Things you think about in Slough

Gravitons on a small scale

Finding myself in Slough (England) with very little to do I got thinking about spin again. I say again, because I did a little post on spin a while back. 

I can't help thinking that the great mysteries of the universe will be unvailed once we have a proper handle on spin. Anyway, here I am in Slough, won't bother explaining why I am here, other than to say tomorrow I get a train back to London. Oh happy days.

So spin.

It occured to me that the effect we call gravity is not actually dependent on mass, but rather on spin.

Mass certainly exists (at least I think it does for now) and this is one of the properties of matter that make it distinct from electromagnetic radiation. But here is the thing. Protons, electrons, photons etc all spin and so all have gravity.

Even though a photon has no mass it does have "gravity". Of course this means that the term gravity has a different meaning here from traditional gravity which is linked to mass.

So, here are some things I will be thinking about on my train back to London tomorrow.

If photons do have gravity is it related to the photon frequency? If so then won't xrays be deflected more that light rays when they pass near the sun?

Do neutrinos actually have no mass,  travel at the speed of light, but have enough spin to have gravity?

If we accelerate protons to almost the speed of light is the increase in mass actually an increase in spin?

Are neutrinos actually gravitons? don't know where that one came from! will give it some pondering though.

Looking forward to the journey.
