Assuming a singularity at one point, light would not have very far to travel.lots of things could happen at that exact moment of creation/expansion.
Philosophical speculation, however, takes us away from the science of the matter. All we have to work with is what we can test, quantify, and observe.
As far as God goes, assuming God to exist, and assuming that a relationship is possible, there are many more important things on the agenda than mere mathematics. Perhaps we should be asking ourselves if it is logical,reasonable, and realistic for a faith to question new earth creationism. Why limit a Creator to obey the rules He allegedly created? Would such a Creator, assuming He/She/It is relational, frown upon humans attempting to understand science? We were given a brain, after all. Moreover,
should such a question not be in a philosophy/faith/belief forum?
