Vacuum and Light
Vacuum and Light
It occurred to me that since a vacuum is full of pairs of particles coming into existence and then being destroyed, as it borrows some energy for a some time, whether the existence of light traversing a vacuum in some depends on these particles for some ( or all ) of its properties.
One might only be able to test this very close to a singularity / black hole. Indeed might light be reflected from a singularity.
Not my field, as you can tell
I think that this is also related in some way to the thought that a photon actually can only interfere with itself, and not with other photons, but this might break down if two intereacted with one or both virtual particles
