There are fewer that are very smart and only a very few that are exceptionally smart - and some of these exceptionally smart state that they do not understand time and/or space. Then there are those that are so dumb that they think they are smart - and do understand time. D.Y.K.

Einstein showed numbers. Time being change by digits, the more direct question is what is change? I think future generations, if coping drug free, are going to put numbers in a more realistic perspective. We have gone ga-ga over them since the late 1800's and have assumed way too much with them. Anyway imo now, the property of change is potential, it's state is non- duration. Space is an arbitrary assignment relative to specific objects, objects big and small that are still being discovered with each new scope.
