A Novel Equivalence Relation in Relativity
Nikkhah Shirazi, Armin
This paper proves a proposition which says that existence in a spacetime which meets four commonly satisfied principles is an equivalence relation by absolute dimensionality, and briefly discusses three of its implications: (1) the equivalence relation opens the serious possibility for things to exist in a physical sense without existing in spacetime, (2) it establishes a novel classical geometric correspondence between proper time intervals and Euclidean distances in a spacetime one dimension higher, and (3) it may serve as a theoretical tool for checking the internal consistency of higher-
dimensional models of reality.

Existence in Spacetime and the Lorentz Transformations (Slide set)
Nikkhah Shirazi, Armin
This talk introduces an equivalence relation that directly connects the concept of existence to physics. After introducing a reinterpretation of length contraction and time dilation, meant to bring attention to four spacetime principles which have so far not received much attention, the ontic equivalence relation is derived from the four principles. An important implication of the ontic equivalence relation is that it opens the possbility for something to exist without existing in spacetime. Also, though it is formally derived only for Minkowski spacetime, it may be applicable to a far wider range of spacetimes because the principles from which it is derived are so natural and obvious.

Toward Implementing Heisenberg's Distinction in the Quantum Formalism
Nikkhah Shirazi, Armin
"In his book "Physics and Philosophy", Heisenberg distinguished between the Quantum World as a realm of potentialities and the classical world as a realm of facts. As a matter of physics, his distinction has so far been barren, likely in part because there is no known underlying reason for why it needs to be there. In this talk, I report on a recent result which suggests such a reason, motivating the implementation of his distinction at the level of the quantum formalism. The underlying distinction offers a possibility for clarifying some aspects of the foundations of quantum mechanics and suggests, at least in principle, a novel and unexpected experimental prediction."

Lorentz transformations and Existence in Spacetime Slides
Nikkhah Shirazi, Armin
This talk a) introduces a novel interpretation of Lorentz contraction and time dilation, b) uses this reinterpretation to bring attention to four unappreciated spacetime principles, from which an ontic equivalence relation is derived, and c) touches on some interesting implications of the re-interpretation and the ontic equivalence relation.
This talk was given at the second Minkowski conference on the Foundation of Spacetime in Albena on May 16th, 2019, organized by the Minkowski Institute.
