Three possible implications of spacetime discreteness
spacetime discreteness Planck scale, speed of light gravity wavefunction collapse quantum gravity
2016/6/13
We analyze the possible implications of the discreteness of spacetime, which is defined here as the existence of a minimum observable interval of spacetime. First, it is argued that the discreteness o...
In this paper I consider possible causation, specifically, would-cause counterfactuals of the form ‘had an event of kind A occurred, it would have caused an event of kind B’. I outline some difficulti...
Gauge-Invariant Localization of Infinitely Many Gravitational Energies from All Possible Auxiliary Structures

The problem of finding a covariant expression for the distribution and conservation of gravitational energy-momentum dates to the 1910s. A suitably covariant infinite-component localization is display...
Is Structural Underdetermination Possible?
structural realism theory underdetermination theories of gravity
2009/4/8
Structural realism is sometimes said to undermine the theory underdetermination (TUD) argument against realism, since, in usual TUD scenarios, the supposed underdetermination concerns the object-like ...
Illusions in quantified reasoning: How to make the impossible seem possible, and vice versa
Illusions in quantified reasoning impossible possible vice versa

The mental model theory postulates that reasoners build models of the situations described in
premises, and that these models normally represent only what is true. The theory has an unexpected
