@Kunica - I don't think you understood what I said. The stones don't react to each other because of them being close together (not that we've seen, at least), I'm agreeing with you on that.. That's not the reason for separating them.

They didn't keep more than one stone in a single location because, if someone like Thanos were to break into and steal them, they'd be all the more powerful by having multiple stones taken from the one location, as opposed to a single stone being kept. They spread them around and shuffle locations to keep the stones harder to collect, otherwise anyone could get all 6 of them easily.

That's why Bor hid the Aether initially, to make it difficult to obtain by others.
