if quark is the mallest ,isnt light then made up of quarks also?

A photon is a quark, yes-it isnt made of quark(s), it is a type of quark.

yes, Each proton and each neutron contains three quarks.There are several varieties of quarks. Protons and neutrons are composed of two types: up quarks and down quarks.\n\nEach up quark has a charge of +2/3.\nEach down quark has a charge of -1/3.\nThe sum of the charges of quarks that make up a nuclear particle determines its electrical charge. \n\nbut string theory proposes that it gets smaller than quarks a lot smaller. it is interesting and cool to look into.

Protons and Neutrons can be divided into quarks, but electrons are not divisble as far as we know.

Light doesn't have a rest mass, that is an inherent mass that it would have it it were at rest relative to you, but it does have a mass equivalence due to its energy. \n\nE=MC^2 gives the relationship between mass and energy, so you can rearrange this to M=E/C^2 to find the mass equivalence of a given amount of light.  The energy of light can be calculated a number of ways, and then this number can be plugged into the mass-energy equation.  Needless to say, it takes a whole lot of light to add up to a significant amount of mass.\n\nEdit:  Sorry, Mathematician, you're incorrect.  Light does have mass and it can be calculated using the mass energy equivalence.  Your argument is basically circular since you're using the definition of light not having a *rest*\n mass to say that it has no momentum, and the statement that it has no momentum to claim that it therefore has no mass.  You're right in that it has no rest mass, but that's not the only kind of mass there is.  If you've ever seen a radiometer work you've seen direct evidence of the momentum of light.

Light does not consist of proton, it consists of photons which are quantum of electromagnetic radiation, photons have their own antiparticle. Antiparticle is a particle that has the same mass of another particle but its other properties are opposite which result in cancelling the opposite properties. The net result is the production of radiant energy which is light (not according to me, but according to quantum theory). So no question of mass.\n\nAnd light has very high but not infinity velocity, then how would the mass (do not say weight, both are different) be infinite (even if we consider what you say to be true)\n\nProtons are not insignificant, they make up about half the mass of an atom (under normal conditions)

light is energy and, thus, has no mass.

indeed light is as said before photons although according to quantum physics everything in the universe is made from molecules, molecules are made from protons neutrons and electrons and those are made from quanta's.But quanta's are in fact (in a way at least)compressed energy. So you can't really say that they are made from something different technically speaking at least

Matter is something that has mass. Mass, according to the general theory of relativity, is caused by the warping of space. A particle that warps space is said to have mass. These particles are known as matter. The terminology is kind of redundant.\n\nNo one knows what the actual particles are made of. Wheeler tried to explain everything as being a warping or curvature of space. But failed.\n\nThe smallest units of matter, that we know of, are leptons (such as electrons) and quarks.

Corpuscular theory- that light is made up of particles.  Although some ancient Greek philosophers postulated that light was made up of particles, this hypothesis is most strongly associated with Isaac Newton.\n\nWave theory- that light is a wave phenomenon.  Again, many people are associated with this idea, but the first to put it on a solid mathematical footing is Christian Huygens.  Maxwell did not discover the wave theory of light so much as explain it.  He linked light with electromagnetism, by showing that electromagnetic theory predicted the existence of waves with the properties exhibited by light waves.\n\nQuantum theory of light- that light is "quantized", that is, it only comes in certain discrete amounts, and that these quanta, called photons, obey certain probabilistic laws.  This theory has it's origins in the work of Planck, who showed that energy in certain situations was quantized, and Einstein, who applied this energy quantization to light to explain the photoelectric effect.

No, not at all.\n\nProcesses in perfectly stationary nuclei turn mass into energy. For instance, the energy an emitted alpha particle has in alpha decay from a staionary nucleus is reflected by a tiny fall in mass of the nucleus.\n\nConversely, as you accelerate a particle towards the speed of light, more and more of the energy you give to the particle gets converted to mass. In fact, you can never get the particle to the speed of light - its mass will go to infinity first. This is quite measurable in a particle accelerator.

light is a wave-particle duality, and as such does not have 'mass'...

light has no mass, therefore no weight.\n\nHowever, if all the energy of the light were somehow converted to mass, its mass would be m=E/c^2.

Tachyons are faster and smaller than Quarks. Tachyons are not bound to anything related to Time in the Physical Sense. Quarks however generate the Gluon Fields which is basically the Glue of the Universe& the beginnings of Physical Matter on the Sub-Atomic Level.  Since Light as we know it is physical that type of light could not exist there. Thus there is the Darkness God was in before He made the Light exist.

In scientific explanation\nThe basic particle of a matter is atom. Its also divisible but then the properties of that matter will not remain.\n\nThere can also be said every matter is from electron, protons and charge less neutrons. But then it will be devised into light.\n\nIf you look in the vacuum(absence of anything), it should be neither atom nor protons nor something...it should be "ZERO"(which is used to prove a decision "False" or absence of anything).\n\nSay "you have no answer".\nThat means you have zero answer.Think of it, keep trying and make another theory. :-D

If you're referring to a massive object, as opposed to a photon(which is massless), No.\n\nParticle accelerators routinely accelerate electrons or protons to around .99999c (c=the speed of light)and then have them collide with other particles traveling at similar speed. \n\nThe result is a shower of sub-atomic particles, called Quarks and Gluons.\n\nQuantum physicists are busy trying to sort-out this proliferation of particles.  Makes for a lot of PhD theses!

Light is a very odd thing to try and understand.  It behaves as a wave and as a stream of particles...we call this a dual nature.  You just have to accept it, really.  Light is like nothing else for it has no mass and behaves in two different ways.

Quarks are the basic building blocks of some other sub-atomic particles, like the proton. Quarks, unlike other particles, can not be divided.\n\nQuarks are best on crackers with just a dab of peanut butter.
