We've all seen Inversia now and then. You look at a map and mistake land for sea, sea for land. It happens most often with those crisp, simplified news maps ("just the facts, ma'am!") showing a place you don't know well. As Orwell said, "ignorance is strength." But Inversia can sneak up on you, too. I once saw a whole antique globe inverted--for the oceans' ink had aged over the years from blue to a strange sepia that I saw it as dirt; and those the original brown of the continents had faded to white; I saw them as shallow seas.
What if they were? The Sahara Sea, the American Ocean, the Himalayan Trench...
Inversia can't be a simple swap of water and land. Paradoxes rise. Picture a deepsea atoll that barely breaks the surface; inverted, it becomes a deep pit in a highland. Obviously it'll fill and become a lake--but how deep, how big? What are the odds it'll fill to exactly match its flyspeck shoreline on Earth? In rainy regions the lake will grow way beyond that, until it spills over; in a dry zone the lake will be smaller (and salty).
In general, I've stuck to the familiar shorelines of continents and large islands--New Zealand, New Guinea. You need some signposts! But I've let smaller islands-become-lakes, like the Hawaiian chain, fill to whatever size and shape seems right for the local rainfall (which of course these inland seas affect! Which came first, the chicken or the egg?)
What of the reverse--Earth lakes? Should they be islands? My conclusion: not all of them. Only where a Terran lakebed dips below sealevel (not easy to determine in most atlases, but I've done my best) did I build islands: see Lakes Superior, Baikal, Tanganyika, etc. This makes the shores of the new Baikal Islands consistent with the offshore terrain; if I honored the Earth shoreline above sea level, we'd get huge, geologically senseless cliffs right at the waterline.
What of lakes or seas BELOW sea level? The Inversian island of Caspia is larger than our Caspian Sea, for that basin is well below Earth's main sea level, the largest such region on Earth; and Caspia's coast follows sea level. The dying Aral Sea makes an equally shrunken Inversian island, but not due to its current drought problems: its bed is shallow, so only the deepest part dips below sea level--making a small island on Inversia.
There are a few Inversian islands where Earth has no water--just a dry valley below sea level, as in Egypt, California, Tunisia, Israel/Jordan, Ethiopia, and Sinkiang. All deserts, of course--elsewhere they'd be lakes. Well, not quite all. I forgot Greenland and Antarctica. On Earth, their hearts are depressed by ice to well below sea level; so Inversia has a Greenland Sea where our coastal mountains lie, but it's a mere moat; inside it is a modest but truly green Greenland. The new Antarctic Ocean also has unexpected land at its heart.
In short, Inversia's a reversal of altitude not water. But even that isn't so simple. I quickly found that supposedly authoritative sources disagreed on even basic seafloor topography! The southeast Pacific was especially hard, for it has not one speck of land; most globes and atlases use it as a place to put their legends and logos; even if they don't, undersea features are sloppily shown. There are plenty of errors on Inversia, but even if your atlas shows me to be wrong... don't trust your atlas too much. Even the detailed maps I finally used (thanks to SF State's map room and the online General Bathymetric Chart of the Oceans, GEBCO) firmly disagreed about names, depths, topography, even reefs--as close to land as the region gets. It was a real cartography lesson: wherever they figure no one will look closely or care, even modern maps get sloppy.
I've generally gone with the principle that where there's smoke there's fire: if even one reputable map recorded a reef or trench others lacked, I included it. Where they disagreed (i.e., everywhere!) I made judgment calls. I can't claim great accuracy or even consistency--but then, the whole project is insane, of course.
For comparison, I'm working on a variant Inversia: remove all water, invert, ending with the exact same "dry" topography as Inversia... but then pouring all our Earth's water back onto it. The result? Utterly alien coastlines. The only land is the deepest bits of our oceans--the abysses and trenches. Call it Abyssia. It's hard to calculate the volume of those inverted sea basins, but they're deep. Shocked me just how much high the flood went. Less than half the land area of Earth! Brings home just how much water Earth has. A bit more, and we'd have a world-sea. I've nearly finished Abyssia, but then it has so little land it's quick to map! Paddling in the baby pool until I learn to swim.
In contrast, Inversia has 2.3 times as much land as Earth, over five times as much as Abyssia. I'm roughing in the American Oceans now; it'll be some time before regional tours appear.
Once we're sure what's land and water, the next step is climate. This gets complicated, for the new, radically different topography changes the air pressure. Nearly all of Earth is near sea level; Tibets are rare and there are no big holes like Hellas on Mars (air pressure twice Mars-normal). But Inversia has small, deep lowlands and huge highlands--many Hellases. Now, you humanities majors will just have to trust me, but this odd topography means air pools and gets dense down in the new basins: air pressure at the new "sea level" is 1.7 times ours!
