New Insights into Time from Quantum Physics

A new paper titled "A theory of time based on wavefunction collapse" by Sung-Sik Lee proposes a novel perspective on the nature of time in the context of quantum physics. The paper suggests that moments of time emerge through the failure of temporal diffeomorphism as a gauge symmetry. It argues that the passage of time is a continuous process where an instantaneous state collapses toward a gauge-invariant state.

The author demonstrates the unitarity and directedness of time evolution using a minisuperspace model of cosmology. This approach could have implications for understanding the fundamental nature of time and its relationship with quantum mechanics.

The findings may influence future research in both theoretical physics and cosmology, potentially leading to new insights into how time is perceived in quantum systems. The paper is available for further reading on arXiv: arXiv:2408.11905.
