Simultaneous Causation

[Atype*]

I have seen some philosophers discuss the concept that an effect and its cause can be simultaneous with one another:

However is this a concept that is demonstrated by experiment? Is entanglement an example of this? If not why not?

This is the wrong forum for entanglement. That would be the "quantum physics" forum. In classical relativity, cause always precedes effect, with one gray area. In GR there are mathematical solutions with closed timelike curves. On these, locally, cause precedes effect, but globally, you can argue you have effect preceding cause.

As for entanglement, there is no cause effect relationship. There is a myserious correlation at a distance, but not cause effect.
