      This assumes that the cosmos before our present one was constructed in much the same way as our current one. I see there are differences of opinion about recalling what might have been in a previous cosmos. It's sort of like saying - Here's an acorn. It will grow into a tree. All the force and character of the tree will be contracted into an acorn, the tree will die, the acorn will collapse but from its kernel will spring to life a new tree. Can we look at the acorn and see the old tree? Yes, DNA gives us that. But what about the tree before the first acorn? Was there a prior tree? We might assume so because we have an acorn. The acorn has all the DNA of what that prior tree might look like. But what if there was no tree prior? What if the acorn was created? Would we get the same result? Yes, we would.
      What if the kernel of the universe had the DNA of the universe for its life but had been created not rebounded? Would it appear any different?
