That’s what they say, anyway, at Wolfram Math: “The human body has a mass that, more or less, is halfway between the mass of the proton (~1.672×10 ² kg) and the mass of the Sun (~1.988×10³ kg). A value very close to the mass of an average human body is the geometric mean of those two values”

Please correct the indicated masses – they are obviously very far off.

Yes, the sun weighs a bit more than 2000 kg. 🙂

And that’s one might heavy proton, even if News means 10^(-2).

It’s about half way on the log scale.

And, ironically, the mass of the sun News gives is quite close to the mass of a proton car.

More interesting still, why is the size of a human egg, and human vision, halfway between Planck length and the size of the observable universe?

in the following video physicist Neil Turok states that we live in the middle, or at the geometric mean, between the largest scale in physics and the smallest scale in physics:

And here is a picture that gets his point across very clearly:

Whereas Dr. William Demski, in the following graph, gives a more precise figure of 8.8 x 10^26 M for the observable universe’s diameter, and 1.6 x 10^-35 for the Planck length which is the smallest length possible.

Dr. Dembski’s more precise interactive graph points out that the smallest scale visible to the human eye (as well as the size of a human egg) is at 10^-4 meters, which ‘just so happens’ to be directly in the exponential center, and/or geometric mean, of all possible sizes of our physical reality. This is very interesting for the limits to human vision (as well as the size of the human egg) could have, theoretically, been at very different positions rather than directly in the exponential middle and/or the geometric mean. Needless to say, this empirical finding directly challenges, if not directly refutes, the assumption of the Copernican Principle which holds that that there is nothing special about humanity:
