The force that causes particles to become entangled is not a force in the traditional sense, but rather a property of quantum mechanics known as quantum entanglement. Entanglement occurs when two or more particles become correlated in such a way that the quantum state of one particle is dependent on the state of the other, regardless of the distance between them. However, entanglement is not caused by a force that we are familiar with in classical physics.
Quantum entanglement is a fundamental aspect of quantum theory and is often described as a non-local phenomenon. It means that the entangled particles can instantaneously affect each other's states, even if they are separated by large distances. This behavior seems to violate our classical intuition and the principle of locality, which states that information cannot travel faster than the speed of light. However, it is important to note that entanglement cannot be used to transmit information at superluminal speeds.
The underlying mechanism behind entanglement is not fully understood, and it remains a subject of ongoing research in quantum physics. However, it is widely accepted that entanglement arises from the probabilistic nature of quantum mechanics and the mathematical formalism used to describe quantum states. It is a fundamental feature of the quantum world and has been experimentally verified through numerous experiments.
