I'm kind of disappointed by the "magical" explanations we're getting to the mysteries. The whispers are guilty ghosts. The MIB is "evil" and he's trying to escape (still hoping that's more complex than it appears). They had never seen the lighthouse before because they "weren't looking." People in the alternate universe are getting memories from the first universe through NDEs and kissing (except Sawyer and Charlotte, who did a lot more than kiss and never once recovered any memories).
No magic was needed to link the universes together, because they're already linked by a shared history. There are a number of island survivors who remember meeting the candidates and even the Incident itself; they should be central to the alternate universe. Instead, they're arranging rock-classical fusion concerts and handing out awards.
We really need a scientist type to paint a veneer of sci-fi respectability over the island. Say we didn't see the lighthouse because the island's unique spacetime topology obscures it unless you approach it along an exact vector, or the exotic matter in the spring heals wounds by reversing entropy, or something like that. But all our scientists are dead, so all we get is Hurley's handwaving and appeals ad Iacobum.
