A space for speculative ideas, thought experiments, and unproven possibilities. This section is for exploring “what if?” questions at the edges of science — including ideas that may be incomplete, incorrect, or ultimately impossible. Posts here are not claims of fact, but starting points for discussion, reasoning, and evidence-based critique.

In-depth, long-form essays exploring scientific ideas, uncertainty, and understanding. This space is for slower thinking — where a single idea is developed carefully rather than discussed quickly. Essays here are typically longer than standard threads and are written to be read thoughtfully, often offline. If you’re looking for something to sit with, reflect on, or print and return to, you’re in the right place.