Ecologically, too, it's a riddle. The deep basins are unlike any ecology on Earth today--hotter and wetter than our densest rainforests. That dense air traps heat and transports more moisture. But how much rain from these steamy, alien basins climbs up the huge new continental shelves? Our nearest analogy, the altiplano above the Amazon basin, is dry; but Inversia's air is much denser. This question of rain-transport is vital, for it decides how much of the vast uplands will be desert. How much Carboniferous, how much prairie, how much Mars?
My own projections are undoubtedly wrong. Climatology at this point's an infant science; it's all still educated guessing. But how wrong, where, in what directions? Cool uplands, hot wet basins, these I'm sure about--but beyond that?
Is Inversia more or less fertile than Earth? Smaller seas means less rain. Wide inland deserts! But then, much of our deep sea is desert now, judging by its biomass. Sediment and upwelling currents, the two greatest sources of nutrients, are rare in the open sea. Inversia's biological deserts may just be more visible.
And even if Inversia's dry, there's a lot of it. The huge new swiss-cheese world-continent has relatively fertile coasts, and a lot more of them: where our oceans have mid-sea ridges and seamount chains, Inversia has inland seas bigger than the Mediterranean. Even a modest island in our world is just the tip of a much broader platform; on Inversia, this often translates into a huge, deep high-altitude lake. Millions of square kilometers of surface water from these inland seas generate rains that moderate the climate of these wide Inversian uplands. This isn't Pangea, that ancient supercontinent with green coasts but a super-Sahara at its heart. This is something new. Land and water mingle bewilderingly--deserts exist, but they're patchy.
One reason so much of the new land is dry: lots of the new coasts have tall mountains--wherever offshore trenches lay in our world. Such ranges cut off rain to the interior plateaus. Pacifica will especially suffer. Expect wide steppes at best, deserts at worst.
Shallow waters are generally more fertile than deep ones; minerals are more accessible, and most of the biological action's in the sunlit part. Inversia's seas are warm and shallow; they average just 600 m (2000') deep, vast stretches are 100 m or less, and the water's mostly warm, insulated by denser air. Ideal for coral reefs! Even in deeper regions, our river valleys invert into sinuous ridges, forcing currents to wash over them--and as they do, great rolling plumes of sludge approach the surface, feeding plankton. Such ridges are also excellent seedbeds for coral reefs. Even the deeps mostly aren't THAT deep, and are largely coastal--often, on Earth, more fertile than mid-sea deeps. Inversia's land may be heaven or hell, but the seas are unambiguously rich.
Will intelligent life evolve? If so, where, and what kind? Even in our world, with its extinctions and migration barriers, big-brained primates are scattered over a hemisphere--orangutans live in Indonesia. On Inversia, where you can walk around the world, primate niches may actually expand. And not only primates. It's worth remembering that (even restricting ourselves to land animals) elephant brains are as complex as ours, while Arctic wolves have chimp-sized brains, and bears aren't far behind. Parrots and ravens have recently proven to rival apes in intelligence. Inversia, like our present world, will have a rich pool of intelligent creatures, the right environment to shape them, and plenty of time.
Are there any generalizations we can make about the Inversians? Just that they won't be us. And not just superficially so: not just physically and genetically different, but in basic temperament. Aggression, territoriality, sociability, gender differentiation? And subtler traits: the social finesse of bonobos, or the political cunning of chimps, or the shy tool-cleverness of orangutans? And these are just differences in our immediate family! Postulate super-parrots, mini-elephants or amphibious cetaceans and the dominant sense may be not be sight, but smell, touch or hearing. Is the sense of self different in sonar-using species, where soundfields sweep through you all the time, where the state of your stomach is a public affair? Do folks like that even have a word for lying? Or in smell-centered species, where everyone knows whether you're in estrus, will sex be public? Such species differences will shape nonhuman cultures profoundly. Look how we take our tool-dexterity, our intraspecies aggression, our constant sexuality, and our smell-blindness (and consequent ease of lying) for granted! Civilization is not one-size-fits-all.
My picture of Inversian culture is still hazy. One certainty: the low coasts around the ex-lands will be very different from the raised seafloors. The high air pressure in these low basins (nearly twice what we're used to; four times as much, if you're Bolivian) will let much larger animals fly. Indeed I'd expect most life in these basins to be winged one way or another--including intelligent life.
A winged civilization will be very different from a ground-based one. Politically and culturally unified, with fast communication but limited trade (because who wants to poke along with cargo on the ground or on the water at one-tenth speed?). Production will tend to be local, but news, ideas, culture and inventions anywhere in the world's basins will spread with lightning speed--indeed this single factor may guarantee that the sea-basins dominate world culture and technology. A winged Web.
