The astronomical mass of a black hole is completely undefined. Its no way out to assume its mass. One of the factor is its extremely huge gravitational/magnetic pull. Any matter (even light) cant escape this freakin object. Lol

But, its a very interesting topic. It made me think outside the box. Im basing on your statements though I have a basic knowledge about black holes. Thanks @sammosk Buddy ! :) Resteeming this awesome article.
