Ok, obliviously I used a bad choice of words to get my point across. My point being I just get the feeling that it cheapens the idea of the Triforce to say that two different timelines exist and each one has its own Triforce. Again, my personal feelings against the split timeline theory. Or are we suggesting there is one Triforce and it exist in both timelines? And I guess I am not clear on your point about why the timelines can't interact with each other or why one would be doomed?
The Triforce could be just one Triforce interacting in two different timelines, or it could be "two" because there's two of everything else. The timelines can't interact because they were split from each other. Traveling to other worlds is one thing, but all of those worlds are in ONE Timeline. You usually can't cross over. And the Triforce is the foundation and providence of the world. The Goddesses basically left it behind to keep their creation together. The power to use it to wish for things is derived from the fact that the Triforce is basically the "program" that keeps the system/universe running. Without the Triforce, you can't have a world.
http://tvtropes.org/.../CosmicKeystone the Triforce is one of these.
Anyway, even ignoring all that, you can't just ignore something like the Split Timeline just because you personally dislike the consequences. There's evidence for it, and it's official; now one of the few timeline facts we have. You can't just ignore that because the idea of the Triforce having two different locations/incarnations displeases you.
The Sacred Realm is timeless, and thus the Triforce, or at least its magical properties, may be as well.
No it's not. Link was sealed inside the Sacred Realm for seven years, and he AGED SEVEN YEARS. Not to mention that if it was timeless, there could be no cause and effect; IE no events could happen inside it. But not only is that not the case, but time and space in the Sacred Realm matches up with Hyrule, as proven in LTTP. This timeless bullshit is a load of bunk invented by Lex and there's no evidence for it anywhere in any game.
So there's two timelines, and one Sacred Realm for both of them.
No.
but OoT specifically states that the Sacred Realm is timeless.

ALttP is a sequel to OoT and lies in the AT.
Impossible. For one thing, TP leads into LTTP and Hyrule was...you know, destroyed in TWW.
Not to mention the fact that the Deku Tree is actively trying to reverse the flood in TWW through the use of trees.
Actually, he said he was going to connect the islands and make a new lands. This doesn't require undoing the flood, and the new continent wouldn't be Hyrule anyway. King Daphnes basically wished for the destruction of Hyrule, and nothing but another wish of the Triforce or an act of the Goddesses can undo that.
