use coastline paradox as into to scale

introduce plank length on smallest scales

the largest distance is the diameter of the observable universe, just because observable universe is a hard limit doesnt mean there is absolutely no universe beyond it, just means that theres a limit to what we can ever observe.

the plank length is a hard limit in measurement which acts as the smallest meaningful distance of measurement

introduce math euclidean space and explain how measurement, scale carry over but are more limitless due to being pure abstractions.
