It’s also debatable whether virtual particles and atomic decay are examples of “uncaused events.” Some interpretations of quantum physics describe events without causes, but others, such as the interpretation offered by the late David Bohm, include no uncaused events. Under Bohm’s view, (or the de Broglie-Bohm interpretation) the way particles behave or act is completely determined by the physical events that happened earlier in time. The eminent quantum physicist John Bell has praised this interpretation and laments the difficulty quantum researchers have in developing models that include truly free or random observers. He writes, “It is a merit of the de Broglie–Bohm version to bring this [non-locality] out so explicitly that it cannot be ignored.”The fact of the matter is that there is no consensus on which physical interpretation of the equations in quantum physics is correct and, more importantly, our inability to find a cause for quantum events no more justifies the conclusion that there are no causes any more than our inability to detect alien life justifies the conclusion there is no alien life in the universe.
