The Potential of a Thick Present through Undefined Causality and Non-Locality

Abstract

This paper elaborates on the interpretation of time and entanglement, offering insights into the possible ontological nature of information in the emergence of spacetime, towards a quantum description of gravity. We first investigate different perspectives on time and identify in the idea of a “thick present” the only element of reality needed to describe evolution, differences, and relations. The thick present is connected to a spacetime information “sampling rate”, and it is intended as a time symmetric potential bounded between a causal past of irreversible events and a still open future. From this potential, spacetime emerges in each instant as a space-like foliation (in a description based on imaginary paths). In the second part, we analyze undefined causal orders to understand how their potential could persist along the thick present instants. Thanks to a C-NOT logic and the concept of an imaginary time, we derive a description of entanglement as the potential of a logically consistent open choice among imaginary paths. We then conceptually map the imaginary paths identified in the entanglement of the undefined orders to Closed Time-like Curves (CTC) in the thick present. Considering a universe described through information, CTC are interpreted as “memory loops”, elementary structures encoding the information potential related to the entanglement in both time and space, manifested as undefined causality and non-locality in the emerging foliation. We conclude by suggesting a possible extension of the introduced concepts in a holographic perspective.

The Universe as a Telecommunication Network

“…Among the several works in the recent literature, we base our research on the physics interpretations of Presentism given in Ref. [3], [4], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22] and the philosophical perspectives of Ref. [23], [24], [25].…”

“…In Ref. [4] it is considered as holographically equivalent to an entanglement between nodes (ER=EPR, also inspired by Ref. [5] and [6]).…”

“…In the context of Ref. [12] and [4], we model fermions from their non-locality. Given a fermion in empty space with Center of Momentum (CoM) at a node X, we describe its forward and backward waves as a probabilistic bundle of CTCs in the Present.…”

“…The indeterminacy of order along the 2 sides of the imaginary space in 2 successive cycles can be expressed with a XOR logic |↑↓⟩ ⊕ |↓↑⟩ and represents a logically consistent information (no over or under-determined solutions) and an entanglement in time of 2 instants, as introduced in Ref. [4].…”

“…In the context of a Presentism approach to evolution, extending a previous paper on time and entanglement reported in Ref. [4], we will design a fundamental network evolving in discrete steps and encoding the information of distance and entanglement among far atoms of space. This elementary network is not given as spacetime itself, nor is a "stage" for particles.…”
