photon pairs
« on: 28/07/2007 21:04:38 »
Sorry, mainly questions!

Is there any evidence of photon pairing?

If photons have no mass and can occupy the same space at the same time could they initially be produced in pairs?

In other words, could the photon have a double but because the double occupies the same space we don't notice?

Thanks in advance... [;D]

You could produce photons in pairs such that the two photons are identical and lying on top of each other.  However, as far as I know, there shouldn't be a problem in noticing that you have two photons.  If you put a bunch of partially reflecting pieces of glass in the path of the photons, at each mirror, each photon has an independent chance of being reflected or transmitted, so at some point, you'll be able to see one photon coming back at you in reflection, and one photon going forward in transmission.

Thanks jpetruccelli  [:)]

It was reflection that I was thinking of and especially your last part!

I'm trying to say that there is no such thing as a single photon and that they are always produced in pairs that occupy the same space.

If 2 photons were being produced perhaps both get absorbed but one then gets re transmitted again as a photon.

Maybe this should have been put in New Theories?
