1. The present universe is observed to be flat. Was it always flat, before it started its accelerated expansion?
2. Is the Riemann tensor zero for this flat universe? Is its geometry that of special relativity?
I'd appreciate if Marcus or Ich or any other science advisor weighed in on this. Thanks.
