    Higgs particle, supersymmetry and dark matter.

    Hello humanino, The reason why I stated that was that you seemed to be claiming that light sparticles may not be dark matter because they might not be stable. I said, that would need to be accepted with the claim that all dark matter is stable. But we don't know that. It's possible that...

    Higgs particle, supersymmetry and dark matter.

    Hello humanino, I never said that all dark matter is made up of superparticles. I said that superparticles are dark matter. Me having to accept that the lightest supersymmetric particle is absolutely stable is the same as you having to accept that all dark matter is absolutely stable. Even...

    Higgs particle, supersymmetry and dark matter.

    Jorge, You're saying dark matter and supersymmetric particles like they are two different things. Supersymmetric particles, if we do find out that they exist, are dark matter. Because sparticles are massive, weakly interacting, stable, and neutral. Exactly what dark matter is. Maybe you...

    Ionizing particles (alpha & beta)

    I think I understand the impact that an alpha particle can have on living tissue. Not having electrons in it valence it would be very reactive - stripping electrons from atoms or molecules it bumps into (assuming it made its way in a biotic host). But how does a beta particle ionize an atom...

    Radioactive Decay - Beta Particles

    Thanks again for the responses! Alot of things are getting cleared up for me.

    Do particles exist forever? Can Anything Exist forever?

    Why do neutrons decay so readily when not confined in an atomic nucleus? Does strong nuclear force help prevent their rapid decay?

    Radioactive Decay - Beta Particles

    Hi jtbell, I don't mean to be a pest. But could you explain/define the terms being used? I'm a novice's novice when it comes to this. Thank you very much.

    Radioactive Decay - Beta Particles

    Thanks for the answers. But I'm alittle bit confused now. Initially I thought that when a neutron decayed to a proton that it also released (as stated in the replies) an electron and an anti-neutrino. I was talking with a condensed matter physicist and got chewed apart for saying that. She...

    Radioactive Decay - Beta Particles

    One thing that is really confusing me is Beta Particles. This site states that Beta Particles are electrons that are shot out of the nucleus (atomic core) of an atom. http://home.clara.net/darvill/nucrad/morebeta.htm To rationalize this claim it states that a neutron will decay to a...

    Neutron causing Nuclear Fission how?

    Thanks for the answers. Making a bit more sense now.

    Neutron causing Nuclear Fission how?

    If anyone can help me with this question I'd be greatly appreciative... Here's what I think I understand: Nuclear fission is the breaking of an atomic core of an atom. Like with U-235. It absorbs a slow moving neutron which yields the unstable U-236. Because of the instability the atomic...
