Date: May 3, 2026; Source: Foundational Questions Institute, FQXi Summary: Physicists are rethinking one of quantum mechanics' biggest puzzles: how fuzzy possibilities become definite reality. New research suggests that spontaneous "collapse" processes--possibly linked to gravity--could subtly blur time itself. This wouldn't affect clocks we use today, but it reveals a hidden limit to how precise time can ever be. The findings open a new path toward uniting quantum physics with gravity.
