The behaviour of sub atomic particles is bizarre, and as JTP says, some theories are purely mathematical, but are nevertheless accepted.
However, the further this knowledge is pursued, it seems to me, the more there is an underlying force / purpose, call it what you will, that at least in secular terms, verges on the religious, or maybe the philosophical. Are we now not getting to the point where it is impossible to widen our understanding, but simply appreciate the effects observed, not having an inkling of the cause?
Something similar is happening in prophecy / futurology, where too many correct predictions occur to be written off as coincidence, and the latest of these is the web bot as on the link.
The effect is there, with varying degrees of accuracy, but the cause is not apparent.
