Theories of Everything with Curt Jaimungal

NOTE

Causality and the Nature of Wave Signals

When the group velocity of a wave signal exceeds the speed of light, it challenges traditional concepts of causality and can create scenarios where signals appear to travel backward in time from certain frames of reference. This phenomenon is based on an idealized assumption of a wave existing indefinitely without a beginning or end, which complicates the understanding of frequency and the implications of such signals on our perception of time and causality. Acknowledging the complexity of these waves reveals the nuanced nature of how we interpret velocity and causation within the framework of physics.
