More juicy awesomeness from Randall "XKCD" Munroe's "What If?" series! This week, Randy looks at what you'd get if you marshalled a mole (6.022×10^23) of moles (small burrowing rodents). First cut: you don't want to do it on Earth, as they'd have half the mass of the moon ("This smothering ocean of high-pressure meat would wipe out most life on the planet, which could—to reddit’s horror—threaten the integrity of the DNS system.") So, you stick 'em in space, where they'd form a meaty, cooling, rotting planetoid:
The mole planet is now a giant sphere of meat. It has a lot of latent energy (there are enough calories in the mole planet to support the Earth’s current population for 30 billion years). Normally, when organic matter decomposes, it releases much of that energy as heat. But throughout the majority of the planet’s interior, the pressure is over a hundred megapascals, which is enough to kill all bacteria and sterilize the mole remains—leaving no microorganisms to break down the mole tissues.
Closer to the surface, where the pressure is lower, there’s another obstacle to decomposition—the interior of a mole planet is low in oxygen. Without oxygen, the usual decomposition doesn’t happen, and the only bacteria that can break down the moles are those which don’t require oxygen. While inefficient, this anaerobic decomposition can unlock quite a bit of heat. If continued unchecked, it would heat the planet to a boil.
But the decomposition is self-limiting. Few bacteria can survive at temperatures above about 60 °C, so as the temperature goes up, the bacteria die off, and the decomposition slows. Throughout the planet, the mole bodies gradually break down into kerogen, a mush of organic matter which would—if the planet were hotter—eventually form oil.

Princeton University psych prof Susan Fiske published an open letter denouncing the practice of using social media to call out statistical errors in psychology research, describing the people who do this as “terrorists” and arguing that this was toxic because of the structure of social science scholarship, having an outsized effect on careers.
Blue writes, “Peter Watts has be stricken with debilitating pain, loss of range of motion and motor control. Watts’ doctors remain baffled despite a battery of tests, and Watts has reached out to his fans to ask for their theories and ideas as to what might be causing his illness.”
Today, I’ve launched a very special Kickstarter with two friends, Timothy Daly and Lawrence Azerrad. A year in the making (and many more years on our minds), the Voyager Golden Record: 40th Anniversary Edition is the first vinyl release of the stunning golden phonograph record launched by NASA in 1977 aboard the Voyager spacecraft, one […]
If you own a dog, you’ve most likely heard of BarkBox – the monthly subscription box for dogs. What started as a simple idea to try out the subscription model on pet owners has since developed a cult following of dog lovers. If you haven’t given it a try yet, this one month free deal is the […]
With the iPhone headphone jack having gone by the wayside, we’re excited about the addition of the FRANKLIN Bluetooth Headphones in our store. These headphones are foldable so they’re easy to carry around, but most importantly, they pack impressive sound. Our biggest struggle with Bluetooth headphones is the worry of them dying at the worst moment. This pair lasts an impressive 8-10 […]
