Malcolm Gladwell's miscellany of myths

The radius (the Compton wavelength) of a particle is inversely proportional to the particle's mass:

"The Compton wavelength, λ, of a particle is given by λ = h/mc, where h is the Planck constant, m is the particle's rest mass, and c is the speed of light." [Source]

That is why as the electron's mass decreases, its size increases. The size of the proton, on the contrary, decreases (because its mass increases). Eventually, the size of the electron (the basic localization plus the tail) expands to the size of the universe, while the radius of the proton contracts to the Schwartzchild radius corresponding to the proton mass:

"4.5 The ultimate fate of the Universe

In Section 3 we saw that at a time n = N (where n is the time in atomic time units, and N is the baryon number of the Universe), the evolution of the Omega Universe reaches a state at which the Planck length is equal to the Compton wavelength of the proton, and the Planck mass is equal to the proton mass. In other words, the scale factor of the Universe has evolved to the point where the radius of the proton exceeds the Schwartzchild radius corresponding to the proton mass. At this point the Universe effectively comes to an end as all protons simultaneously collapse into micro Black Holes." [Booth, Robin ♦ Machian General Relativity ♦ page 16]

The size of a Planckian black hole calculated by Craig Hogan is 10−16 m (see End of Locality).

The radius (the Compton wavelength) of a free proton (+R) is 2.10553 × 10−16 m [Hofstadter, R. ♦ Reviews of Modern Physics, volume 28, p. 213 (1956)]. [Source]

This means that the universe's protons are on the brink of a black-hole collapse.

Here is a quote from a recent Malcolm Gladwell interview:

"....Outliers is a lot like Blink and Tipping Point. They are all attempts to make us think about the world a little differently."
