It's just a flat. So if you put 20 MJ into the Conduit system and the only thing hooked up is a Redstone Energy Cell, that cell will have 19 MJ regardless of if it's 1 block away or Graham's Number blocks away. Just ignore the fact that Minecraft worlds are finite and you can't have Graham's Number blocks between two points. And the fact that the theoretical limit for the RAM of a supercomputer that takes up the entire observable universe, even with absurdly futuristic technology, is an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to an insignificant speck compared to Graham's Number.
Notice that I left out a number of "compared to an insignificant speck's" mind-numbingly greater than 10 to the number of hypercubic planck lengths in the history of the observable Universe. And even with that said, I've still understated the size of Graham's Number more severely than a billion Withers would pwn a player with no armour.
