## What is Rubble!?

Asteroids can be single rocks, or clumps of smaller rocks held together by their mutual gravity.   And a bunch of them are headed towards Earth!  Your job:  use bombs and impactors to deflect them away from Earth before time runs out.  Humanity is depending on you!  And remember: those movies where they just blow up the asteroid and the pieces don’t matter?  That doesn't actually work. 

This is a simple, one level game built on the Box2D physics engine.  Individual asteroids are attracted to each other by their mutual gravity in a physically consistent way.  For teachers:  Rubble! can be used as an educational game to supplement classroom discussions on asteroids, comets, Earth impacts, and gravity as a universal force.  Development was supported through grants by the National Science Foundation and NASA.
