Yes, but a two-dimensional plane in and of itself does not contain anything. However, if what you're saying is that everything exists within this two-dimensional plane, then it suggests that we are living in some sort of illusion and, that in fact somebody has pulled the wool over our eyes. Which, of course has been my contention all along. But then again, it might make more sense if we said everything existed
relative to the observer. Isn't this in fact something that Einstein said? Which of course makes even more sense when I say we are
not to discount the observer. Not within the parameters of time and space anyway.
