It’s been a minute, but the universe is expanding and the speed of the expansion depends on the total gravity. When we calculate the amount of mass it would take to make that much gravity, it’s way more than what we actually see out in the universe. It’s really a cheeky way of saying our current model makes tons of good predictions so we trust that something is out there, but in reality we don’t know its nature and can’t detect or measure it directly.
