Locality and Non-locality
The following definitions provided by AI are influenced by Quantum Mechanics, which believes that SPACE is a void. According to the Theory of Substance, there is no such thing as a void. Space is always denotes dimensions of some substance. If there is space, there must be substance filling it. If there is no substance, there is no space either.

In physics, locality and non-locality refer to fundamental principles that describe how objects or particles interact with each other and their surroundings.
Locality
The principle of locality states that an object is influenced directly only by its immediate surroundings. This means that for one object to affect another, there must be some mediating force or particle that travels through the space between them. In the context of special relativity, locality implies that no influence can propagate faster than the speed of light.
Key aspects of locality include:
- Causes and effects are limited by the speed of light
- Interactions occur through fields or particles in the intervening space
- It aligns with our intuitive understanding of classical physics
Non-locality
Non-locality, particularly in quantum mechanics, refers to phenomena that appear to violate the principle of locality. The most notable example is quantum entanglement, where measuring the properties of one particle can instantaneously affect the properties of another particle, regardless of the distance between them.
Characteristics of non-locality in quantum physics:
- Entangled particles can exhibit correlations that seem to defy classical locality
- These correlations appear to occur instantaneously, regardless of spatial separation
- Non-local effects do not allow for faster-than-light communication of information
Implications
The tension between locality and non-locality has profound implications for our understanding of reality:
- It challenges our classical intuitions about cause and effect
- It has led to debates about the completeness of quantum mechanics, as highlighted by the EPR paradox
- Non-locality is crucial for quantum technologies like quantum computing and quantum cryptography
While non-locality in quantum mechanics seems to violate the principle of locality, it’s important to note that it does not actually allow for faster-than-light communication or violate the principles of special relativity. The apparent contradiction between these concepts continues to be a subject of research and philosophical debate in modern physics.
