quark.noun,.plural.quarks
smaller than an atom, they are made up of even smaller matter called tachyons and so on down the chain. As you can see in the graphic there are 6 types of quarks. We see no end to it and postulate that beyond what we can see with powerful microscopes, it continues into infinity; quarks residing within atoms make the protons and neutrons of the atom; physicists now know that all matter is comprised of electrons, up quarks and down quarks. A quark is produced when a cosmic ray.collides with the nucleus of an atom, immediately decaying into other particles. 

A quark is any class of.unobserved.subatomic particles (much tinier than the atom, as groups of them reside therein) with a fractional electrical charge, of which proton, neutrons and other hadrons are thought to be composed.

Quarks come in six varieties – up, down, strange, charm, bottom and top. Each of these six quarks have an antiparticle bringing the total to twelve.

Quarks are the particles that trigger radiation in the neutron. 

A quark has a fractional electric charge of magnitude (greatness of rank or position) one third or two thirds that of the electron and is regarded as constituents of all hadrons.

A quark pairs with one of its opposites, an antiquark, to create a type of matter called a meson. In the second method, three quarks gather to form baryons, such as protons and neutrons. 

"Apparently there are a lot more ways of putting things together than we thought".said Syracuse University physicist Sheldon Stone, who runs experiments based on data from the Large Hadron Collider in Europe.

Quarks combine in groups of 3 to produce baryons, a subclass of hadrons. Quarks have ½ integral spins. The up has +2/3, the down and strange -1/3.

A proton consists of 2/3+2/3-1/3=1. A neutron has -1/3-1/3+2/3=0

Quarks have other antisymmetric electrical attributes deemed 'color' (red, green, blue). These 'colors' combine to produce a colorless mix.

Quarks reside in individual nucleons and yet unlike an atom or the nucleons in atoms, an incredible 20 tons of force within a maximum span of a trillionth of a meter between each quark ensures they cannot be taken apart.

This peculiar property is unknown in all other scales of matter and is amazing for two reasons: the small scale and quarks, though made up of parts, can not be taken apart like the parts in other wholes, such as a flower, frog or fridge. 

Scientists have crushed them, turning them into gas, etc., but they remain constant in integrity. Quarks are held in this tight bond with each other by an exchange of gluons, creating an unbelievable secure binding of electrical pathways between them. The action of this remarkable exchange and the many possibilities resulting from it, when characterized in mathematical models, is termed quantum.chromodynamics

quantum string.noun,.plural.quantum strings
also known as superstrings, are strings of matter, that are now proven to be the main building blocks of all that is, having an incredibly short length, that of 1,000,000,000,000,000,000,000,000,000,000,000 of them end to end taking up only one centimeter (about the width of your finger). They are 100 billion times smaller than a proton and theoretical physicists postulate that these strings possess enormous gravitational force due to their dense mass apparently causing gravitional lensing (photon.trajectories are bent).

These strings account for the elementary particles. They 'replace' space. They are space. They comprise all we see and know of. Strings continually reconnect and vibrate in specific ways in becoming the fundamental particles, such as electrons, photons and gluons. It is mind that controls what vibrations (vibrations are what makes a thing, a thing, whether it's concrete, fingernails, thinking, eyes, everything) manifest into the world we know as physical. Here we have a glimpse into the workings of the mind of the Great Infinite One. Amazingly, humans have a means of connection into this energy field.

The heterotic (expressing contrast, comparison; hetero is Greek for 'combining two, usually or more, different things {example, 'heterosexual'}')-string theory attempts to explain the types of particles we observe. A string of particles with two different dimensions associated with it is heterotic; in this case, spaces. It's a mathematical universe.

The fields that describe the physical degrees of freedom of the string in its ten dimensional universe can be divided or decomposed into two independent parts; one part moves clockwise and the other, counterclockwise around the string.

String theory suggests that energies beyond 10 to the 18th GeV have no meaning. Some strings possess special dynamics as they carry electrical currents. Why some do and others not poses a conundrum. The energy propelling high energy particles remains a riddle as nothing presently detectible is near (out there in space) that can be quantified. 

Astrophysics is currently unable to provide answers: As Ludwik Celnikier, Observatoire de Paris-Meudon said regarding a comparison of dark matter to ultra high enery cosmic rays, in the article 'Superconducting Cosmic Strings' in American Scientist.(americanscientist.org), May/June, 2000."The former is a form of matter which should exist, but until further notice, doesn't, whereas the high energy rays are particles which do exist but perhaps shouldn't".
   String theory is challenged by quantum theory.
