C'mon guys, help me out here. Is the speed of light a constant that could be used to derive an "absolute second in time" or something? I don't know how to properly describe what it is I want say in a fomulaic manner.
Is time believed to be a constant or is it merely a function of the perception of the observer? My understanding is that if Astronaut Poole was just outside of an event horizon and Astonaut Bowman was just inside the event horizon, their repsective perceptions of time would be drastically...
