Question

Where is the edge of our universe?

Answer 1

As of now, undefined.

Explanation:

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.
