Explanation: From where do these neutrinos come? The IceCube Neutrino Observatory near the South Pole of the Earth has begun to detect nearly invisible particles of very high energy. Although these rarely-interacting neutrinos pass through much of the Earth just before being detected, where they started remains a mystery. Pictured here is IceCube's Antarctic lab accompanied by a cartoon depicting long strands of detectors frozen into the crystal clear ice below. Candidate origins for these cosmic neutrinos include the violent surroundings of supermassive black holes at the centers of distant galaxies, and tremendous stellar explosions culminating in gamma ray bursts far across the universe. As IceCube detects increasingly more high energy neutrinos, correlations with known objects may resolve this cosmic conundrum -- or we may never know.

Oh Noooos, If John Kerry’s “seismic challenge” doesn’t get us the Neutrinos will. We’re DOOMED! :)
Interesting neutrino fact:
Every second, day and night, month for month, year for year, approximately 70,000,000,000 (70 billion) neutrinos pass through every square centimeter of YOU.
If that makes you feel icky, a shower won’t help.
They ASSUME these nutrenos are from the Big Bang, etc. they actually can’t tell the difference. Jut more push for more funding.
Must be the second stargate.
The would be an interesting neutrino surmizing. Neutrinos cannot be directly detected so it is speculation and observation of effects. And since neutrinos carry no charge, the only detection or observation must rely upon the neutrino to carry some minimum level of energy, which kinda goes against the definition of neutrino... Kind of like catching a breeze with a salmon net.
According to FermiLab, you're off by a factor of about 1,000...
From FermiLab:
Our universe is permeated with neutrinos — nearly massless, neutral particles that interact so rarely with other matter that trillions of them pass through our bodies each second without leaving a trace. These tiny particles, studied in world-leading Fermilab experiments, could be key to a deeper understanding of our universe.

“Fermilab is managed by Fermi Research Alliance for the U.S. Department of Energy Office of Science. FRA is a partnership of the University of Chicago and Universities Research Association, Inc., a consortium of 89 research universities.”
Oops! Sorry. FermiLab of course actually said trillions pass through our *entire bodies*, not just square centimeter, or square inch.
Solar neutrino flux, which most of it is here on earth, is readily calculated from the observable reactions taking place in the sun. Mostly the proton-proton reaction, each of which yields one electron neutrino.
I said *per square centimeter*. Add all those up and I'm pretty close again.
OK, you caught it too.
If they’ve been traveling a long time, wouldn’t they turn into oldtrinos?
Neutrinos don’t get old - they just die when they’ve reached the outer limit of the universe.
