Starship Asterisk*

Hello

Lets think of it this way.

How many neutrinos make up and electron?.

How many electrons make up a quark?

How may quarks make up a Neutron or a proton?

Now! what is the building blocks?

Where is Mass added?

Three quarks to eack proton and neutron - there only stable in certain combinations.

Quarks and Electrons are completely unrelated - electrons are fermions.

Hello

no!!!!!! all matter and energy are related in one way or another.

Each partical will have its own properties.

But! they share a common origin in the never ending recyclic process.





Have a nice day

Sorry Harry, yes you're correct in what you say, I meant they are not related in the sense that one is not made out of the other.

Most people use the String Theory to explain the minimal makeup of the universe.
The string theory also can explain the "Non-conservation" of mass and energy seen in accelerometers. To make a long story short, total mass/energy are not always conserved in atomic collisions, small amounts of mass/energy may be lost in the initial collision but second to minutes later a "Phantom Partial" can appear in the detector out of nowhere. It is believed that energy was temporarily pushed into one of the non-perceivable dimensions. This opens a whole new can of worms I'll get into later when I have more time.

agree with you.
But! neutrinos have three charges + , - AND NEUTRAL.
As a matter of opinion.
If an object has charge and size don't you think it may have mass.

do neutrinos have a charge? an electrical charge? i don't think they do.

No, they're a chargeless, possibly massless, particle (hence the name!). Usually when you talk about neutrinos you're referring to the electron neutrino.

so they don't have a charge

No they don't - don't quite know where Harry got all those charges from!

Supersymmetry suggests that there are lots of 'inos', this is a possibility for the strange dark matter. I believe (I mentioned in a previous post) that the theorectical photino (photons' 'ino') would be stable in an ingalactic space environment... but who knows eh?!

Hi all, long time listener, first time poster. Love your work and happy to see people discussing science without having to do so through a wad of PHDs and so forth (with, of course a deferential nod and tug 'o forelock to those of you who possess same)
I just wanted to know what the gathering thought (I guess you saw it when it came out, but I was reminded of it when reading this article "Mini-galaxies may reveal dark matter stream" in NS) of the claim that dark matter has been definitavely detected.

article linky hereThat was in 2002 - has there been refutation of this?

I've seen the topic but I haven't read this article - yet, looks interesting. I'll let you know what I think once I finish (spare time is short).

Refutation? It's hard to find anything that isn't being refuted by someone.

And welcome Dogshead!

Does a Neutrino have mass ?
Does it have a charge?
Can it be neutral?

The question is can man at this present time detect its properties?

Does a Neutrino have mass ?

Current thinking is that neutrinos must have mass to show the oscillations that have been observed, so yes neutrinos have mass.

Neutrinos don't have electric charge, they are neutral particles (if they had a charge they'd be a hell of a lot easier to detect!!!!).

Can it be neutral? Yes.

OK

Some say they have Mass
others say they do have a left and right spin and a neutral charge

I think we will have to wait for more tests and with lots of salt.

By next year with more tests they will probably re-define the neutrino.

I think they do have mass and have different spins meaning a negative a a positive charge. If the problem is deducing the spin than a neutral charge.

It is very likely they'll have spin as all particles do, but thats no indication that they'll have electrical charge. I'll tell you now it is physically impossible for the neutrino to have a charge - PHYSICALLY IMPOSSIBLE!!!!!

Don't think you're understanding spin there Harry - you don't get left/rigth spin, you have spin values of 0, 1/2 and 1 and multiples of....

If its physically impossible for a neutrino not to have a charge than it has no mass.

A neutron has no charge and yet has a mass. A neutron is a formation of 3 quarks, a neutrino is much much smaller than a quark, it is also much smaller than an electron, a neutrino's size scale is so small they can pass right through atoms and only about one in 10 X 10^28 will knock one low energy photon from the atom.

It's true that all matter can be expressed in eV, (electron volts: E=MC^2), that is not the same as having a charge; a charge is the interaction (attraction and repulsion of particles) by the electro-magnetic differential between them.

I think you maybe right.

I think you might be getting it!

smile,,,,,,,,,,,,,,i get some sometimes.

I found this site to be interesting.

I read that link, it is so boring. They speak of early universe and expanding universe it is double dutch.

I have emailed the writer of the link to confirm some issues


Have a Nice Day

i thought it was a very interesting article, there are some good results coming from dark matter lensing approaching too.

Is it boring because it contradicts your philosophy? And from he who always speaks of keeping his mind open....
