Thats what I was trying to tell Prof. It seems that neutrinos should have mass (albeit small)..

In fact, according to hyperphysics the neutrino was first postulated to make up for the energy gap in beta decay (the decay of a neutron to a proton via the weak force). Of course, if the neutrino really does have a nonzero mass then it will interact via gravity too, but this will be extremely weak.

Neutrinos must have mass. Any particle (energy or matter) that exists must have mass. It may be negligable, but it's present none the less.

It all boils down to E=MC^2

If E>0 then M>0 because 0 x C^2=0

We study them because they are the basic building blocks of atomic matter. Although not entirely relevant to Profpat's idea, they are an integral part of subatomics.

Well thank you everybody for your input.
Here is part of my problem with the neutrino, It doesn't appear to have any interactions on its own.

If it has mass, then there should be interaction with massive bodies, such as the Earth and Sun, but aparently it goes right through them.

Even the photon which is massless and chargeless has reactions with its medium, that is why the photons stay within the sun, and the photoelectric effect it has on electrons.

But the neutrino has no such interactions that we are aware of. Why is that? Does it truly exist?

My philosophy is this;

"It's here, it's queer, get use to it."

But in the meantime I am ignoring it.

Best to all,

Hi Everybody;

Pondering on my above post last night, I was thinking that perhaps our mysterious neutrino could in fact be an example of the elusive string?

The string being a theoritical one dimensional entity would have the ability of going through everything without interaction. the string could have a small amount of mass.

The photon is a 2 dimensional wave/particle and therefor interacts with other particles.

If the neutrino was a 2nd or 3rd dimensional entity it should interact. If it's 0 dimension it doesn't exist. What is left is a 1 dimensional entity like a string.

Just some thoughts on the subject of neutrinos.

Best,

Pat

Dont do it Prof... probably there is some basic characteristic of neutrinos that we dont understand and it could unravel a lot of myths... stick to it chum.. dont give up..

OK Dipayankar;

Maybe together we can make some sense of the neutrino. What did you think about my thought that it could be a 1 dimensional entity and therefor little to no interaction ?

[dipayankar]

I just read an article in The Telegraph that maybe time is slowing down. Which means that to keep the equilibrium, space is accelerating. Hence the question of Dark energy can be eliminated.

If time can come into existance as a dimesnion during Big Bang, then it will also cease to exist one day, why cant it accelerate or slow down like a dimension of space? Just my thoughts here...

You may have something there Dipayankar. I forgot time is not linear, but curved, with the space/time fabric.

Moreover, Einstein postulated that time is not linear across the universe. It varies minutely but measurably depending on the speed and the perspective (the frame of reference) of an observer relative to the object that is being observed (in its frame of reference) and its speed.

There could indeed be the relationship of time slowing down as space acclerates, because they relate to each other. Only the interval between space/time is absolute.

BEST TO YOU,

Yes so there can we somehow fit in Quantum Mechanics??

Good question Dipayankar;

I guess the quanta of space would be plancks length, and the quanta of time would be plancks time. But there could be something smaller. In the void the entire void would be the quanta and there would be no time as there would be no movement. But space/time is made up of the ether, which would be E/M waves and perhaps gravitational waves.

Best,

Pat
