> 3 x 10^35 blue whales That’s way more confusing. Most people have never seen a blue whale to scale, let alone can imagine how dense it is. Once you’re at 10^35, why not just increase the exponent and use humans, basketballs or soda cans. I would imagine that the best scale of measurement would be between 1/100 and 100x. If the Milky Way is about 1.9T solar masses, then this black hole is about 1.5% the mass of our galaxy. It’s still a pretty meaningless number, but at least I can look at a picture of the Milky Way and envision 1.5% collapsing into a single object much more easily than I can envision 10^35 of anything.
