Re: Science-based what-if questions

If we step away from infinity, the point is that at any given scale, all extensive properties will be scaled similarly, so there will be no qualitative difference. In such a universe, there would be no particular reason the Earth should be 12,700 km in diameter rather than 12,000,000 km or 12 km or ...

Re: Decitauths

I think the idea was that 12 is demonstrably superior to 10 because it has more factors. Of course, "decitauths" rely on the calculation (2π)2*10 = τ2*10 ≈ 62*10 = 360, so it's sort of the worst of both worlds.
