>>13496473the average column density of space can be measured directly and the results of that measurement show that the matter density of space is roughly 0.5 - 10 election masses per cubic meter, depending on how much dark matter you believe in.
the average temperature of space has also been measured
i really hope that one day brainlets will get over their transparently incorrect assumption that everything in the universe is a perfect vacuum at 0ºK because that temperature and density combination exists nowhere in this universe except maybe in a lab somewhere.
