The Mystery of the Varying Cosmological Constant (and What to Possibly Do about It)

I recently read an article by Jesus Mosterin, called “The Unity of Particle Physics and Cosmology?” (pg. 165-176 in The Problem of the Unity of Science edited by Agazzi and Faye). The article is very interesting, because it proposes something I hadn’t heard before, namely, that the Casimir effect might be the phenomenon that is the conceptual key to unifying quantum and cosmological scales.  The idea is that vacuum energies associated with a cosmological constant, Λ, might be the cause of the effect (there are numerous interpretations); but there is/are a problem(s), which has been noted by Steven Weinberg, Alan Guth, and others.  In particular, the one that immediately comes to the fore is the problematic nature of the consequences of a varying cosmological constant.  (Keep in mind that the early universe seemed to have an enormous vacuum energy present, while, now, all we have is this rinky-dink Casimir effect of quantum mechanical origin.)  Continue reading

Flat Ontology and the Onto-epistemic Stance

I have been working on an idea for a seminar, entitled “Unity of Science,” which involves collapsing epistemology and ontology into one branch of philosophy.  The paper is called, “Abstraction as Dissection of a Flat “Ontology”: The Illusiveness of Levels” (click this sentence to view paper).  One of the motivations for doing this is that I think pragmatism and theory-ladenness call for it; and the two notions, themselves, seem to be naturally married by van Fraassen’s pragmatics of explanation —not to mention having been sort of suggested by Peirce.  I say “sort of” because theory-ladenness hadn’t been thought of, back then.
