text: even though quarks are the smallest indivisible particles they should b made up(see +details 4 cmplt qstn)? they should b made up constituent particles. which in turn must be made up of constituent particle. therefore every resultant particle is a constituent particle on it's own. therefore if we stop subdivision of matter doesnt it mean that the so called smallest particle is not made up of anything else?and if it's so,doesnt it mean that it cant exist without a subparticle??and this means that stopping subdivision of particle means simply wiping out it's existence...umm am i right?(i want an xplanation for ur answer by the way not yes or no) there is no definite answer to your question, since science has a limit to how small particles it can detect.  the basic theory in this area is that matter is just a standing wave.  a wave has no weight, but when encased in a sphere, it then has mass.  and mass requires weight.  this weight is so infinitesmally small it cannot be detected.  but these spheres, called photons, are held together with other photons making up quarks, which are held together by glueon, which in turn makes up atoms, etc.  this is all based on the wave/particle duallity of light.  for more info on this, just e-mail me at msm0021@hotmail.com.
