If the speed of light were reduced to match the speed of sound at 331 m/s, there would be a noticeable delay in perceiving events, similar to how we see lightning before hearing thunder. This delay would not be significant for human observers at 330 m/s, but at much slower speeds like 3 m/s, moving objects could reach a person before their visual perception of them, complicating everyday experiences like crossing the street. The discussion also touches on how this change could affect our understanding of relativity, as light from distant stars would take much longer to reach us, making the information appear outdated. Overall, the implications of such a shift would fundamentally alter our perception of time and space. The conversation invites further exploration of these concepts in relation to real-world physics.
