Ultimately, there’s no difference between asking ‘how’ something works, and ‘why’ something works. The ‘rules’ by which existence operates are in place; and (really) at our current position in the scheme of things, the ‘why’ of it can only be explored by first explaining ‘how’. The ‘how’ of the universe simply exists. ‘How’ was not instituted after consultation with a focus group. No central committee had a go at the rules, at which time they were posted for public comment. No one gets a voice on ‘how’, nor is it subject to a recall vote. It’s up to us to discover that ‘how’, to the best of our ability. Still… ‘why’ isn’t a question you can profitably ask from within the experiment.
