I have a question about singularities. Determining the density of a singularity involves the mathematically absurd and undefined function of dividing by zero.(adsbygoogle = window.adsbygoogle || []).push({});

What I don't get is this : How can a mathematically absurd entity exist in reality ?

Also, if you multiply the density of a singularity by its volume to get its mass, you get the mass of the singularity as 0. Is that not absurd ?

Ultimately, what I want to know is : How can a real object be defined in absurd and undefined mathematics? That seems to be a revokement of everything I've ever learnt.
