> The only thing "dark matter" and "dark energy" have going for them is unfalsifiability for our type 0.5 civilization. I don't think that's fair at all. Neither phenomenon is unfalsifiable. By definition, dark matter an unknown gravitational effect. It's not fundamentally unfalsifiable, we just don't know what's causing it. The assumption is difficult-to-detect matter seems most likely because theories like MOND which suggest that "maybe gravity works differently from how we thought" are being investigated actively and just don't seem very likely so far.
