Where is the edge/boundary of the universe may sound like a simple question but I can see 3 possibilities.
1 Observed, this puts us inside a sphere looking out towards an edge which is beyond visible range, some estimates appear to give up to around 50 bly away.
2 Expanding universe theory, a timeline of expansion clearly puts us on the edge of an expanding sphere looking inwards.
3 The no edge scenario
1 and 2 are opposites, 3 could fit in with 1 if the universe was infinitely old and large.
So which one is correct or is it possible to merge them all together
