Just think of it as 'the other' Holy Grail'; not Time Travel, where we transport matter through time as well as space at a rate to paradox known cause and effect, no... the 'other' Holy Grail... Welcome to this thread, a thread that'll explore what sciences would be needed to turn waste / byproduct into energy, and anything else to a point of endless supply of anything and maybe anyone. Naturally; it will end Capitalism. Fore, if we're able to sustain ourselves on what we put out, and turn waste into resource, well, game over for Capitalism. In this thread, I wish to look at the economical impact on the ultimate Socialist and Science win. Science and The Replicator. What branches of Science would we need? Quantum mechanics and physics to move the atoms to change shape/and structure perhaps?
