Talk:3086: Globe Safety
Hello! First time i got to a comic first --172.69.176.76 06:17, 8 May 2025 (UTC) 104.23.175.202 (talk) (please sign your comments with ~~~~)

I believe he indicates that a globe is made by making a copy of the Earth, and then compressing it until it fits on a desktop. Hence having the same mass and thus the same Schwarzschild radius as Earth. I have changed the explanation a bit because of this observation.--Kynde (talk) 05:42, 8 May 2025 (UTC)
Gotta wonder what kind of a desk could support a desktop globe that weighs as much as the Earth --StumbleRunner
- [...] desk? Convince me that such a globe wouldn't plunge straight through the Earth's crust and into the mantle. I sense a marketing problem. 172.71.147.69 07:07, 8 May 2025 (UTC)
Radius. Is there a typo in the comic where 7/10" should be 7/20", i.e., 0.35" as later written? Or would a 7/10" Earth collapse into a black hole nonetheless?172.71.154.129 06:40, 8 May 2025 (UTC)
- Nope… the Schwarzchild radius is 0.35", which is indeed 7/20", but the measurement shown on the globe is the diameter, not the radius, so 7/10" is correct. 172.71.178.143 06:49, 8 May 2025 (UTC)
Isn't there also a jab at the weird way USsians use power-of-two fractions for inch measurements? I've never seen something like 7/10" before, it would be approximated as 11/16".172.71.95.69 09:18, 8 May 2025 (UTC)
- It isn't a weird USian thing - it's just the historical way that inches (being a non-metric unit) were divided. The same way that an inch is a 1/12 division of a foot, which is a 1/3 division of a yard, etc. 141.101.98.83 10:23, 8 May 2025 (UTC)
I think we have a bigger problem: there are millions of globes on Earth! I haven't done the calculations, but that might be enough to turn Earth into a black hole already; if not, I expect at least it would turn it into a star. --104.23.190.34 11:44, 8 May 2025 (UTC)
BTW. what would be a 12-inch object with a mass of Earth? Neutron star? Neutron planet? Neutron meteoroid? -- 12:46, 8 May 2025 (UTC)
- Crunching the numbers (thanks to Copilot.microsoft.com):
- A sphere with a 30 cm radius has a volume of about 1.13×10-2 m³.
- Compressing Earth's mass into that volume gives a density of roughly 5.3×1028 g/cm³.
- That is way way denser than a neutron star. It's doubtful that such a sphere would remain at that density; it would likely explode immediately, or if prevented from doing so, continue to shrink down past 9mm and become a black hole. 172.70.110.59 (talk) 13:26, 8 May 2025 (UTC) (please sign your comments with ~~~~)
