Doctor Who is a classic character of science fiction. He travels through space and time in a sentient machine called the TARDIS. The first thing that most people remark when stepping into the machine is “It’s bigger on the inside!” This, I think, is the situation we find ourselves in with time.
As a hybrid consequence of our biological inheritance and the implicit, linear teleologies of language, we are all quite naturally prone to think in terms of time as linear. Certainly, we are able to measure and quantify various metrics yet the applied (engineering) utility of various technical vocabularies can be misleading.
The accelerating, combinatorial hyper-inflation of material systems is a coefficient of entropy. This is a function of referential self-inflection. Consider Cantor’s diagonal method as a powerful intuition of an indefinitely-extensible self-referential systems ontology.
Extension in time is not additive, it is (logically) subtractive and this – in essence – is the cognitive (as epistemological) hurdle we have all and always faced when considering temporality. System entropy is this hyper-inflected introspection of a maximally interconnected system that reduces connections logically, even as it adds them materially.
