摘要: Abstract Surveys of the microwave background indicate that universe is isotropic to more than one part in 10 5 . Due arbitrariness initial conditions at big bang singularity cannot predict this; it usually put by hand. We therefore construct quantum cosmology an anistropic according “no-boundary” prescription Hartle and Hawking. Such a model has well-defined behavior classical singularity. then show also implies large universe, such as ours, isotropic.
