@roundsquare I look at things too logically. Too concretely. To me, E=MC^2 is saying “Energy equals mass times the speed of light squared.” If you put that in kindergarten terms, to me, it’s like saying “2500=25*(10^2)”..... (10^2 representing the speed of light squared in this example) but that’s a literal answer and it doesn’t literally apply to that equation. It’s a concept, and, like Rarebear, when I dwell on it, and people educate me, I begin to understand it intuitively. But I lose that understanding pretty quickly due to Other Things Encroaching (Life, in other words.)
How about we discuss something simple like, “If you had a pole that was the speed of light long, and you wiggled one end of it, how long would it take for the wiggle to translate to the other end.” Yeah. Something simple. Like that. (sigh)
As for @Vortico… you said, “Or you could imagine a box with depth c, width c, and height m. The amount of water this box will hold represents the object’s energy.” Thank you for that. I’ve been thinking about it, but I’ll think about it some more because at this point all I can come up with is…..DO YOU KNOW HOW MUCH FREAKING WATER THAT WOULD BE??? .....
