Can someone help me fix the Wikipedia page on the black hole information paradox (https://en.wikipedia.org/wiki/Black_hole_information_paradox)? It says

> the black hole radiates mass at a rate given by dM/dt = -aT⁴ where a is constant related to fundamental constants, including the Stefan–Boltzmann constant and certain properties of the black hole spacetime called its greybody factors.

The next paragraph says that M is inversely proportional to T and that the black hole evaporates in time proportional to M³. But this isn't consistent because solving dM/dt = -a/M⁴ gives an evaporation time proportional to M⁵.

I think it's the first formula that's wrong and it should be dM/dt = -aT². But I don't know quite enough to feel confident making an edit. Is there someone out there who knows what the fix should be?

The long‑term tracking of star S2 orbiting Sagittarius A* continues to be one of the most compelling confirmations of General Relativity. Over 27 years of observations show a clear Schwarzschild precession: the orbit doesn’t close but slowly rotates due to the intense curvature of spacetime near the supermassive black hole.
A beautiful example of how precision astronomy can test fundamental physics.
