Tungsten Blackhole Model

$39.99

 If you compress any amount of mass, it becomes denser. If you compress it enough, it will become so dense that light can no longer escape it—this size is the object’s Schwarzschild radius. An object that is compressed smaller than this radius is a black hole.   This tungsten sphere has been engineered to have exactly the same radius as the Schwarzschild radius of Earth. If you compressed all of the mass of Earth into the volume of this tiny sphere, it would be so incredibly dense that you would not even be able to see it.   This sphere is a great aid for comprehending the scale of black holes and their extreme density. Made of tungsten, one of the densest elements in the universe, to help illustrate the high density of such an object. 

 Radius: 8.87 mm Weight: 53.34 g Density: 18.5 g/cc
