By studying the geometry of model space-times, researchers offer alternative views of the universe’s first moments.

This is fascinating and highly promising research: A team of mathematicians take a closer look under which conditions a singularity might occur and have already identified a taxonomy of curvatures, one of which is termed a ‘coordinated one’, which only arises due to the (volitional) placement of constraints in terms of coordinates, another one a physical one. Much of their ideas is derived from Hawkings’ and other earlier work describing the laws of nature surrounding a black hole, like e.g. in which ways those laws must be described near or past the even horizon.
Ghazal Geshnizjani of the Perimeter Institute, Eric Ling of the University of Copenhagen, and Jerome Quintin of the University of Waterloo recently published a paper in the Journal of High Energy Physics in which, Ling said,
“we mathematically showed that there might be a way to see beyond our universe.”
Peering back beyond the beginning of our known universe with still a number of unresolved and unreconciled issues between two well proven theories, i.e. General Relativity and the Standard Model of the Universe as well as Quantum Physics, is at the very least a bold endeavour and one that might eventually help us really understand what place we’re in.
