Neutrino in the space

[czeslaw]

Neutrino is not an electromagnetic wave , though do carry some energy.
Neutrino do not react with a photon or electron.
Neutrino is emit during decay of the particle. It changes the rest mass of the particle when absorbed. Creation and decay of the particles with the rest mass is balanced by the neutrinos.
Neutrinos may join together and change their energy (oscillation of neutrino).

Why don’t we see any neutrinos from outside of our Solar System, according to the number of photons from Background Radiation ?
Every Black Hole produce billions times more neutrinos then our Sun.
How behave a cluster of the neutrinos?
Does exist a Super Monster Neutrino bigger then the Taon Neutrino? May they form a Whirlwinds of the neutrinos?
If neutrino carry some energy, so do it possess the rest mass as well?
Do neutrino act with gravity, or with repulsive force, a kind of pressure, like antigravity ?

I thought that electrons and neutrinos can interact by weak interaction.

Why should neutrinos depend on the Cosmic Microwave Background?

Definitely interacts with an electron, or more specifically an electron anti-neutrino interacts with an electron via the weak interaction.

I'm not sure about the CMB bit, but we have detected neutrinos from outside of the solar system. The example that I'm thinking of are those detected that were produced by supernova SN1987A.

[Ricimer]

1) We do see neutrino's from outside the solar system. They just aren't common.

2) I ask you this, go outside and find a streetlight. Now, look at the stars. Which one do you notice? The light? or the stars? Ans: streetlight

Now, which one actually puts out more light? Ans: Stars

Why do we notice the light more: Ans: It's a lot closer.

Same thing goes with other neutrino sources and why we notice the sun more than those.

Neutrino's barely interact with anything, a cluster of neutrinos would be highly improbable. If they did exist, they'd behave like any other cluster of objects bound by a force.

Neutrino's are believed to have some mass.

A neutrino is not a force, it is a particle. As such it reacts like all others. however its small cross section and neutral charge means it doesn't really hit things very often.

[czeslaw]

The weak interaction between elementary particle (in a range of about 10^-17 m) are involving neutrino (the boson W or Z decays to lepton and its neutrino).
This means – there are produced enormous number of neutrinos, and only some of them are scattering on the particles. Very, very little on electron.
The most neutrinos come to us from our Sun. A little bit come from Supernovae outburst. Where are going the neutrinos from the Black Hole in our Milky Way?
Does it means the Cosmic Voids are filed with neutrinos ?
Neutrinos may oscillate and they have different energy, are then a Super Cluster Neutrinos?
Different energy means the mass in Standard Model. What kind of mass have neutrinos if they are not electromagnetic wave? How do they behave gravitationally ?
The neutrino moves with speed of light and surely is a wave (some kind of energy), not the particle as electron. But, is it possible in some conditions a resonance oscillations of the neutrino (similar as the photons) to create a particle moving slow?

[Ricimer]

Neutrinos move at speeds approaching the speed of light.

They behave as particles for the most part (though particle wave duality says all particles can behave as waves, and vice versa).

As for where the neutrino's from other sources are: See my last post. They're there, but we are merely blinded by the sun's emissions of neutrinos.

So most detected neutrinos come from the sun, yes. That doesn't mean most neutrinos are created by the sun, or come from the sun.

The universe is indeed permeated by neutrinos.

If they have mass, they behave like all other particles with mass, in all respects.
