There is an interesting little bit about the universe in Silver Surfer Annual 2. It talks of distances from Skrull space to Kree to Earth and other things. Probably one of the first things that actually creates a "map" of sorts besides Asgard. There's also some space scale things in The Nova Corps Files with the scope of the Annihilation wave.
My subordinate Galan will be in shortly with the scans.
"A great tactician creates plans.
A good tactician recognizes the soundness of a plan presented to him.
A fair tactician must see the plan succeed before offering approval.
Those with no tactical ability at all may never understand or accept the plan.
And when a mind is too deficient in understanding, the resulting gap is often filled with resentment."
