What does "Nothing" mean to you?

You already understand that "nothing" is an absolute falsity. There is no such thing as "nothing." When the universe was created, it came into being from gluons and quarks of antimatter. Zero is probably the most important element of mathmatics. When anybody says there is nothing, they are admitting that there is something. The human mind cannot accept "nothing" because there is always something to occupy it, even at death.
