Why is it necessarily the case that "stars would compress into this material rather than into black holes"? For example, why can't it be the case that there are two kinds of matter, one that can be used to build infinitely strong wire, and one that can't, with stars being made of the latter? Or why can't it be the case that the crushing process doesn't take matter through the infinitely strong configuration on the way to black hole configuration?

> Why is it necessarily the case that "stars would compress into this material rather than into black holes"? There's a good argument to be made that this isn't necessarily the case. I was thinking that all particles are interchangeable at sufficiently high temperatures (i.e. they can switch from one particle to another so long as energy is conserved). I overlooked the fact that stars don't get hot enough. > Or why can't it be the case that the crushing process doesn't take matter through the infinitely strong configuration on the way to black hole configuration? If the "infinitely strong" configuration got crushed into a black hole, it wasn't infinitely strong. > For example, why can't it be the case that there are two kinds of matter, one that can be used to build infinitely strong wire, and one that can't, with stars being made of the latter? How would the infinitely strong wire be held together? Electromagnetic force? Strong force? Weak force? Those forces (which are the only ones we know about apart from gravity) travel at c. If part of the wire is in, while part is out, we will necessarily break the bonds holding the material together if we attempt to pull the wire clear. If nothing else, this breaking will occur because those bonds rely on force carriers traveling at c, and so somewhere along the wire those force carriers will not see the items they are supposed to bind together. Let us say we hold the wire so that a portion of it is past the event horizon. The bit of the wire at the event horizon, if held stationary, is traveling at c because light is also stationary there. Whatever bond existed at that point is no more; the force carriers can't make it to the particles they're supposed to bind together.
