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?
Shouldn’t 7/10" actually be 7/20"?
What in the motherfuck are those numbers
What the fuck is wrong with your units
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.
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.

That Schwarzschild radius is larger than I expected. I was expecting sub-molecular.
