Quantum cosmology

quantum cosmology
The study of the earliest moments of the universe after the Big Bang, a stage known as the Planck era. Because this field demands an understanding of how spacetime behaves at the quantum level, and there is not yet an adequate quantum theory of gravity, it is highly speculative.

Quantum Cosmology
The study of the very earliest stages of the Universe after the Big Bang, including the properties of the initial singularity and of the Planck era in general. This field is highly speculative since it requires an understanding of quantum gravitational effects, and there is as yet no satisfactory theory of quantum gravity.

In theoretical physics, quantum cosmology is a field attempting to study the effect of quantum mechanics on the formation of the universe, or its early evolution, especially just after the Big Bang. Despite many attempts, such as the Wheeler-deWitt equation, the field remains a rather speculative branch of quantum gravity.
An important problem in this field is the origin of physical information in the universe.
