Besides Human emotions, seeing past tachyon-interferrence and most forms of empathy, what is Manhattan not capable of?

He can either create matter from nothing or create instant nuclear fusion to ”create” essentially anything. He can fly, replicate himself, destroy people on a fundamental level, show people visions, share and pass on his abilities, create and destroy parts of reality itself, kickstart universes, see almost any event in time and space, instantly, or practically instantly, teleport himself, move at possibly infinite speeds without destroying earth and the universe, destroy eart or the universe with little to no ”effort”. He doesn’t need sleep, water, food or air. He never tires, has immesurable strength and is potentially the most powerful being in the comics, excepting other beings on his level of outerverse and beyond

So, what can he not do, or not do by doing something else and causing that to happen? Like seeing someone else’s future to see what will happen to their future partner whom he hasn’t met
