B From where is the universe expanding?

[Odette]

Is it expanding from the edges?
Or from the center?

 

[Orodruin]

As far as we can tell there is no center nor any edges. The expansion is an intrinsic increase in distances between objects.

 

[Odette]

As far as we can tell there is no center nor any edges.

[Orodruin]

At all.
