Well, chronologically past you I suppose, but I happened to read your comment first myself - so he was future you to me despite knowing he was logically past you posting previously.
If time travel was possible, wouldnt we already know about it?

You'd know because the universe would a place in which there is no single clear arrow of time; we'd be used to the notion of effect preceeding cause for instance.
It would all depend what theoretical view of the universe you hold. If you held the Multiverse theory of the universe then you could travel back in the time, change something and simply create a new branch of time. Your original timeline would remain the same and absolutely nothing in it would be different from your voyage back. If you hold a single linear view of time than you going back would create a new branch, the old would be destroyed, and so would you preventing you from actually going back in the first place, thus nothing changes.

You're constrained by the universe you're in, the geometry of THAT universe. If this universe simply doesn't allow (read: lacks the necessary curvature) travel into the past, then you won't be accessing another universe. In a realistic study of multiverse theories, they're still fundamentally isolated from one another, except in an infinite inflationary model, in which case they are almost entirely isolated MOST of the time.
