Well-proportioned universes suppress the cosmic microwave background quadrupole

Résumé

A widespread myth asserts that all small universe models suppress the cosmic microwave background (CMB) quadrupole. In actual fact, some models suppress the quadrupole while others elevate it, according to whether their low-order modes are weak or strong relative to their high-order modes. Elementary geometrical reasoning shows that a model's largest dimension determines the rough value lmin at which the CMB power spectrum l(l + 1) Cl/2pi effectively begins; for cosmologically relevant models, lmin
