Physicists Find Fundamental Clock Limit in 2 Quantum Collapse Models

2 articles · Updated · ScienceDaily · Sep 11

Summary

  • An international team calculated that time may carry a tiny intrinsic uncertainty, implying an ultimate ceiling on how precisely any clock can measure it.
  • The result comes from analyzing 2 quantum collapse models—Diósi-Penrose and Continuous Spontaneous Localization—and linking spontaneous wavefunction collapse to gravity-driven spacetime fluctuations.
  • The predicted effect is many orders of magnitude below the reach of today’s best atomic clocks, leaving current and foreseeable timekeeping technology unaffected.
  • Published in Physical Review Research, the work offers a potential experimental route to distinguish collapse models from standard quantum mechanics and a possible clue toward unifying quantum theory with gravity.

Insights

If gravity triggers quantum collapse, will tomorrow's ultra-precise nuclear clocks reveal that time is built on random fluctuations?
If time itself has a fundamental limit of precision, what happens to reality when we try to measure beyond it?
