“If different physics is ‘all’ you want, you can look (say) to Einstein’s theories of special and general relativity, in which motion and gravity slow time and bend space. That’s not easy to imagine, but I reckon you can do it. You just need to imagine time passing more slowly, distances contracting: distortions of your grid references. You can put those ideas into words. In quantum theory, words are blunt tools. We give names to things and processes, but those are just labels for concepts that cannot be properly, accurately expressed in any terms but their own.” — Philip Ball
