👉 Counterend is a concept in physics that describes an object or system that has no end. This means that it can exist without any external forces, such as gravity, and continue to move indefinitely. Counterends are often used in the context of quantum mechanics, where they represent hypothetical objects that do not have a definite start or end point. Counterends are fundamental to the concept of quantum entanglement, which is the phenomenon by which particles become linked in ways that cannot be separated or isolated from each
