Software

How can we predict that Earth is accumulating or shepherding dark matter? We need a method to support that prediction. Better yet, can we quantify that prediction: how is the dark matter distributed? What shape does it take? If we can predict how dark matter clusters near the Earth, we can assist planning terrestrial dark matter experiments. If we show how dark matter accumulates in orbit, we lay the foundation for planning space missions that observe dark matter in space. For this project, we use a software simulation to predict the details of how dark matter interacts with the Earth, named Dark matter Object ORiented Simulation Tool with Extended Precision, or simply DOORSTEP.
