Matt: Is void a vacuum of space, David, or is it a solid?-No thing is no thing. Beyond our universe is nothing. Our universe has its particular and peculiar space with quantum potentiality. Our universe is all that is. Nothing is not something. A void is a void is a void. (Gertrude Stein)It is not a space vacuum nor is it solid. Complete nothingness. If I could lay my eyes on the philosophers who agree with me I would quote for you, but I don't know where to look at the moment. The universe expands, against resistence or against nothingness?
