Abstract

SILVA, P. R.. Cosmological constant and polymer physics. Braz. J. Phys. [online]. 2008, vol.38, n.4, pp.587-590. ISSN 0103-9733.  http://dx.doi.org/10.1590/S0103-97332008000500010.

It is traced out a parallel between the cosmological constant problem and the polymer physics. The time evolution of the universe world line is compared with the growing of a polymer chain. An equivalent Flory free energy and a modification of it are used as a means to evaluate two versions for the "radius of gyration" of the universe. It is proposed a link between this radius of gyration and the cosmological constant parameter.

Keywords : Cosmological constant; Polymer chain; Universe world line; Planck length; Space-time; Dark energy; Flory's model.
