> If everything has a Schwarzchild radius determined by its mass It doesn't, not in the sense you mean. You can calculate a Schwarzschild radius for any mass, but that radius only means something physically for an actual black hole. You can use the calculated radius to estimate how hard it would be to turn some ordinary object into a black hole; that's what the article does by comparing the Schwarzschild radius for various masses or energies to the actual radius within which we can compress them by processes we can currently control (and of course the latter radius is very, very much larger than the Schwarzschild radius for those masses or energies, which means we have no feasible way of turning any of those objects into black holes). But that in no way means that those ordinary objects have some actual, physical Schwarzschild radius that acts like the horizon of a black hole. They don't.
