"The 9th Portal"

The 9th Portal - this is a stretch, but I was thinking that if there are pyramids scattered all over the planet - maybe there are portals scattered all over the galaxy 🐱‍🚀, remnants of some long dead super-civilization, now all but forgotten. A stark reminder that even civilizations far older, more advanced, and greater than our own eventually, inevitably, cease to exist....so can we make this thing work?
