The discussion explores whether stars in space interact through wave-cancellation, comparing it to water waves created by throwing rocks into a pool. Participants clarify that while wave interference can occur, the likelihood of two stars emitting identical frequencies for destructive interference is extremely low and would only be a localized phenomenon. Light behaves differently from water waves, as it does not require a medium and is typically incoherent, meaning it does not exhibit the same interference patterns. The consensus is that while wave interactions exist, they are not significant in the context of star interactions. Overall, the idea of stars affecting each other through wave-cancellation is deemed unlikely and not impactful.
