Yes. The alternate reality is something like "the world we know but turned the way we dont know", meaning that in some reality Red Skull rules the world as World Führer and HYDRA being world army. Than in each reality there are dimensions. Well, thats how I understand the "space-time reality concept". I will better dont dig too deep into this :D

Honestly, I am not sure that it is really that Aether turns matter into darkmatter, its the first thing written about its energy on this wiki. It is probably coming out from its abiltiy to convert the whole galaxy into darkness, or the Nine Realms (than Dark Elves are very restrained by their outlook on the universe). That Jane Foster was weakening when being host of Aether coems from the thign that Infintiy Stones are very potent, and only powerful beigns can wield them. Like the Orb was safely wielded only by Celestials without worried of being vvaporized (Ronan is... little different case, he put the stone to his hammer, not used it directly by his body). Jane Foster was "too weak" to cotnain Aether's power, same as Red Skull could not handle the full power of Tesseract and got teleported away, and Collector's assistant (Corina?) beign vaporized by Orb by a single touch.

About Aether's powers, it can form tendrils and tornados of itself that can be very dangerous to any lesser beigns (humans).
