About seven years ago, scientists found the tau neutrino, which is a fundamental building block of matter. It is the final building block. It took six million tries to find the four events that proved the tau neutrino exists. The magic number of building blocks of matter appears to be six. That is, there are six quarks, and six leptons. The tau neutrino, which is a lepton, was the last of the dozen. The tau lepton, which is what the tau neutrino becomes, after hitting an atomic nucleus, such as iron, quickly disappears. The only evidence the tau lepton leaves is a one millimeter track.

Not to worry though, that tiny one millimeter track probably has many billions of smaller super particles, enough to keep scientists busy for at least a hundred years of searching. These super strings might be the dividing line between hard physicists who do not think they exist, or at least can never be proven to exist, and a more imaginative set of scientists. This imaginative set of scientists, perhaps we could call them string theorists, may need to find a different name for their type of science. Physics seems to be taken by hard matter. Super strings are probably not what anyone would call matter. They may be pure energy, a term that Spock used in the original Star Trek series. In fact, super strings might be locked up forever in a world of science fiction, the quantum world, where everything that can happen does, and even that which cannot happen happens. I think this might be what motivated me to write my movie script, or at least the story line for the script. I needed a professional ghostwriter to actually produce a screenplay.

The first lepton discovered was our old friend, the electron, about 1897. It took forty years to find the second lepton, a muon. Another forty years to find the tau lepton in 1976. The tau neutrino showed up about 24 years later, in 2000.

The tau lepton is the only one that can decay into hadrons. This might be a good point at which to say: I do not have actual knowledge of any of this evidence. I only know what I am told. So I have included the links to these ideas and discoveries for anyone to follow their own trail of particle physics, and string theories.

Happy Hunting :) String Theory: http://www.mkaku.org/

Oh. I almost forgot, hadrons are a mixed bag of matter and energy. Fermions, named for my hero, Enrico Fermi, and bosons,
