Uluru is one red rock in the middle of a desert
Mark Uluru on a map and the first thing you notice is the blank around it. Then you see the single red rock in the middle. The line "one red rock in the middle of a desert" does not mean the subject is small. It means the outline of a thing only appears once you take the surroundings away.
Cities are usually described alongside other cities. Uluru is the opposite: its surroundings have withdrawn into the distance. The coordinates the app holds for the destination are -25.3444, 131.0369. The more you zoom into this one point, the less the screen shows you more information and the more it shows you the wide space around a point. It is also why the itinerary does not suddenly get dense after an imaginary journey arrives.
A great circle running south out of Seoul
The great circle distance from Seoul to Uluru is 7,008 km, on a bearing of south. On a flat world map it looks like a straight drop southward, but the line you get by unfolding a shortest path across a sphere depends on the projection on screen. The empty space visible on the map does not mean nothing is moving. It means a distance not chopped up by city names.
The sequence of airspace the service displays is South Korea → Indonesia → Australia. It passes over three countries, though the area the sea occupies on screen may register more strongly than the list of countries does. The fewer nameable points between origin and destination, the more you have to look at latitude and longitude rather than at cities to understand where a place is.
A blank called 8.7 hours
Assuming a cruising speed of 850km/h plus half an hour of ground travel, the estimate is about 8.7 hours. It does not mean a real flight time or a connection; it converts 7,008 km into the scale of a human day. Saying you leave in the morning and arrive in the evening is not enough. Inside that gap sits an entire long stretch between one city and the next.
Uluru's antipode is 25.3, -49.0, and it is the middle of the ocean (no land). At one end there is a single point in the middle of a desert; at the other, sea with no land in it. Working out the far side of the planet is less about adding a destination than about confirming a destination's isolation numerically.
Near waypoints on the way to somewhere far
The first line of the candidate list heading for Uluru is, unexpectedly, Dalian: 493km from Seoul, detour ratio 1.10. Fukuoka is 540km / 1.01, Nagasaki 597km / 1.01 and Hiroshima 606km / 1.03. Not cities near the destination, but cities near the origin that do not stretch the overall line by much.
Qingdao is 610km / 1.07, Beppu 627km / 1.02, Matsuyama 667km / 1.03 and Takamatsu 730km / 1.05. Going by the numbers alone the road looks densely marked, and yet after passing all of those cities, the wide southern blank is still there at the end. Waypoints do not remove the blank. They only mark, briefly, how far you have come.
Write Uluru down in one sentence and it comes back to a single red rock. That sentence lasts not because it is insufficient but because it is exact. Cross 7,008 km from Seoul, pass over Indonesia and Australia, take several close waypoints on the way, and the final frame still shows one point together with a wide margin. Some places are remembered for showing you a great deal, and some for the emptiness around them.
