All today’s ideas are small minded physics singularity thinking. Since the great nothing of the universe has always been infinite in many dimensions, physicists can only describe what they see, and their questions only try to resolve field strengths, and densities. Size shouldn’t matter. What if this cycle start was infinite in size, and maximum density. There are few restrictions in the infinite nothing. Expansion continues everywhere infinitely into the infinite void, with no constraint, apart from forces of attraction. Don’t be restricted by limited maths and limited observation, and features of current status.
