Overview
- An international team supported by the Foundational Questions Institute reports that certain collapse models imply a minuscule intrinsic uncertainty in time.
- The study examines the Diósi–Penrose model and Continuous Spontaneous Localization, deriving a first quantitative connection between CSL and gravitational spacetime fluctuations.
- The predicted effect imposes a fundamental limit on clock precision, though the uncertainty is extraordinarily small.
- Authors stress that the effect lies many orders of magnitude below current sensitivity, leaving atomic clocks and everyday timekeeping unaffected.
- Published in Physical Review Research in November 2025, the work motivates future tests that could probe links between quantum mechanics, gravity, and the nature of time.
