Thus spake Oh No
Thus spake " Parenthetically, the revised Schwarschild radius for the proton is about 0.8 x 10^-13 cm, which is about equal to the charge radius of the proton and the revised Planck length. I should just like to add that the Schwarzschild radius of the proton is not something which appears in standard physical models, the reason being that a classical massive point particle is not a consistent idea in general relativity. In fact a proton must be treated quantum mechanically, and we do not have an accepted theory on that, but if the Schwarzschild radius of the proton were considered then it would have a magnitude given by 2Gm/c^3 =3D 8.28 x 10 e^-63 m Planck length also has a formal definition l_p =3D sqrt(hbar*G/c^3) =3D 1.61605e-35 =B1 1.0e-39 m Neither of these figures is open to revision beyond that allowed by experimental margins of error. If you are defining other quantities, you should give them other names. With apologies, I copy pasted those figures from another source. The equations looked all right when I posted, but obviously they did not contain pure ASCII and they appear to have been corrupted by one of the gateways used by s.a.r. = has come out as =3D and +- has come out as =B1. They should read Schwarzschild radius of the proton 2Gm/c^3 = 8.28 x 10 e^-63 m Planck length l_p = sqrt(hbar*G/c^3) = 1.61605e-35 +- 1.0e-39 m Regards -- Charles Francis substitute charles for NotI to email |
