Does the cosmological constant support MOND? The equation for critical density is as follows (in terms of mass rather than density): Critical density (90.4 x e54 gm) = matter (4.1 x e54 gm) + dark matter (20.6 x e54 gm) + dark energy/cosmological constant (65.7 x e54 gm). Most estimates for matter are in the range of e55 gm (or more) which is close to the total for matter and dark matter (2.64 x e55 gm). Thus, dark matter may not exist and MOND may be a correct theory. Comments?
