The elementary particles from which the Universe is built. Six leptons and six quarks are most of the matter; such as, the protons and neutrons of atomic nuclei are made of quarks, along with the electron is a lepton. These particles interact by using the gauge bosons shown in the middle row, Just about every corresponding to a particular form of gauge symmetry.
By definition, there is not any way for everything in a single universe to have an effect on some thing in Yet another. The multiverse is just not still a scientific idea due to the fact there is absolutely no way to check it. An strategy that cannot be examined or is not really depending on logic will not be science.
