The structure of the photon (here meaning the fact that it can fluctuate into an electron positron pair) is what leads to the speed of light being c and not something even larger. So your intuition is somewhat correct, except that the effe

Not a stupid question. However, I think that this process (whether it is included in calculations or not) shouldn't contribute to the dark matter issue. Electrons and positrons are "normal" matter and if they are anywhere nea

Author here, thanks! I am not familiar with this website (science-news.co) so I cannot comment on the quality of the writing (or human origin). I agree with you that "prove" should be "predict" - they did not prove anyth

In classical electromagnetism photons (light) do not interact, period. But in quantum mechanics the photons can briefly fluctuate into electron + positron pairs which allow them to interact with each other. But the probability for interacti

One of the authors here. You are correct, the famous SLAC result already demonstrated that light can be converted into matter, but they needed several photons >4, average of about 6 - that is the so called non-linear Breit-Wheeler (BW) p

The Breit-Wheeler process (convert two photons into electron+positron) has been one of the most elusive fundamental processes in electromagnetism. This prediction came when quantum mechanics was first being developed in the early 1930s but
