What exactly are quarks?

Quarks are the main components of protons. We have concluded through experimental probing of the proton with high energy electrons that inside the proton there are three massive objects, and based on Murray Gell-Mann’s theory, we call these quarks.

(There are other things inside the nucleus, such as gluons, but they are lighter in weight. The mass is dominated by the quarks.)

The biggest surprise about quarks is that we cannot extract them. If we put enough energy to pull one out, that energy is transformed into the creation of additional quarks, including an antiquark which binds with the one we extracted, to make (for example) a quark-antiquark pi meson. This feature is a consequence of the fact that the forces between quarks do not decrease with distance. Pi mesons consist of quark-anti-quark pairs.

This property is called “confinement” and it means that in the macroscopic world we will never see a free quark. Quarks can be semi-free in what we call a quark-gluon plasma. But that’s similar to saying that an electron is free when it conducts inside a metal. And unlike the electron, we can’t pull the quark off the surface of the plasma.

ninakamwene, You are correct. We are spirit beings living in the physical container which we call our body. At the very moment when we die, our spirit, which is alive, will leave our empty physical body and be ushered into the presence of God. Our spirit will live forever as it was intended to do Our spirit is actually who we are. Our body is just a temporary container.

I just want to know if it is something we can ever use to defeat the Borg!

The neutron also consists of quarks, as do other exotic hadrons. Quark antiquark pairs form mesons. The explanation is not very good, quarks are subject to quantum chromodynamics and there are six types, up, down, strange, charm, top, bottom

Thank you for this educational trivia in the category of: "What came first, the chicken or the egg?". I love science and yet I am aware of only One Consciousness. We are spiritual beings having a physical experience, among many others.This is a wonderful physical game. Are we having fun yet?

Very interesting. I assume that much we know about these things comes from the experiments using the Large Hadron Collider of CERN

Mass is relative, size matters not. An atom is massive. Quarks are what gives structure to all living elements so they don’t dissolve into nothingness!

With technology and science moving so fast, I believe it should read that at this point we cannot remove a quark!

"there are three massive objects inside protons"? How can there be massive objects inside a proton of an atom? Look up the definition of "massive".
