If "the firmament" actually exists, it's likely a force field around out planet to either protect us and/or keep us from shitting up the galaxy.
Might explain why certain civilizations were seemingly so advanced in the past, capable of things we don't really know how to do today. Something catastrophic happened and we were cut off from the rest of the galactic community until we are ready to re-join? Like a space-age time-out kek.
I heard it while VP was speaking, FOX people seemed like they didn't expect it as well.
Go be a faggot somewhere else.
