When you go to sleep tonight, Euler is gonna be under your bed.
- Euler finds out the solution
- Graph theory never gets invented
- We never have telecommunications or GPS
A problem with this is that the river presumably goes all the way around the earth. Otherwise you could just travel west until you found its end. You really need a donut shaped earth, a sphere doesn’t help much
But the river running round the whole planet does not matter in this case.
You run into it on the planet backside and then need another bridge, right?
What about an opposite bridge where you cross under the river? Some sort of tubular subterranean structure. We could call them opposite bridges.
Won’t be in Königsberg anymore though, so that bridge won’t count
this guy topologys
Is Köningsberg donut shaped?

Ahem Greetings. Can I have a go at it?
but are there an even or odd number of bridges allng the circumnavigation
yes
Crossing oceans, which are continuous with the river, seems to make this about as meaningful at tunneling under the river.
I feel that leaving Koningsberg is already breaking the rules.
No bridge, no problem!
