How unknowable it still is- the combination of known unknowns and the unknown unknowns.

The stuff of matter and energy is only 5% of our universe. And we know only a tiny fraction of that and barely understand the small fraction of that tiny bit.

The rest is 25% dark matter and 70% dark energy.

We know what dark matter kinda is. We don’t know anything about dark energy.

And we’re just whirring around a giant blue marble in all of it.
