Quantum entanglement is a phenomenon in which two or more particles become correlated in such a way that the state of one particle cannot be described independently of the state of the others. It is a fundamental concept in quantum mechanics and has been experimentally confirmed.
While quantum entanglement is a puzzling phenomenon, it does not directly imply that the wave function is a description of the fabric of space or that measurement is a "looking glass" at space. The interpretation of quantum mechanics is a topic of ongoing debate among physicists, and there are various interpretations that attempt to explain the meaning and nature of the wave function.
The Copenhagen interpretation, which is one of the most widely accepted interpretations, views the wave function as a mathematical tool that provides probabilities for the outcomes of measurements. According to this interpretation, measurement collapses the wave function, and the result of the measurement is a definite value. However, the underlying nature of this collapse and the connection between the wave function and the fabric of space are not directly addressed.
Other interpretations, such as the Many-Worlds interpretation or the Pilot-wave theory, propose different explanations for the nature of the wave function and its relation to reality. These interpretations have their own assumptions and implications, but they also do not necessarily imply that the wave function is a description of the fabric of space itself.
In summary, while quantum entanglement is a fascinating phenomenon, it does not provide a direct proof that the wave function is a description of the fabric of space or that measurement is a "looking glass" at space. The interpretation of quantum mechanics remains an open question, and different interpretations offer different perspectives on the nature of the wave function and its connection to reality.
