A sphere has an "Edge" in the third dimension.
So we have the usual questions.

What is the topology of the universe. Is it a sphere, a torus, a mobius strip, a Klein Bottle. What is the expanding universe expanding into ?

Is space curved back upon itself due to the matter it contains?

All interesting and hard to fathom.

Yep!

One thing I'm certain of right now, you have all made the TAX forms I'm struggling with seem simpler, somehow...

Yes.
However, they could not communicate to us what they see any faster than for us to see for ourselves. Whatever communication they might use, that communication cannot fly any faster than the light they might want to tell us about!
Keep searchin',

Never said the message would get here any faster. Only that they have a front seat view. It would take 14 billion years or even longer if the edge is indeed expanding faster than light.

Since they have always been on the edge perhaps they sent the message 14 billion years ago and we just need to listen in the right spot to locate it. :)

A lecture worth watching. if anything for the amazing graphics. best viewed in expanded view.
