Sort of off topic, but sometimes pondering these low-level physics questions forces me into a philosophical state of mind. It seems like asking questions about basic particles is representative of a mode of thinking that drills down ever further, trying to find some kind of conceptual bedrock. But it always seems possible to ask again, "What lies underneath this? What is the cause of this thing's existence?" In any case, it seems either that you have found the one thing that underpins everything else or you have found the collection of things that all endlessly perpetuate each other. Both of those possibilities seem somehow unsatisfactory or impossible. There must always be something else. Could it be that this conceptual craving is somehow just a side effect of how our minds are built? Or is it fundamental to reality in some way?
