Quantum collapse models suggest fundamental uncertainty in time, study finds

The short version

• Physicists analyzed alternatives to standard quantum mechanics called collapse models to evaluate their relationship with gravity and time.[ScienceDaily]
• The theoretical framework establishes a link between Continuous Spontaneous Localization and spacetime gravitational fluctuations.[ScienceDaily]
• Researchers emphasize that this predicted temporal uncertainty is vastly smaller than current measurement limits, leaving modern timekeeping unaffected.[ScienceDaily]

Key facts

• The research was published in the journal Physical Review Research.[ScienceDaily]
• Researchers established a quantitative connection between Continuous Spontaneous Localization and gravitational fluctuations in spacetime.[ScienceDaily]
• The study suggests that quantum collapse models could impose fundamental limits on the ultimate precision of clocks.[ScienceDaily]
• Co-author Catalina Curceanu noted that the predicted uncertainty is orders of magnitude below current detection capabilities.[ScienceDaily]
