You know, that's a really good point, and I think that's already how most of us think of orders of magnitude in such extremes. I never would have articulated that way however, very cool. Still, I have doubts that while I agree, you'd win over the huge numbers of people who want what they think is a "real-world" comparison. I find it odd that somehow a nuclear detonation qualifies, but hey, I guess it's all about preconceptions (not yours).It's actually better to think in terms of things that will give you numbers between 1 and 100. I can imagine a 100 trees or seashells, and I can imagine the difference between 1, 10, 100, or 1000 of something.
I can't really imagine 10^28 of something. However, I can imagine 28.
It helps to think of two numbers. For supernova, the numbers are 1 and 51, both of which I can visualize since they are less than 100.
