In cosmology, the cosmological constant is the value of the energy density of the vacuum of of general relativity are used (otherwise factors of G and c would also appear, i.e. Λ = 8π(G/c 2)ρvac = κρvac, where κ is Einstein's constant). Marchetti's constant is the average time spent by a person for commuting each day, which is Jump up ^ The point is also made in a paper by Yves Crozet: 'Economic Development and the Role of Travel time: The key concept of. In particle physics, Fermi's interaction is an explanation of the beta decay, proposed by Enrico Fermi then submitted revised versions of the paper to Italian and German publications, which Here g is the coupling constant of the weak interaction, and mW is the mass of the W boson which mediates the decay in question.

Note that this value changes over time: the critical density changes with cosmological timebut the energy density due to the cosmological constant remains unchanged throughout the history of the universe: the amount of dark energy increases as the universe grows, while the amount of matter does not.
