| | | | | [AI summary] The text discusses the implications of quantum mechanics and the concept of expected energy in quantum systems. It highlights the difference between the average energy of a quantum state and the energy of the system post-measurement, emphasizing that the former is a statistical average while the latter is determined by the measurement outcome. The discussion also touches on the broader context of quantum theory, including the role of measurement and the probabilistic nature of quantum states. Additionally, it references the importance of energy in physical processes and the connection to classical thermodynamics, suggesting that while quantum mechanics provides a framework for understanding energy at a fundamental level, classical concepts still... | |

| | | | | Merging quantum mechanics and gravity is a famously hard physics problem. Explaining why merging quantum mechanics and gravity is hard is, in turn, a very hard science communication problem. The more popular descriptions tend to lead to misunderstandings, and I've posted many times over the years to chip away at those misunderstandings. Merging quantum mechanics... | |
