What If Matter Could Have A Negative Mass
... What If? There is some strange behavior that would come from applying forces to negative masses. For instance, it would become very difficult to control the object. When pushed, the object accelerates towards whatever is pushing it. But this results in the initial force continuing, because the objec ...
