sci-fi plot idea: with "folding space" being a common trope for FTL in fiction, there's got to be at least one elder/precursor/old species that got bored and uses their phenomenal power to make galaxy origami
"oh, that galaxy? yeah, we folded that into a duck, it's pretty cool"
wait, this sounds like something Q would do
which would also explain all the spacial and temporal anomalies they run into all the time in star trek...
new theory; Q got bored, did a load of folding, and now if you look at the alpha quadrant from the 27th dimension it's a little origami Jean-Luc Picard
