Even at double the previous estimate the thing that always floors me about the age of the universe is that it's a number that's approachable by human minds at all.

it could have been anything, trillions upon trillions of years, or subject to some nonlinear behavior that made it impossible to estimate at all in terms of current parameterizations of time.

And yet here it is a number we can almost see to the end of,conceptually, at the fringes of human scale reckoning.

Somewhat loosely related is the equally arbitrary-seeming and surprisingly small number of chemical elements, vs, say the uncountable number of living species.
