I have read the Akallabeth, and after the destruction of Numenor, the lands of the Blessed Realm are cut off forever from mortals, and if they sail into the west, they will come back right to where they started, meaning the earth is round. How do the elves get to the Blessed Realm, if the B.R. is a physical place on the earth? Do they go on a special hidden path that only immortals can go on? I mean, if the B.R. is there, in the West, how can they get to it, if the world is cut off from the B.R., and they would go in circles and never hit it?
