Most scholars do agree that because the world is round, it is theoretically possible to sail west from Westeros across the [[Sunset Sea]] and eventually come around to [[Yi Ti]] in the far east, but no one has ever succeeded in the attempt. There are basically three theories as to the size of the Sunset Sea: most believe that it is an ocean so vast that no ship could ever make the entire voyage to Yi Ti without running out of supplies, while a few explorers dare hope that it is just large enough for ships to successfully complete the trip (if they can find safe passage, though none ever have). A very rare few have posed the controversial question that the Sunset Sea might be so vast that there are actually entirely new, undiscovered continents between Westeros and Yi Ti.{{ref|FAB|The Long Reign - Jaehaerys and Alysanne - Policy, Progeny, and Pain}} [[George R.

[[Alys Westhill]] and [[Eustace Hightower]]'s expedition of {{date|56}} discovered [[Aegon, Rhaenys, and Visenya (islands)|Aegon, Rhaenys, and Visenya]], three small islands in the Sunset Sea, southwest of [[Oldtown]], that are further west than the Lonely Light. While Eustace turned back to return to Westeros, Alys continued sailing west, and was never seen again.{{ref|FAB|The Long Reign - Jaehaerys and Alysanne - Policy, Progeny, and Pain}}

Lord [[Gylbert Farwynd]] of the [[Lonely Light]], the westernmost of the [[Iron Islands]], speaks of lands farther to the west, across the Sunset Sea. According to him, this land has no winter and no death. These claims are not treated seriously.{{Ref|aFfC|19}}

Maesters have heard that explorers from the [[Summer Isles]] may have mapped the western coasts of Sothoryos to the bottom of the world. The explorers also may have discovered strange lands far to the south, and west across the Sunset Sea. However, the truth of these stories is known only to the princes of the isles and their captains.{{ref|TWOIAF|Beyond the Free Cities: The Summer Isles}}
