Title: Does the proton have the Planck charge?
Post by: jeffreyH on 31/12/2014 14:48:10

I read this and found that since the proton obviously does not have the Planck mass there is something fundamental here if it is true. This is even more significant since the electron has less mass but an equivalent and opposite charge.

If I understand correctly, the Planck charge (http://en.wikipedia.org/wiki/Planck_charge) is around 11.7 times larger than the charge on the proton and electron.

That makes it around 17.6 times larger than the charge posited for quarks.

The Planck units were selected to be independent of any physical particle or object, so it is not surprising that the Planck charge is different from the proton charge. But if it makes you feel any better, the charge on the proton is roughly within an order of magnitude of the Planck charge (to use a very human measure)...

It wouldn't make me feel better or worse. I was simply trying to confirm or reject something I had read stated as if it were fact. I couldn't see how it would be correct as it would be a major coincidence.
