On a related matter, does QM allow for the coming into existence of a particle without there being a cause? I think I can understand that there are causeless events but can we allow for the arisal of a particle without there having been a cause?

Thank you for the kind welcome. And thank you for your enlightening answers. I had the sneaking suspicion that it was fair to say that there are events, in the quantum world, for which a cause cannot safely be attributed. It seems, reading from the replies, that the statistical/random...

Thanks everyone for some insightful answers. After reading I realized I hadn't really completely stated why question. I am interested in whether or not for all effects that occur, there is always a cause or whether some effects are causeless. The example of the radioactive decay as gives...

It is my understanding that in classical mechanics, cause and effect are universally accepted. Is it the same in QM? Is causality sound in QM?
