Yes, that is my understanding. See the link given by Dimitry67 in the first reply to this thread. That was the source of my information about the Oh-My-God particle. I didn't mean to imply that it was a photon - merely that the energy of the most energetic photons observed in your citation was...

I would have to question your interpretation of this very interesting article you cited. In citing the figure 2.2 EeV, I think you must be referring to Figure 3 therein, but the scale there is Log(Energy/EeV) - not Energy/EeV and the anti-Log of 2.2 would give an energy of about 158 EeV for the...

Does anyone know how energetic the most energetic photons ever detected from a natural source were and what their source was?

No comment.

I feel that I need to back up and clarify a couple things. First, I understand that practicing physicists and mathematicians are accustomed to "simplify" their notation by any and all sorts of conventions and omissions but, just as Alfred Tarski once decried the sloppy notational practices of...

Gaussian units Was I NOT careful about my electrical units? The Gaussian system of units uses cgs-electrostatic units to measure electrical quantities and, in cgs-electrostatic units, epsilon is, indeed, 1 while mu is 1/C^2. On the other hand, the Gaussian system of units uses...

Everyone "knows" that the fine structure constant (alpha) is a dimensionless number, but I am troubled by the fact that the Planck unit of resistance must be one - if that is true - and that strikes me as suspicious. I wonder if anyone can shed any light on this. I present the complete...
