摘要

While quantum field theory could more aptly be called the 'quantum field framework'-as it encompasses a vast variety of varying concepts and theories-in comparison, relativity, both special and general, is more commonly portrayed as less of a 'general framework'. Viewed from this perspective, the paradigm of analogue space-times (also often called analogue gravity) is to promote the specific theory of general relativity (Einstein gravity) to a framework which covers relativistic phenomena at large. Ultimately, this then also gives rise to new proposals for experiments in the laboratory, as it allows one to move general features of the 'relativistic framework' from general relativity to entirely new new areas of physics. This allows one to experimentally look into analogies of currently unobservable phenomena of general relativity proper. The only requirement for this to work is the presence of a notion of an upper limit for propagation speeds in this new setting. Systems of such a kind abound in physics, as all hyperbolic wave equations fulfil this requirement.
