Collision Course is a term used to describe two objects or forces that are on a path to meet and interact with each other, often with disastrous consequences. The term is often used to describe a situation in which two people or groups have opposing goals and are likely to clash. The term can also be used to describe two objects in space, such as asteroids, that are on a trajectory to collide with each other. The term 'ENCOUNTER' is often used synonymously with collision course, as it implies the same idea of two objects or forces coming together.
