To be clear, I'm not suggesting it is perfectly understood by anyone, let alone myself. But it is not a complete mystery.

I don't think anyone understands it really -
it's outside our normal 3 dimensional world of senses.
Space time - adding that extra dimension of time -
is hard enough to understand - it's bizarre but real -
yet alone a universe expanding into itself.
