found: Oxford Reference Online, Feb. 25, 2005(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.)

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)
