Part 2/11:

Starting with a descent into the realm of two dimensions, we encounter flat lifeforms that inhabit a world consisting solely of length and width, devoid of depth. In this astonishing hypothetical scenario, these beings can only perceive the world through thin cross-sections, much like experiencing an MRI scan.

Imagine putting a three-dimensional object into this flat world — the inhabitants would view it as a shape-shifter, watching as parts of our body seemingly materialize and vanish. Yet, could life truly thrive in this dimension? Computer simulations enable this exploration, such as the ALIEN program, which allows users to construct simple two-dimensional ecosystems. Here, virtual cells demonstrate the potential for self-replication and adaptation.
