What the article says around this equation
where the second equality for a Schwarzschild hole follows directly from Hawking’s temperature formula [ 7 ] and S = A/4 is the Bekenstein-Hawking entropy [ 6 ] . For a solar-mass hole, 1.2410^{-4}\, and S 177 , giving 3.5\, — an exact evaluation of the stated formulas, illustrative of the scrambling scale and not a claim about any particular measured hole.
