World objects are then sub-parts of the universe.\nThe fundamental distinction between world objects, upon which the EMMO is based, is self-connectedness: a world object can be self-connected xor not self-connected.\nParthood relations do not change dimensionality of the world object: every part of a world object is another world object and always retains a 4D dimensionality character.\nThe smallest part of a world object (i.e. a part that has no proper parts) is called a 'Quantum' individual. Quantum individuals are the fundamental causal constituents of the universe. They are no-dimensional, and their aggregation makes 4D objects emerge from their causal structure.\nIt follows that, for the EMMO, world objects of dimensionality lower than 4D (e.g. surfaces, lines) do not exist.\nIn the EMMO there are no relations such as occupiesSpace, since objects are themselves the 4D regions.\nAn object always possess 4-dimensions. It follows from the fact that perception is always unfolding in time (e.g. you always have an aperture time when you take a picture or measure a property. Instantaneous perceptions are idealizations (abstractions) or a very small time measurement).@en"] OSW802d3e9287704f98a289ccaaab7fdddf# ERR0cf8c53d7c740a4d5c6eafb6f7e19495 Collection 14 en OSW2d2ecd97067f4d0e950cd746b7700a31 Item 14 en OSWeb3a768ed53e4be9a23b0714833c36de SubClassOf 102 en SubClassOf
