Title text:
Frankly, given their extreme gravitational fields and general instability, even 12-inch globes should probably be banned.

There’s also the fact that people might not be able to use it if it’s too small.
4" is a respectable size, okay? It’s nothing to scoff at.
It’s all about your spin game anyways
subdued scoffing
Maybe its less about the size and more about the technique?
That Schwarzschild radius is larger than I expected. I was expecting sub-molecular.

Shouldn’t 7/10" actually be 7/20"?

What in the motherfuck are those numbers
What the fuck is wrong with your units

They’re literally called rational numbers

The same question is in the discussion section in ExplainXKCD, so I can confidently use the reply given there: No, 7/20" is the radius, but 7/10" is correct for the diameter.

Oh right, didn’t pay enough attention. But it was the first thing I saw in the morning.

Notice how the lines the 7/10" is attached to go from one side of the miniature globe to the other? This indicates that measurement is meant to be a diameter. Looking back at the paragraph before he talks about 0.35" being Earth’s Schwarzschild Radius. Radius is half of diameter so doubling that radius you get 0.7 or 7/10" across at which the Earth would become a black hole.
That’s what that mini diagram is showing.
