Scott Douglas Jacobsen: Could you use entropy in informational cosmology as something akin to a universal clock? Rick Rosner: You can. In Big Bang cosmology, entropy can be interpreted as a clock. However, both Big Bang cosmology and the laws of thermodynamics may fundamentally misunderstand how entropy and thermodynamics behave on tiny scales and over …

Scott Douglas Jacobsen: Why do you think the universe might last for trillions of years? And if it does last that long, what would that imply for the net informational history of the universe? Rick Rosner: It's likely far beyond just trillions of years. Depending on what we mean—whether it's heat death, proton decay, black …

Scott Douglas Jacobsen: How does IC reconcile the view of the universe as an information-processing system with the probabilistic nature of quantum mechanics, particularly the role of information in quantum states and the measurement process? Rick Rosner: I can answer the first part of that. We’ve talked about it before—Einstein hated the idea that the …

Rick Rosner: In physics, there are many conservation laws or principles that are generally supported by experimental evidence. For example, energy is conserved, and momentum is conserved. The conservation of information is a more complex and debated topic, particularly in quantum mechanics and cosmology. While there are arguments that information is conserved in quantum mechanical …
