... can be reciprocal. I am amused that scientists have finally gotten around to noticing something that is mentioned in many mystical systems around the world. And quantum mechanics, of course, where scientists have spent decades staring at the double arrow moaning "That can't be right!" instead of asking "How could this be right? What would it look like if this bit of science applied to some parts of the world? Can we find any examples of reciprocal causality?"
Dudes. If you're doing science, you have to actually do the science. You can't just ignore parts that make you uncomfortable.
