Rature and Columbia are the two cities in the Bioshock series. with our current technology is it possible to create worlds like Rapture and Columbia

discuss

Those islands and skyscrapers they built in Dubai remind me very much of Columbia/Rapture :P

@MDMAniac

only problem they r on land

@kowenicki

looking at the trailer columbia happened in 1912, just saying hypothetically speaking with what can be accomplished then can be done now.

I agree with Kowenicki for this one. There is the technology to sustain the structures something like rapture under the sea, but it would require tons of avaliable energy (so you can have not only eletricity, but breathing gas and heating so don't freeze - the depths are cold as ice but still liquid due to pressure). 

Besides our best chance to see a floating city isn't even in our planet (Venus is the most likely candidate due to it's liveable zone up 50km. Still it could definitely happen and it would be a lot like that Star Wars sky city, since it would consist on massive oxygen-nitrogen baloon [lifting gas on Venus] sitting under a city).

An underwater city? Who knows... it might be possible, though I doubt it'd be anywhere near as expansive and well-thought-out as in Bioshock. Besides that, like kowenicki said, the economic side of things would be... insane.
