The Standard Model of particle physics is a theory of three of the four known fundamental interactions and the elementary particles that take part in these interactions. These particles make up all visible matter in the universe.

Every high energy physics experiment carried out since the mid-20th century has eventually yielded findings consistent with the Standard Model.

Still, the Standard Model falls short of being a complete theory of fundamental interactions because it does not include gravitation, dark matter, or dark energy. It is not quite a complete description of leptons either, because it does not describe nonzero neutrino masses, although simple natural extensions do.

NEUTRINOS

The particle itself is a fundamental particle and is too small to be seen by any imaginable instrument of observation. So we instead represent the property that allows the neutrino to interact.

The white area represents the weak charge of the neutrino. This charge - entirely separate from electric charge - gives rise to the Weak Nuclear Force. This force allows the neutrino to interact - but only very weakly and its typical range is much smaller than the diameter of a proton.

Neutrinos are produced when a down quark decays into an up quark, and an electron. Conservation laws require that a tiny neutral particle is created in beta decay and that particle is the neutrino (technically an anti-neutrino)

Because the neutrino only interacts through the weak force (and negligible gravity) it almost never interacts with other particles on its own. Millions of neutrinos stream through your body every second totally unnoticed and unnoticeable.

  • It is possible to theorize that the Big Bang happened before, how many times, we don't know. Consciousness is just the universe discovering itself, it is purely natural. I don't think of God, I think that we are the universe and that in itself, is a spiritual awakening.

  • Then you'd be happy with the "side-hug" neutrinos hypothesized by William Lane Craig.

  • Your vid went viral on PortoNovo

  • Standard model of Physics is already questionable!

  • Neutrinos stream through all matter in the universe....except Chuck Norris. They do not dare.

  • @MrJSabadojr *Update. BOOM! HEADSHOT!

    And explain how that "massive (magical) instrument in the sky" (Flying Spahgehetti Monster) would even theoretically work?

  • lol i watched this in 720p hd and the only graphic is a white dot >_>

  • @MrJSabadojr WHAT?! you utilize the neutrino to build a massive instrument to identify all objects/matter/energy AND YOU USE IT TO PREVENT CRIME?!!?!? WHAT?!! thats like using platinum for jewellery....seriously ridiculous.

  • @MrJSabadojr It must be nice to live in your brain.

  • @MsWanderer1 lol? Ofcourse its fundamental. 

  • I wonder if we can utilized the Neutrino and we can built a massive instrument in the sky so we can able to observe and identify all objects in our entire earth. I f we can do that, we can able to know the total activities of all humans, and by means that we can able to know who committed crime and even locate anybody where ever they are. In that case, Bin Laden can run but cannot hide.

  • The neutrino is not fundamental; the stuff it is made of is fundamental! A real fundamental particle would have infinite mass! :0
