should of clarified: (i obviously know you can change matter at the atomic level) if that is what you were referring to, i dont see how that precludes anything. i was asking you in regard to matter changing into something not "recognizable", as in something unknown to the periodic table. if you meant the latter than the question remains. if you meant the former, again i dont see how that precludes anything.
(my overall point in why i believe this is possible is because: are the grains of sand really that numberable? or the stars in the sky? or atoms? to us they are, but does that mean they really are?) that is why i believe this is possible. once infinity is realized, is anything numerable? if matter cannot be created nor destroyed. "although it may be rearranged in space and changed into different types of particles; and that for any chemical process in a closed system, the mass of the reactants must equal the mass of the products." -einstein in quotes...then why would we not be immortal? if a candy bar is immortal, shouldn't we be also? we are more complex than a candy bar but so what? we have infinity for our molecules to reform over and over. when they click into the right configuration, you got consciousness, when they dont, you have nothing. then they are broken down and re-arranged again. and again, and again and again.
