The phenomenon you're referring to is known as quantum entanglement. In quantum mechanics, entangled particles such as photons exhibit correlations in their properties, such as their spin or polarization, that are seemingly connected regardless of the distance between them. However, it is important to note that quantum entanglement does not imply a direct physical connection or communication between the particles through higher dimensions or any other mechanism.
The behavior of entangled particles can be mathematically described by a quantum state that encompasses the entire system. When two particles are entangled, their states become linked in such a way that measuring the state of one particle instantaneously affects the state of the other, regardless of the spatial separation between them. This behavior has been observed experimentally and is well-established in the field of quantum physics.
However, it is crucial to understand that entanglement does not enable faster-than-light communication or violate causality. The entangled particles do not transmit information between each other in a classical sense, and any attempt to use them for communication would not be successful.
The nature of the underlying mechanism that allows entanglement to occur is still a topic of scientific inquiry and debate. Various interpretations and theories exist, such as the Copenhagen interpretation, many-worlds interpretation, and hidden variable theories. However, there is no consensus on a definitive explanation for entanglement.
While there are speculative theories that propose extra dimensions or hidden variables to explain entanglement, these ideas remain speculative and have not been supported by empirical evidence thus far. Quantum entanglement can be described and understood within the framework of quantum mechanics, which operates within our four dimensions of spacetime.
