Sense all things have an equal and opposite, I tried to imagine what might be the counter-part to “E=mC^2”. So I took the latest #'s from Wikapedia on the percentages of the universe

matter=4.9%

Dark Energy=68.3%

Dark Matter=26.8%

I then took the equation, and simply replaced the "E" with "m" (sense

matter converts to energy). I then took the "m" and replaced it with Dark Energy

(sense energy converts to matter). Lastly I took "C^2" and replaced it with

Dark Matter^2.

And Indeed : matter=DE(DM^2) = .049=.268(.683^2)

Can anyone explain why this is?
