Abstract
- 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.<br />Comment: 6 pages, no figures
