Nemosine Singularity Fountain Pens

A space-time singularity occurs when mass is compressed into an incredibly small space wherein both gravity and density become, in theory, infinitely large. The Schwarzschild radius of a body is the radius to which the matter must be compressed for the escape velocity to become equal to the speed of light... effectively creating a black hole. The Schwarzschild radius of the earth is approximately 8.7 millimeters.   

Every Nemosine Singularity pen box is marked with the Schwarzschild radius equation, where:
R = Schwarzschild radius, G = gravitational constant, M = mass, c = speed of light
