Hi! I have a question on Lawrence Krauss' perspective on nothingness or nothing: "Krauss continues implicitly to abide by the adage in its literal sense by denying that sheer nothingness can give rise to anything. He does so by positing a quantum or spatial something of seething energy that is not yet the multiple somethings of the universe but contains all the potentiality from which these innumerable somethings can be made actual." Does Krauss suggest that the "quantum vaccum" is the nothingness from which something arises? This nothingness does not mean absolute nothing (what the Greeks called "ouk on") but relative non-being or pure potentiality (me on) from which something can emerge or "stand out" (ek-sistere). It seems that there are parallels to Aristotle's prime matter and potentiality/actuality distinction. Some physicists have said that pure energy in beginning of the universe have similarities to what Aristotle called prime matter. Whatever it means these views seem to suggest that everything that exists in our world emerges from some kind of underlying substratum of potentiality where all possible outcomes dwell - a state of readyness to generate something. Does this have some merit in the physics community? Kind regards Alex
