Retired experimental particle physicist.

The picture is a fayum . It looks like aunts and cousins of mine :).

This is part of the ongoing analysis of LHC data on ATLAS and CMS. example arxiv.org/pdf/1307.2518.pdf

comment Producing photons with same frequency, different amplitude wave
@BenCrowell I am responding to the question, where amplitude is connected with energy , that is why I put the quotation marks. I give the link where a quantum mechanical amplitude is of course defined, in case the questioner is more sophisticatedin physics than the question.

@CuriousOne good point, I will add it.

comment About the Large Hadron Collider
Yes there are quantum field theoretical models that are incorporated in generators of Monte Carlo programs that simulate the real data. Differences show where theory has to change.

comment How to understand “always create before we annihilate, not the other way around”?
an annihilation on the vacuum is pointless?

comment How do test lights (mains tester) work?
Please note that it is the voltage that is necessary to be high enough that the energy levels in the atoms in the media making up the test lamp can be excited and release photons . Static electricity can give high voltages but very little current.

comment Is this summary of modern theoretical physics correct?
@CuriousOne I agree, but people are people. I have lived through the Regge pole season, the four fermion interaction, the vector exchange models, the parton model, the eightfold way, fially convergin to the standard model and looking beyond the standard model. it marches on.

comment Is this summary of modern theoretical physics correct?
@CuriousOne it is a description of what the majority thinks and expects to find/constuct in the future. As with all consensus views it could be that this will not materialize.
