      Set v = c to obtain Schwarzchild radius. https://en.wikipedia.org/wiki/Schwarzschild_radius …

      It’s a misleading coincidence that the Schwarzchild radius is where the classical escape velocity equals c, and this is often misexplained when introducing the concept of black holes

      Disagree. 1) Dimensional analysis demands this from, so at most GR could give a for-factor. 2) More deeply, Newton gravity doesn’t break down at event horizon, only far inside horizon.

      Dimensional analysis doesn’t get the 1/2 in 1/2gt^2, for example .. and again applying Newton’s law to light is completely unfounded in the context of Newtonian dynamics

      To everyone who thinks this isn’t misleading: applying naïve Newtonian physics to light being bent by gravity gives a factor of 2 discrepancy with the predictions of GR, even in “weak” limits. Newtonian physics is *not* valid to describe how light behaves in a gravitational field
