Premise: Imagine that we could travel to an alternate universe, and bring enough of our own universe to maintain a reality(Possibly utter hogwash, but I am attempting to write fiction), and that universe diverged from ours at the point that the hydrogen atoms had formed. Due to a slight difference in gravity, the atoms never coalesced into the densities required to become stars. My question: Can you help describe a universe like that? Would there be light at all? Would it be like a universal atmosphere? Secondary thought: Is it possible for gravity to be different enough from what we know that the atoms could coalesce into greater densities but not achieve fusion? Thank you for your time.
Here are my thoughts assuming a universe our size with the same amount of mas/energy. There would be no visible light. Yes, but that universal atmosphere would be a vacuum greater than we can achieve in the laboratory on earth. I suppose so, it is a different universe.
