One thing of note is that during an incursion, the only part of each universe that incurs into the other is Earth. The rest of the universe remains outside of the incursion area, which is why it remains hidden. As we see below, the Infinity Gauntlet doesn't function outside of it's native universe:So the only part of the incurring universe that the IG can effect is the Earth. So Cap's push can only be directed at the incurring Earth but by pushing that Earth back, he also pushes that universe back. Reed's words support this. In the same way, by holding the two Earth's apart, Hyperion similarly holds two universes apart and apparently, the Great Society does something similar possibly using something that is their equivalent of the IG.
During an incursion, Hickman treats Earth like a fixed part of the universe and explains this with the "island" analogy as opposed to the fanboy created analogy of a ball in water. 🙄
Doesn't matter as pushing back a planet stops the incursion according to GS.
