That second scan was worded badly. Will edit.
We are our own worst editors.
Also working on the issue of that scan.
Edit: Got it,
Thor #185. The rest of the story goes from 185-188, 1966.

One thing to note about that scan, in #187, the text states that even though the distortions are happening at a range of light years that should take quite some time to be detected by Earth (because it's from the furthest reaches of the known universe, the scientists were picking up those signals instantaneously, thus defying the laws of science. It should be noted that the reason that this incarnation of Infinity took control of Odin was precisely because of his power (when her powers were severely limited) and thus was key to her scheme to destroy the universe. Even if he isn't a universe-buster, it seems getting his power would have been a major step towards attaining universe-destroying power.
From the
wiki: "Odin's power was so vast, that when a part of Odin, his dark side bonded with the conceptual entity Infinity, went rogue, it was so large that it could crush planets in its grip as if they were pebbles, his mere limbs stretched as far as galaxies. Odin's battle with Infinity destroyed entire galaxies and countless worlds. When awoken from his trance by Thor, Odin swiftly got rid of Infinity and with one simple act was powerful enough to restore all the damage Infinity had caused across the Universe in moments."
