Blueberry Earth
Anders Sandberg
(Submitted on 27 Jul 2018)

This paper explores the physics of the what-if question "what if the entire Earth was instantaneously replaced with an equal volume of closely packed, but uncompressed blueberries?" While the assumption may be absurd, the consequences can be explored rigorously using elementary physics. The result is not entirely dissimilar to a small ocean-world exoplanet.

Очень вспомнился пост на what-if xkcd про mole of moles - с теми же выводами и почти в том же масштабе )))

забавно, не видел такого раньше.
Моль моли уже не так круто.

Там моль кротов (moles - это они), именно потому и получается размером с Галилеевы спутники)))

"The planet would start off uniformly lukewarm—probably a bit over room temperature—and the gravitational contraction would heat the deep interior by a handful of degrees.

But this is where it gets weird.

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..."
