What Becomes of a Causal Set?

Unlike the relativity theory it seeks to replace, causal set theory (CST) has been interpreted to leave space for a substantive, though perhaps ‘localized’, form of ‘becoming’. The possibility of fundamental becoming is nourished by the fact that the analogue of Stein’s theorem from special relativity does not hold in CST. Despite this, we find that in many ways, the debate concerning becoming parallels the well-rehearsed lines it follows in the domain of relativity. We present, however, some…

Causal set theory attempts to formulate a quantum theory of gravity by assuming that the fundamental structure is a discrete set of basal events partially ordered by causality. In other words, it…
On the Modal Aspects of Causal Sets
- PhilosophyFoundations of Physics
- 2019
This paper interpret causal sets as multi-realisable objects, like states, which is undermined by an argument for the probabilistic constraint of general covariance, as it says that multiple paths along which a causal set is produced are not physically different.

A precipice below which lies absurdity? Theories without a spacetime and scientific understanding
- Philosophy, PhysicsSynth.

The contextual theory of scientific understanding is adapted to fit the novel challenges posed by physical theories without spacetime and it is argued that such physical theories can provide scientific understanding, and that such understanding does not require spacetimes of any sort.

General Relativity traces the evolution of our Universe back to a Big Bang singularity. To probe physics before the singularity—if indeed there is a “before”—we must turn to quantum gravity. The…

The definability of objective becoming in Minkowski spacetime
- PhilosophySynthese
- 2005
It is shown that Stein's uniqueness proof can be extended in a natural way to cover this more general kind of becoming, provided one does not enrich standard Minkowski spacetime by privileging certain sets of worldlines over others in an unwarranted manner.

The birth of spacetime atoms as the passage of time
- PhilosophyAnnals of the New York Academy of Sciences

It is suggested that the reason there is no consensus on whether the passage of time is physical is that the current best theory of spacetime, general relativity, lacks the concept of passage, which means that the sense‐experience of passage cannot be properly expressed.
