Physics, Astronomy & Cosmology / Re: How many neutrinos are orbiting the Earth?
« on: 14/03/2016 00:57:09 »The final results of the OPERA experiment showed that neutrinos are traveling so close to the speed of light that you cannot distinguish the two.Man made neutrinos may have nothing in common with the naturally occurring phenomena.

However, neutrinos will lose velocity due to the general expansion of the universe. The speed of these cosmic neutrinos follows a thermal distribution. It is thought that they will have an effective temperature of around 2K (slightly cooler than the 2.7K CMBR).
There is very no verifiable evidence to support the conclusion that the Universe is expanding. Less evidence to supporting such phenomena would have an effect on neutrinos.
Neutrinos, by definition, are nearly impossible to detect, let alone observe. There is evidence that they are produced at supernova episodes. They were detected near the time of SN1987A. But the data are limited.
WIMPs - Weakly Interactive Massive Particles aka Neutrinos are believed to be passing through us, the planet the solar system, the galaxy and more or less everywhere.
Counting or even estimating the amount in orbit is impossible, with present technology.
Most would likely be found near the super massive blackholes in the centers of galaxies. I suspect the odds would suggest there are some orbiting Earth. More orbiting Jupiter and more still, orbiting the Sol.
Oddly enough, some of their orbits may pass through the bodies they orbit, because they rarely interact with baryonic matter.
