As for the interaction happening at a single vertex: Feynmann diagrams are drawn with space on on axis and time on another, so we have an interaction that requires 1/infinity in both time and space. Since infinity is non-physical the Feynmann diagram is wrong!
At the vertex you have to have...
What good would that do: I can't remember any of the happenings in the abductions.
It does: how else is Nature to come to a decision to allow an interaction or not? If you say objects just responds to space and fields: that is still a computation.
Of course it computes: particles with one set of momenta don't transform while the same type of particles with a different set of momenta does. This happens continuously.
Nature can calculate fast but not instantaneously: how would that work? Even if the computation is hardwired into space, because it must be encoded generally, it must take time. Specify any calculation and I can guarantee you it takes time to execute: at the very least a number must be read into...
According to you: at a single point in time, Nature has to decide to allow the transformation or not: this is not physically realizable because a computation has to happen and that takes time: so an instant transformation can't happen. I have explained how the computation happens: you can't do...
