Phase-continuous comparison of three all-optical time scales over 20 days

This paper demonstrates the creation and 20-day continuous operation of three parallel all-optical time scales using optical flywheels and an optical frequency standard, which achieve superior short-term stability and sub-100 picosecond total time difference compared to traditional maser-based systems, paving the way for the future of optical timekeeping.

The Informational Universe: Physical Law as Maximum Informational Complexity

This paper proposes the Principle of Maximum Informational Complexity (PMIC), a variational framework asserting that physical reality is the unique mathematical structure maximizing the net information score of observer-state repertoire minus law-description cost, thereby deriving fundamental symmetries and predicting specific fine-tuned constants like the cosmological constant and fine-structure constant as necessary peaks in an information landscape rather than arbitrary anthropic coincidences.
