Close approximate structure and functioning
Close approximate structure and functioning refers to a body of matter like a human body that is different from an original body in space and, or time, and in its content in matter and energy that the alternate body is made of. Close approximate structure and functioning can range in structure from a singular subatomic difference in one atom to enumerable but finite differences in orientation, position, and compositions etc., in molecules, to differences in the structure of the neurons and other cells, to major changes is body parts like arms legs, skin and organs. There are many variations in environmental conditions that effect the functioning of the body given a particular structure. Given one unique set of environmental conditions and one unique body structure Two different bodies functioning can still vary over time because of differences in to the unique set of differing quantum probabilistic variations occurring within the two bodies.
Superimmortality predicts that there are many different structures and functioning of matter that can be produced in different bodies that will produce the same consciousness and ixperiencitness And even more structures and functioning of matter that can be produced in different bodies, that will produce a different consciousness but nonetheless the same ixperiencitness.
