I know you're correct regarding the Hubble Volume, however, as the total universe is not the hubble bubble, and we may never get info beyond what we can detect, via the limitation of lightspeed, I still ponder if we might devise some manner of detection? Do go on other topics, because thumbs up or down on Godel, this'll take a while....

So you could make a Time Machine if Gödel's solution to Einstein's field equations was relevant for our universe, but it's not because the universe we live in doesn't spin.
