-Neutrino-
It's believed that modern physics nothing can travel faster than the speed of light. The astonishing results of the experiment seem to show that elementary particle Neutrinos, Can. It’s the most spread particles and the lightest. Neutrino is a hardly reacting with matter, It can travel right through the earth without interacting, As an example 70 billion Neutrinos per square second continue coming from the sun. These Neutrino parts traveled through the Earth Crust to the detection point and they synchronized between the 2 points to the nearest Nanno second (A billion of a second) in this distance, they discovered that the neutrino were 60 seconds ahead of what light takes to cover this distance. It's the first time we have an experimental evidence something faster than light and that will make a major change in physics as we know it now.
4. Agenda
• What is Neutrino ?
• What are the types of neutrino ?
• What is the difference between neutrino and
it’s relatives ?
• What makes neutrino fast ?
• How Fast can neutrino Travel ?
• Where we can find neutrinos ?
5. What is Neutrino ?
• A neutrino is a sub atom particle with no electric
charge,
• Neutrinos are known for their ability to propagate
over considerable distances through solid matter
almost unaffected.
• Neutrinos were originally thought to have no mass .
Today they are believed to have mass, but it is
exceedingly small, only a tiny fraction of the mass of
a proton .
6. What are the types of Neutrino ?
There are 3 types :
• Electron
• Moun
• Tau
7. What is the difference between Neutrino
and it’s relatives ?
• The main difference between the neutrinos
and their relatives is the fact that neutrinos
are electrically neutral, while the Electron,
Muon, and Tau are electrically charged.
8. What makes neutrino fast ?
• Neutrinos are electrically neutral, they are not
affected by the electromagnetic forces which
act on electrons.
• Neutrinos are affected only by a "weak" sub-
atomic force of much shorter range than
electromagnetism, and therefore it is able to
pass through great distances in matter
without being affected by it.
11. In the early 1980s, first measurements of
neutrino speed were done using pulsed pion
beams.
The pions decayed producing neutrinos, and the
neutrino interactions observed within a time
window in a detector at a distance were
consistent with the speed of light.
16. Back in September 2011
• in a research project called OPERA.
• The scientists sent a beam of neutrinos from
CERN, to Gran Sasso Laboratory in central Italy.
• 732 kilometers
• they found the extraordinary result that …….
