The discussion revolves around the nature of axioms in physics, the relationship between experimental evidence and theoretical constructs, and the validity of physical theories. Participants explore whether physics has foundational axioms similar to mathematics, how key principles like F=ma and the constancy of light were established, and the implications of scientific theories being open to revision based on new data.
Participants do not reach a consensus on whether physics has axioms similar to mathematics. There are multiple competing views regarding the nature of physical laws, the role of experiments in establishing theories, and the definitions of axioms and postulates.
Participants express uncertainty about the definitions and implications of axioms and postulates, indicating that these terms may vary in meaning depending on context. The discussion reflects the complexity of establishing foundational principles in physics and the ongoing evolution of scientific understanding.
No, that's not true. Simultaneous events that occur in the same place remain simultaneous with respect to all reference frames, regardless of whether they are inertial or not or whether they rotate or not.jbriggs444 said:Since the rest frame of Westminster Abbey is rotating, that leaves some remaining troubles with simultaneity.
We are not talking about events that occur in the same place. We are talking about an event occurring at Westminster Abbey (e.g. coronation) and a separate event occurring in Australia (the time there when the coronation is deemed to have taken place). Those two events are space-like separated.Jaime Rudas said:No, that's not true.
