All this talk of time not existing makes me nervous. Is there any way to test this idea or is it purely conceptual? The point I was trying to make (poorly) is that if the idea of time as a dimension is helpful (and it certainly is with the concept of velocity shared in four dimensions) and practical (GPS wouldn't work without it), why bother with making such a claim as "time doesn't exist". Does it make more sense that way in situations I haven't heard of? Is there a thought experiment we can do that might distinguish between no-time and time?
