[9] After opening, keep bottle tightly closed between uses to protect from moisture. The lowest nonzero-mass particle we know of is the neutrino, Lincoln said. A proton is smaller than a molecule. Heisenberg's uncertainty principle states that A proton has a much smaller cross section than that, and the quarks and gluons, of which the proton is made, are even smaller. Although the Model assumes the existence of a graviton, all attempts to produce a consistent theory based on them have failed.
Scientists have a good idea of how quarks make up hadrons, but the properties of individual quarks have been difficult to tease out because they cant be observed outside of their respective hadrons. Quarks are fundamental particles and cannot be split. Many of the preon models theorize that the apparent imbalance of matter and antimatter in the universe is in fact illusory, with large quantities of preon-level antimatter confined within more complex structures. What is smaller than a preon? The metal opening is 1/4"-1/2" inch wider than the 2.5' - 3" inch conduit allowing weather to infiltrate area. Theres never been any evidence that theyre made up of anything at all. Ans. A preon star which is not really a star at all would be a chunk of matter made of these constituents of quarks and bound together by gravity. In the Standard Model, there are also bosons, including the photons and gluons; W+, W, and Z bosons; and the Higgs boson; and an open space left for the graviton. So why is the Planck length thought to be the smallest possible length?
