I also point at the idea of "fluctuating" universe, meaning that a Big bang forms an expanding universe, expansion turns into retraction and final collapse of all thing in one single point - and that marks the next Big Bang and the cycle begins from start.
The problem of astronmy and physics with Big Bang and empty voids, a noithingness, is, that a "nothing" despite being nothing and being beyond any content and characteristics, nevertheless must have such features and characteristics that makle this nothing suddenly causing something and giving birth to time and energy. this is the line that marks the beginning of territories that neither science nor relgions do have explanations for. Science cannot explain it and is never much concerned about the questions of "Why?", only about "How?". Relögions just claims something without any ground or basis and takes that arbitrary claim as "truth".
The truth is that there are things that we simply do not know, scientists and religious people all alike. The option that recommends itself here is: to just admit that.

Have rough knowledge of this, but we can "listen" at least to some of the furthest regions of the universe with radio telescopes. Anyways, lets not get into a in-depth discussion about the complexities astrophysics, and lets be amazed at the wonders of the universe
