I'm not the brightest bulb in the pack so please bear with me. I have a problem with the whole E=mc2 equation. The fact that time is included with the measurement is beyond me. Time is a measurement itself so how can it be considered a physical property? Time is a measurement of a cycle or distance, but since our minds are capable of remembering the past, sensing the present and predicting(not like a psychic) the future we seem to be stuck referring to it as if it where a physical thing. I guess what I'm saying is I really don't understand how the frizzy haired guy came up with it? Besides, the whole one clock showing a different time than another when in motion would seem to be physical property of the increase in mass as it approaches the speed of light not time dialation.What am I missing here?
