  1. On the Ontology of Spacetime: Substantivalism, Relationism, Eternalism, and Emergence.Gustavo E. Romero - 2017 - Foundations of Science 22 (1):141-159.
    I present a discussion of some issues in the ontology of spacetime. After a characterisation of the controversies among relationists, substantivalists, eternalists, and presentists, I offer a new argument for rejecting presentism, the doctrine that only present objects exist. Then, I outline and defend a form of spacetime realism that I call event substantivalism. I propose an ontological theory for the emergence of spacetime from more basic entities. Finally, I argue that a relational theory of pre-geometric entities can give rise (...)

  • Adversus Singularitates: The Ontology of Space–Time Singularities.Gustavo E. Romero - 2013 - Foundations of Science 18 (2):297-306.
    I argue that there are no physical singularities in space–time. Singular space–time models do not belong to the ontology of the world, because of a simple reason: they are concepts, defective solutions of Einstein’s field equations. I discuss the actual implication of the so-called singularity theorems. In remarking the confusion and fog that emerge from the reification of singularities I hope to contribute to a better understanding of the possibilities and limits of the theory of general relativity.

  • L'ontologie des singularités.Nicolae Sfetcu - manuscript
    La relativité générale permet les singularités et nous devons comprendre l'ontologie si nous voulons comprendre la nature de l'espace et du temps dans l'univers d'aujourd'hui. Bien que certains physiciens pensent que les singularités indiquent un échec de la relativité générale, d'autres pensent que les singularités ouvrent un nouvel horizon dans la cosmologie, avec de réels phénomènes physiques pouvant contribuer à un progrès profond dans notre compréhension du monde.

  • Present Time.Gustavo E. Romero - 2015 - Foundations of Science 20 (2):135-145.
    The idea of a moving present or ‘now’ seems to form part of our most basic beliefs about reality. Such a present, however, is not reflected in any of our theories of the physical world. I show in this article that presentism, the doctrine that only what is present exists, is in conflict with modern relativistic cosmology and recent advances in neurosciences. I argue for a tenseless view of time, where what we call ‘the present’ is just an emergent secondary (...)

  • The Ontology of General Relativity.Gustavo E. Romero - forthcoming - In M. Novello & S. E. Perez Bergliaffa (eds.), General Relativity and Gravitation. Cambridge University Press.
    I discuss the ontological assumptions and implications of General Relativity. I maintain that General Relativity is a theory about gravitational fields, not about space-time. The latter is a more basic ontological category, that emerges from physical relations among all existents. I also argue that there are no physical singularities in space-time. Singular space-time models do not belong to the ontology of the world: they are not things but concepts, i.e. defective solutions of Einstein’s field equations. I briefly discuss the actual (...)

  • A Formal Ontological Theory Based on Timeless Events.Gustavo Romero - 2016 - Philosophia 44 (2):607-622.
    I offer a formal ontological theory where the basic building blocks of the world are timeless events. The composition of events results in processes. Spacetime emerges as the system of all events. Things are construed as bundles of processes. I maintain that such a view is in accord with General Relativity and offers interesting prospects for the foundations of classical and quantum gravity.

  • Sufficient Reason and Reason Enough.Gustavo Romero - 2016 - Foundations of Science 21 (3):455-460.
    I offer an analysis of the Principle of Sufficient Reason and its relevancy for the scientific endeavour. I submit that the world is not, and cannot be, rational—only some brained beings are. The Principle of Sufficient Reason is not a necessary truth nor a physical law. It is just a guiding metanomological hypothesis justified a posteriori by its success in helping us to unveil the mechanisms that operate in Nature.

  • The Collapse of Supertasks.Gustavo E. Romero - 2014 - Foundations of Science 19 (2):209-216.
    A supertask consists in the performance of an infinite number of actions in a finite time. I show that any attempt to carry out a supertask will produce a divergence of the curvature of spacetime, resulting in the formation of a black hole. I maintain that supertaks, contrarily to a popular view among philosophers, are physically impossible. Supertasks, literally, collapse under their own weight.

  • Mario Bunge on Gravitational Waves and the Reality of Spacetime.Gustavo E. Romero - 2018 - Foundations of Science 23 (2):405-409.
    I discuss the recent claims made by Mario Bunge on the philosophical implications of the discovery of gravitational waves. I think that Bunge is right when he points out that the detection implies the materiality of spacetime, but I reject his identification of spacetime with the gravitational field. I show that Bunge’s analysis of the spacetime inside a hollow sphere is defective, but this in no way affects his main claim.
