Rapture

I think you're opinion is saaaaack!

Best argument ever.

A floating city would be preferable, it's unlikely that the entire planet will ever be in such a state of disrepair that no point on it would be unsuitable for human habitation above the surface of the ocean. Most of the ocean's biosphere (food) is limited to the uppermost levels as well.

If the planet gets too hot, sail it towards the poles, which would be more temperate. Too cold? Migrate towards the equator. Picture vast open spaces inside, simulating the various environments, we could preserve all life in the hopes that the planet may one day recover.

It's been thought up be futurists in the past, they envision large, hexagonal, interlocking city blocks on floats that can reconfigure themselves if needed.





A city on the surface would probably be easier to maintain too, wouldn't have to deal with the same level of compression as underwater. Solar power, in conjunction with hydroelectric, wind and maybe even geothermal if you could get it close enough to a volcanic area. Nuclear power too. If the air outside isn't suitable for breathing, you could always cover the surface of this city in a transparent bubble, or find other means to purify the air. A combination of various city types would probably be the best route to take in such a situation, though it's not likely that a large portion of our population will be able to find refuge in them, given the limited space and lack of resources.

Well, if we're going with cool floating cities of the past, we can't negelect to consider Pykrete in the design.

And
Airships have always been cool, just food and water that becomes a problem.

The problem with a city on the surface is that if it's too large, bad weather would really seriously effect it. It would either have to be solidly connected with the sea floor and deal with flooding or be free floating and deal with bad shit.

I feel like there are ways to overcome this. A roof could help deal with hurricanes, and if the city was big enough what could threaten it? Harsh conditions? Bring up the walls a little to keep shit out. Storm Surge? A serious problem, but the city could be build to flow with it or ignore it, sure it won't just shrug it off but it's hardly like we shrug it off now anyway.

Of course, if we are dealing with the Rapture then the weather could get really bad. But i find it unlikely that all land everywhere can be covered with water, there simply isn't that much water available.

So in the event that Space Lord Pheonix decided to magically wizard everyone away into a magical land where all the good people of the world go to live for eternity with the being that created everything that was, is, and ever was in the entire universe - your problem is that there isn't enough water to fill the world?


That's the straw there?

So the water is being created through magic? I figured that the people were being vanished through magic to magic, not that the entire world was going to end because the laws of physics were fucked.

If the laws of physics are going to be fucked, then a floating city won't help: nothing will.

Just don't have it in a place with hurricanes, the Indian Ocean is supposed to be calm, and it goes from the equator to Antarctica.

Obviously, it wouldn't be one large solid structure, but rather dozens of smaller interlocking sections connected to each other. Imagine roping 6 container ships end in a hexagonal ring to end to make one section, that way it's not fixed in shape, but in total the whole configuration is probably more stable in bad weather than individual ships.

I find it hard to accept the hazards of a floating city exceed the hazards of an underwater city.

Opinion is still sack FYI

I seem to recall some unrest in the Indian ocean a few years back...



Mind you, an underwater city doesn't seem any more viable.

Tsunami's aren't really that big or bad in the open ocean, only when they get close to shore is when they propagate:

Tsunami can be generated when the sea floor abruptly deforms and vertically displaces the overlying water. Tectonic earthquakes are a particular kind of earthquake that are associated with the Earth's crustal deformation; when these earthquakes occur beneath the sea, the water above the deformed area is displaced from its equilibrium position.[19] More specifically, a tsunami can be generated when thrust faults associated with convergent or destructive plate boundaries move abruptly, resulting in water displacement, owing to the vertical component of movement involved. Movement on normal faults will also cause displacement of the seabed, but the size of the largest of such events is normally too small to give rise to a significant tsunami.

Tsunamis have a small amplitude (wave height) offshore, and a very long wavelength (often hundreds of kilometers long, whereas normal ocean waves have a wavelength of only 30 or 40 metres),[20] which is why they generally pass unnoticed at sea, forming only a slight swell usually about 300 millimetres (12 in) above the normal sea surface. They grow in height when they reach shallower water, in a wave shoaling process described below. A tsunami can occur in any tidal state and even at low tide can still inundate coastal areas.

That picture, kinda looks a little shopped too. Was it really that tall?

An underwater city would probably be equally unaffected by a tsunami, if it's sufficiently far enough away from the shoreline. The thing is, if you anchor it to the sea floor, then it would be affected by earthquakes like above ground cities, unless maybe you put suspension in whatever anchoring mechanism used. It seems like over kill compared to what is essentially a large boat, or several large boats tied together. Probably the safest place to be during a tsunami is floating on the open ocean far away from land.
