The standard spiel is that ordinary stuff is 5% of the everything in the universe, dark matter about 25% and the rest – about 70% – is something called dark energy. Thereabouts. That’s on a “mass–energy equivalence basis” whatever that is.

Stuff, at least we can see it, although it goes very weird at the micro quantum physics level, where particles can be in two places at once, or in two different states at once, but if two particles are bonded, then change one and the other changes automatically and instantaneously even though kilometres apart in what Einstein called “spooky action at a distance”.
