Distance: A 2024 re-examination

Distance, a concept that continues to be relevant and rather complex, is far from being obsolete despite its diminishing role in the age of virtual space. It represents spatial separation, a notion that was first quantified in Egypt some 5,000 years ago. The evolution of distance can be traced through five distinct phases: natural (absolute and relative distances), relational (time and cost distances, distance decay, friction of distance, and distanciation), technological (extensibility, accessibility, and speed), virtual (proximity, digital, cognitive, and metaphorical distances), and optional (optional and estimated distances). These historical phases have built upon each other, leading to our contemporary experience of all distance classes depending on specific separation cases. Modern humans may overcome any distance on earth, one way or another, unless prevented from doing so by political national sovereignties.
