Neal Stephensons exploding Moon simulated

Vor ein paar Tagen schrieb ich ein paar Worte zu Neal Stephensons Amalthea (eng. Seveneves) in dem der Mond explodiert, die Bruchstücke immer weiter fragmentieren und schließlich als Meteorschauer die Oberfläche der Erde ausradieren.

Jason Cole hat nun mal nachgesehen, wie realistisch dieses Szenario ist und ob Stephenson richtig gerechnet hat: The moon blew up without warning and for no apparent reason (via Jason Kottke)

One of the events depicted in the book is the ‘white sky’, where the number of impacts grows exponentially until they are near-constant. Plotted on a logarithmic scale, there does appear to be an initial exponential phase in the simulation, lasting a relatively short time. Soon after, the impact rate slows but not to zero, with impacts occurring every so often for the remainder of the simulation. This is another scenario predicted in the book, where the planet takes many thousands of years to cool down after the initial heavy bombardment.
