The Perimeter Institute is an interesting think tank for cosmology related items. Some of their astrophysicists recently published a paper on the creation of the proximal Universe from white hole. The idea is that instead of a big bang a star in a Universe with a higher dimensions collapsed to form a black hole with one extra dimension. The event horizon chaff of that event is the material of this Universe that is expanding. Interesting idea that higher-dimensional Universe force fields could account for some inexplicable things like the expansion of this Universe with dark energy, and possibly dark matter too. Parmenides and Heraclitus thought about such matters- Parmenides in particular anticipated the spinning bucket thought experiment in a sense. Here is the paper and another with a different idea about black holes. https://arxiv.org/pdf/1309.1487.pdf
I should mention that as a Christian I haven't a problem with various cosmology theories. The Let There Be Light paradigm covers quite a bit of theoretical spatial configurations.
