The overwhelming scientific consensus, reinforced through decades of satellite imagery, space missions, and physics demonstrations widely depicted in documentaries and educational media, drives the 97.5% implied probability against a flat Earth. Trader sentiment reflects this cultural dominance, where mainstream narratives from NASA footage to globe-spanning films and viral science explainers have cemented the spherical model as settled fact, with minimal recent momentum for contrarian views beyond niche online communities. While realistic upset scenarios remain remote given the absence of credible new evidence or paradigm-shifting announcements, any hypothetical breakthrough in alternative cosmology would need to upend established visual records and global navigation systems to shift odds meaningfully before resolution.
