The goal of the meteors project was to give a sense of how often damaging meteors strike the earth.
Data for this project was not readily available, so one of the exciting challenges on this project involved researching what scientists have extrapolated about the frequency of meteor strikes. Using formulas devised by scientists at Harvard, Purdue and the Imperial College of London, the frequency of meteor strikes in the simulation is calculated based on the energy of the meteors. The energy of incoming meteors is a somewhat abstract concept to most readers, so a fixed density and velocity for the meteors was chosen. This allowed size to be used as the measure, which resonates well with users. The result is a simulation that shows the frequency of meteor strikes by size over the span of 100 million years, and tells users how their run of the simulation compares to the theoretical average.
