This is the thought experiment, the attempt to define something out of The Box:
1: Everything exists.
2: Endless is a concept and an attribute.
3: To be Endless is to have no end.
4: Instantiating existence implies the existence of an end towards that existence.
5: Nothing which existence is instantiated can be endless.
6: Not everything is instantiated to exist, but by necessity.
7: The Box is not instantiated and exists by necessity.
8: The Box can be endless.
9: The Box is not endless.
10: A Endless Box is greater than The Box.
11: The Endless Box exists by necessity due to (1).
12: The Endless Box contains The Box. It has no end.
