EMMO

The EMMO conceptualises the world using the primitive concepts of causality and parthood. Parthood is about the composition of world entities starting from other more fundamental entities. Causality is about the interactions between world entities. The quantum is the smallest indivisible part of any world entity. Quantum individuals are the fundamental causal constituents of the universe, since it is implied that causality originates from quantum-to-quantum interactions. Quantums are no-dimensional, and their aggregation makes spacetime emerge from their causal structure. We can think of a quantum as an elementary particle after and interaction and before another interaction. Causality between macro entities (i.e. entities made of more than one quantum) is explained as the sum of the causality relations between their quantum constituents. Fundamental interactions (quantum fields) are represented as symmetric causality relation between macro entities, while classical interactions are mediated by chain of quantums (i.e. elementary particles). The fundamental distinction between world entities is causality self-connectedness: a world entity can be self-connected xor not self-connected depending on the causality network of its fundamental components. Void regions do not exist in the EMMO. In other words there is no spacetime without entities and spacetime emerges as relational property not as a self-standing entity). Entities are not placed in space or time: space and time are measured quantities, always relative between entities and are measured. In other words, space and time relations originates from causality interactions.

The disjoint union of the fundamental mereocausal classes of Quantum, CausalPath, CausalSystem and Collection.

DisjointUnion: CausalPath, Collection, Quantum, CausalSystem

The class of all the OWL individuals representing world entities according to EMMO conceptualisation.

EMMO entities dimensionality is related to their mereocausal structures. From the no-dimensional quantum entity, we introduce time dimension with the elementary concept, and space with the causal system concept. The EMMO conceptualisation does not allow the existence of space without a temporal dimension, the latter coming from a causal relation between entities. For this reason, the EMMO entities that are not quantum or elementaries, may be considered to be always 4D spatiotemporal entities. Moreover, the combination of mereology and causality used in the EMMO theory (mereocausality) represents entities as direct acyclic graphs with dimension of 4 (i.e., the mereocasual graph can be represented in a 4D euclidian space with edges having unit length). For this reasons, the EMMO can be considered a 4D ontology.
