Poromera

Poromera is a term in theoretical particle physics related to the concept of emergent spacetime. It refers to a hypothetical parameter or set of parameters that describes the fundamental degrees of freedom from which spacetime itself might emerge.

In many models of emergent spacetime, spacetime is not considered a fundamental entity, but rather an approximation that arises from the collective behavior of more fundamental constituents. These constituents and their interactions are governed by rules that may be very different from the physics we observe at macroscopic scales. The poromera (or poromera set) would then parameterize these underlying rules and determine the properties of the emergent spacetime.

The precise nature of the poromera is highly model-dependent and subject to ongoing research. Different approaches to emergent spacetime, such as those based on condensed matter analogs, quantum gravity, or string theory, may posit different types of fundamental constituents and therefore different poromera.

The study of poromera is aimed at understanding how the observed properties of spacetime, such as its dimensionality, metric signature, and connection to gravity, can arise from more fundamental principles. It is a key area of investigation in the search for a theory of quantum gravity and a deeper understanding of the nature of reality.
