protons repel each other?

electromagnetic force
Inside the nucleus, the attractive strong nuclear force between protons outweighs the repulsive electromagnetic force and keeps the nucleus stable. Outside the nucleus, the electromagnetic force is stronger and protons repel each other.

Can quarks emit photons?

Yes, quark-antiquark annihilation can produce photons (though with lower probability than gluons) and quark-quark and quark-antiquark scattering can be mediated by photon exchange. Quarks are electrically charged which is enough to tell you they interact with photons.
