She: It's not that big.
He: I think we can agree everything below the average between a Planck length and the size of the observable universe is objectively small, and everything above is objectively large. Using the geometric mean, that average is about 0.12 mm. Therefore my penis is actually large.
She: I shouldn't have married a physicist.
Average? So around half the size of the observable universe?
They specified the geometric mean.
The arithmetic mean (what you're thinking of) of 1 and 100 is 50.5.
The geometric mean of 1 and 100 is 10. It gives a sense of the average magnitude.
They edited the comment, previously it did not mention geometric mean.
