Quantum entanglement is a phenomenon in quantum mechanics where two or more particles become correlated in such a way that the state of one particle cannot be described independently of the others. These particles can be separated by large distances, yet the state of one particle instantaneously affects the state of the other, violating classical notions of locality.
While the nature of quantum entanglement is still a subject of ongoing research and debate, it is not accurate to describe it as a "fold in the fabric of reality." The phrase "fold in the fabric of reality" is often associated with concepts like wormholes or bending of spacetime, which are related to general relativity rather than quantum mechanics.
Quantum entanglement is a fundamental aspect of quantum theory and is often considered a mysterious and counterintuitive phenomenon. It is not well-understood in terms of classical physics or our everyday experience of the world. However, it is a well-established and experimentally verified phenomenon that has been studied extensively in the field of quantum physics. Its implications have also led to developments in quantum information science, such as quantum computing and quantum cryptography.
