Quanta Mechanics

Quanta mechanics is literally saying that there's nothing there when you're looking at it. A radical approach is to simply deny the existence of an underlying reality altogether. This would be an anti realist approach to quanta mechanics, since it treats the theory as merely a bookkeeping device for predicting the outcomes of future experiments. All we are ever allowed to talk about is outcomes of experimental measurements. The problem here isn't really one of there not being enough evidence for the radical ness, rather that it's you don't want to accept theradical ness. That's what conda mechanics is. It's extremely radical when you really understand it.
