Cosmological reconsiderations: The ontological status of Λ in the general theory of relativity.
Dillingham, Stephen G.

Cosmological reconsiderations: The ontological status of Λ in the general theory of relativity. - 135 p.

Source: Dissertation Abstracts International, Volume: 63-10, Section: A, page: 3582.

Thesis (Ph.D.)--The Johns Hopkins University, 2003.

In 1917, cosmological considerations—the apparent fact that the universe was static—led Einstein to modify the fundamental equation of the general theory of relativity by adding the so-called cosmological term. Einstein later renounced this modification in light of Hubble's observations, which provided evidence that the universe is expanding. Consequently, the cosmological term and the cosmological constant have been largely ignored in foundational work on the general theory of relativity.

520 $a In 1917, cosmological considerations—the apparent fact that the universe was static—led Einstein to modify the fundamental equation of the general theory of relativity by adding the so-called cosmological term. Einstein later renounced this modification in light of Hubble's observations, which provided evidence that the universe is expanding. Consequently, the cosmological term and the cosmological constant have been largely ignored in foundational work on the general theory of relativity.
520 $a Recently, however, astronomical evidence has suggested that the cosmological constant is actually nonzero. In light of this, a re-examination of pertinent philosophical work is called for. In this dissertation, I examine the relationship between the cosmological constant and Hans Reichenbach's notion of universal forces and J. L. Anderson's and Michael Friedman's concept of absolute objects. I conclude that although it appears to be at first, the cosmological constant is not a universal force in Reichenbach's sense. It is, however, an absolute object in the sense of Anderson and Friedman. This conclusion does not require us to reject their view that relativity principles are symmetry principles, but it removes an important motivation for the view.
