‘If you could access any universe, and go back to one universe at a very early, pre-sentience stage with an already highly developed civilisation…’ ‘You could take over the whole thing,’ the drone confirmed. ‘An entire universe would be yours alone. In fact, go back far enough - that is, to a small enough, early enough, just-post-singularity universe - and you could, conceivably, customise it; mould it, shape it, influence its primary characteristics. Admittedly, that sort of control may well remain in the realm of the fantastic, but it might be possible.’
