Abstract
The posed question, “What’s ultimately possible in physics?” is interpreted. Its full content is argued to be: Who or what is ultimately or may ultimately not be directly or effectively allowed to shape, access and exploit whatever physics will ultimately become? An answer can only be given within the constraints on the possibility to engage in a meaningful discourse about such a subject matter. This essay directly probes today’s limits by presenting those responsible for the selection process with a kind of catch 22 situation. Not only to establish this probing, but also in order to ensure relevance by discussing actually likely scenarios, we turn towards uncomfortable aspects that may be characteristic for what is ultimately possible in physics. The focus is implicitly on the necessity of selection and on consistency with the morphology or structure that is naturally expected from mutually co-evolved systems. Some concrete example scenarios for what is ultimately possible in physics, especially regarding the ultimate role of physics, are presented.
