Space-time may be emergent from something more fundamental, though
(space-time foam?). It is unknown whether space-time is infinite, but
if Guth's theory of eternal inflation is correct, then in some sense
the multiversal structure of space-time is infinite in extent, but may
be causally inaccessible to beings within a given branch of it. An
ontological question regarding the nature of creativity presents
itself: is "newness" just a rehashing of the "old" or is it truly new?
This question relates to creativity of all kinds: artistic,
mathematical, ontological and is of great metaphysical importance.

Chaitin has pursued investigations into the evolutionary development
of human creativity, particularly the mathematical type, using his
theory of algorithmic information which you may find interesting.

Thank you for sharing this excellent and informative video.
