At the Planck scale, which is the scale where quantum gravity effects are expected to become significant, our current understanding of physics is limited. The nature of space and the behavior of matter at such scales are still subjects of active research and remain poorly understood.
In our current understanding of physics, the behavior of particles and fields is governed by fundamental laws and equations. These laws, such as those of quantum mechanics and general relativity, describe how particles and fields interact and evolve over time. However, the specific mechanisms by which adjacent regions of space "communicate" or "interact" at the Planck scale are not yet fully understood.
One possible approach to addressing this question is through the concept of quantum entanglement. Quantum entanglement is a phenomenon in which the quantum states of two or more particles become correlated in such a way that the state of one particle cannot be described independently of the others. This means that the behavior of one particle can be influenced by the behavior of another particle, even if they are separated by large distances.
It is hypothesized that quantum entanglement could play a role in the interconnection of regions of space at the Planck scale, allowing for a form of "communication" or "information transfer" between adjacent regions. However, the details of how this would work in the context of a complete theory of quantum gravity are still the subject of ongoing research and are not yet fully understood.
It's important to note that our understanding of the behavior of space and matter at the Planck scale is highly speculative, as we currently lack a complete theory that incorporates both quantum mechanics and gravity consistently. Research in the field of quantum gravity aims to develop such a theory that can provide a deeper understanding of the fundamental nature of space and its interactions at the most fundamental scales.
