Tähänkin tarvittiin tutkimus: Super Mario Galaxy ei seuraa fysiikan lakeja!

Fysiikan ja astronomian laitoksen tutkijat Leicesterin yliopistossa ovat selvittäneet, voisivatko Super Mario Galaxyn pienoisplaneetat olla todellisuudessa mahdollisia.

It's a me, Density! -niminen tutkimus toteaa, että pelin pienoisplaneetat romahtaisivat gra... gravitaationaalisen paineen epätasapainon takia? Couloumb-paineetkin ovat jotenkin osatekijänä. Ehkä parempi, että tutkijat itse saavat selittää asian laidan:

With an approximate radius for these planets set at 50m, the required density to maintain Earth-like surface gravity is calculated and compared to known super-dense structures such as white-dwarfs. The stability of such a planet is then discussed and it is concluded that it would likely explode due to the severe imbalance of gravitational pressure to degeneracy and coulomb pressures.

Although a pleasant idea, none of the above could ever truly come to pass. Clearly, the degeneracy pressure far outstrips the gravitational pressure by eleven orders of magnitude. The outcome of this discrepancy is that if constructed, the planet would survive for only a very brief moment before violently destroying itself and any short plumbers who happen to be running about on its surface.
