Well we know that the pockets of electromagnetic energy on the island causes mind boggling feats such as time travel. So what if it can cause inter dimenional travel as well, for example when Juliet detonated the hydrogen bomb. The explosion could have travelled via the build up of the energy occurring at the Swan into the alternate timeline destroying that island and sinking it to the bottom of the ocean. And the same build up of energy could have been what returned our losties to 2007.
