When a missile or meteorite strikes the earth, the destruction caused can be observed on the surface easily but what happens underground is harder to detect. To study the same, a new technique has been developed by the physicists of Duke University in which they stimulated high speed impacts using artificial sand and soil and used high speed cameras for recording the strikes. The impacts were then played back in super slow-motion or frame by frame. The research was funded by Defense Threat Reduction Agency.

Researchers observed that the harder the soil and sand are struck, the harder they become. They explained that this is the reason why the ground penetrating missiles which strike the land harder and faster achieve limited success, as they experience resistance and finally stop. This research may hel...
