Where is the edge of our universe?
As of now, undefined.
A MON AVIS: I think of extending the definition of the edge of the solar system in relation to nearest star system to the edge of a cluster/galaxy of stars in relation to the nearest cluster/galaxy, and further onto the edge of our universe, in relation to a close neighbor.
So, until and unless a neighbor-universe is detected as a whole, the edge of our universe is undefined.
An edge here is believed to be a near-null field for the effect of forces exerted by those that are nearby and around.
