Fotons influence from long distance

[Olli Santavuori]

It is not so mystical that fotons have influence to each other in long distance because also gravity has a long distance efect.

[Schmelzer]

I don't understand. This subforum is about quantum theory, and there is no established quantum theory of gravity now. So what are you talking about? If you talk about classical theories, as EM as gravity are described by Einstein-local field theories, thus, without long-range influences.

[Olli Santavuori]

In quantum theory some photons are working together in long distance, have I heard, without being an expert. Some philosophers make mystical thoughts of that empirical fact as also of some other conclusions of quantum theory. Gravity is a force between particles regardless what different theories say of its nature.
