31--4, in which they explain that since we have no tested theory of quantum gravitation to supersede General Relativity nor any observational evidence for the existence of matter fields which violate the strong or weak energy conditions, the initial cosmological singularity has not been eliminated.

The caused beginning of the universe: a response to Quentin Smith

In various quantum gravitation models, such as string theory, loop quantum gravity, and non-commutative geometry, it is believed that there exists a minimum observable length, and this minimum observable length should have the order of the Planck scale.
