Non-locality and the Bekenstein bound?

In summary, the conversation discusses the concept of information content and its relation to locality and non-locality. The rule for objectivity is that no two observers' realities can be inconsistent with each other, and "complete" information only refers to access to all locally available information. Non-local entanglement cannot be used for information transmission, and it is unclear where information actually resides. The expansion of boundaries can reveal new information, but its exact location is still a mystery.

On one side, the amount of information is bounded above for any fixed volume of space: this would seem (?) to indicate that information content is local. Yet physical states are not necessarily local, as non-local entanglement shows. So how do you have local information content of a non-local state?
:confused:

I saved the following which I liked a lot from another discussion in these forums:

The rule for objectivity is not that everyone lives in the same reality, it is that no two observers' realities can be inconsistent with each other. This also means that "complete" information does not imply a unique description of the reality, it merely implies access to all the information that is locally available to that observer in principle. The locality of the information is what preserves causality…”

Naty1, interesting quote. I shall mull it over. Thanks.

As you probably know, anything outside your timelike [causal] light cone has no effect on you...all the 'space like' stuff is non casual...

and as you also probably know, non local entanglement cannot be used to convey information...
it happens, but we can't utilize it for information transmission.

Also, note that for any 'fixed volume of space' boundary, all you have to do is expand that boundary take a new look, and, viola, all the information resides on the new, larger boundary, along with some new...Just where information 'resides' is not all that clear according to Leonard Susskind.

All in all very intriguing!
 

Related to Non-locality and the Bekenstein bound?

1. What is non-locality?

Non-locality is a concept in physics that describes the ability of objects to influence each other instantaneously, regardless of the distance between them. This phenomenon challenges the principle of locality, which states that objects can only interact with each other through their immediate surroundings.

2. How does non-locality relate to the Bekenstein bound?

The Bekenstein bound is a theoretical limit on the amount of information that can be contained in a given space. Non-locality is relevant to this concept because it suggests that information can be transmitted beyond the boundaries of this space, violating the bound.

3. What is the significance of the Bekenstein bound in physics?

The Bekenstein bound is important because it provides a limit on the amount of information that can be stored in a given space. This has implications for black hole thermodynamics and the information paradox, as well as other areas of physics such as quantum gravity and string theory.

4. Is there evidence for non-locality and the Bekenstein bound?

There is currently no direct experimental evidence for non-locality or the Bekenstein bound. However, there have been several thought experiments and theoretical models that support these concepts. The phenomenon of entanglement in quantum mechanics is often cited as evidence for non-locality, and the holographic principle in string theory is based on the Bekenstein bound.

5. How do scientists reconcile non-locality and the Bekenstein bound with the theory of relativity?

The theory of relativity states that information cannot travel faster than the speed of light, which appears to contradict the concept of non-locality. However, some theories, such as the many-worlds interpretation of quantum mechanics, propose that non-locality can be explained by parallel universes or hidden variables that do not violate the laws of relativity. The Bekenstein bound also does not necessarily contradict relativity, as it is a theoretical limit and not a physical one.
