The symbol for radius is usually a lowercase “r”. The symbol for the SI unit of metre (or meter) is “m”, not “M”. [“M” is reserved as the unit prefix for “mega”, from greek «μέγας» /megas/ „great“, meaning one million times the unit.] The SI unit prefix “k” (for “kilo”, from Greek «χίλιοι» /khílioi/ „a thousand“) means 1000 times the unit: 1 km = 1000 m. So 1.3 × 10¹⁰ m = 1.3 × 10⁷ km which is *much less* than 1 AU ≈ 150'000'000 km = 150 × 10⁸ km = 1.5 × 10¹⁰ km. (1 AU is the average distance Terra–Sol.) > (in the section on Schwarzchild radii (Karl) _Schwarzschild_ > - which is suspect is out of date) It is not. The Schwarzschild radius of a non-rotating, uncharged (Schwarzschild) black hole (BH) is rₛ = 2 G M∕c², where G is Newton’s gravitational constant, and M is the mass of the black hole. A mass of M = 4.1 × 10⁶ M☉ ≈ 8.153 × 10³⁶ kg, where the mass of Sol (or solar masses) is M☉ ≈ 1.988435 × 10³⁰ kg, corresponds to a Schwarzschild radius of rₛ ≈ 1.211 × 10¹⁰ m = 1.211 × 10⁷ km ≈ 0.08094 AU The is very close to the aforementioned 1.3 × 10¹⁰ m. See also: <http://www.wolframalpha.com/input/?i=Schwarzschild+radius&dataset=> > (although the page on Sgr A itself says 4.1M sun and about 45AU) You are confusing the radius of the region surrounding the assumed black hole with the Schwarzschild radius of the black hole, whereas the former is much larger. Note that for such a BH, the Schwarzschild radius is the radius beyond which we can have *no* information instead (as it *is* the radius of the *event horizon*). > Star S14 must be getting awfully close to grazing the event horizon. That is possible, but not based on your argument, but based on the diagram. For a Schwarzschild BH, the outer event horizon is the surface of a sphere that has the Schwarzschild radius as its radius. 45 AU, the radius of the space in which S14 is described to be orbiting, is not anywhere near 0.08 AU. -- PointedEars Twitter: @PointedEars2 Please do not cc me. / Bitte keine Kopien per E-Mail.