The uplands? Hard to say. In general, Atlantis and Indiana will be like mile-high plateaus on Earth, but Pacifica is higher--the northwest, 6 km above sea level (20,000') is nearly Tibetan. Still, Tibet is warmer than isolated peaks of the same height, and NW Pacifica is far bigger than Tibet, with slightly denser air, about the equivalent of Earth at 3 km (10,000'). So even these heights won't be utterly barren and certainly won't ice over. But these huge, thin-aired plateaus will be unfriendly for giant parrots from the sea-basins; they may even be grounded. Who'd settle land that takes away your chief joy? Settlers can plant trees, irrigate crops, build railroads... but you can't reform the air. Would you renounce flight?
So I think wingless people of some form will dominate the uplands, as on Earth. Here, the fastest, easiest transport will by ship. In the uplands, great oases like the Hawaiian Ocean will become giant Mediterraneans where sea-trade fosters local civilizations ("local" as in Europe-sized). There are half a dozen of these super-Mediterraneans; they alone could support a population and cultural diversity comparable to all Earth. Around these diverse but all civilized oases will be huge hinterlands: steppe and desert where (before the invention of railroads, at least) goods and ideas must spread slowly, by caravan.
To sum up: Inversia is two worlds in one. So it's less likely a single people will dominate, as on Earth. Even if technology has some inherent tendency to become the monopoly of the first critter to invent it--and I'm skeptical that we can generalize from our single example--Inversia's lowlands encourage flight and the uplands discourage it. There may be more than two intelligent species, but there certainly won't be less.
Will they cooperate? Yes. That's the one thing I can assert flatly. Why? If they didn't, if one (probably the basin people, with their faster communication) tried to dominate the uplands the way Europe tried to colonize the whole world... well, Europeans overseas might die of tropical diseases, but they weren't instantly and universally crippled simply by leaving Europe! In contrast, Inversian lowlanders will be helpless in the uplands. The locals have overwhelming advantages in transport and communication. A Conquistadorean techno-edge might win you a battle or two, but you couldn't settle the territory.
The Conquest does suggest an exception: the silver mines of Potosí, where generations of Andeans mined for European rulers who could barely breathe at that altitude. So yes, Inversia's lowlanders might be able to hold a few key, lucrative points--mines or vital passes. But wholesale conquest or colonization is biologically impractical. Inversia discourages empire; trade makes more sense.
Of course I'd say that's true on Earth too. And look at us.
AN INVERSIAN PARALLEL
In 2009 I got a complimentary copy of Frank Jacob's Strange Maps (because I contributed maps of Dubia). It's a very funny book of... oh, take a guess! To my surprise and amusement, the cover of Strange Maps is a elegant, simplified world map by Vladislav Gerasimov (vladstudio.com) of Inverted Earth--yes, it's even called that. Parallels all over, right down to the Great Islands and Baikal Island.
Just wanted you to know my Inversia wasn't inspired by Vlad's work (I started it long before) but the inevitable result of applying the same logic. I can't aspire to his stylishness; my focus will be on working out the details of this vast world that inversion exposes.
THE RANDOMIAN FACTOR
So. A vast world full of intelligent life, not a super-Pangean desert one might, on first glance, expect. Does Inversia look too damn nice? Unrealistic? Beware--there's a hidden factor making well-informed readers expect the worst from any radically altered world--not just Inversia.
"The grass always looks greener on the other side of the fence." That old proverb isn't about jealousy, as most people think. It's subtler than that. You see, it's literally true. When you look at grass you stand on, you're looking down--you see the leaves end-on, so a lot of bare earth is visible too. When you look over the fence at your neighbor's grass, you see it full-length, at a low angle, so the grass-blades overlap and hide the ground. Even if your lawns are identical, your neighbor's grass really does look greener.
And this effect crops up in other places. Ever notice, on a large busy road, how you always get stuck in the slowest lane? Lady Luck isn't out to get you--by definition the most crowded lane will have the most people in it! Clear, fast-moving lanes have fewer drivers. More often than not, you really ARE in a worse-than-average lane. The grass is greener in the other lanes--till you move over, and slow them up!
This principle applies to alternate earths--but in reverse.
Let's contemplate Randomia, an Earth no better or worse than ours, with roughly the same biomass, same amount of arable land, about the same population... just re-distributed. Now, what regions will you notice the most? First, your home, of course, and then, other well-known regions--and well-known means inhabited.
Randomia will always look inferior! For, by definition, most readers will be from our world's high-population zones. Random changes will, on average, degrade them. And the lands that improve, that become the heartlands of Randomia's civilizations, are likely to be barren obscure lands in our world, mere names (if that) to non-Randomian readers. The great European cities are all flooded on Inversia (millions of European readers groan), while the green Sahara nurtures great civilizations (a handful of Saharan readers cheer). If you love civilization, Randomia will probably kill or cripple the ones you love, and plant its greatest civilizations in places you associate with backwardness.
So the grass always looks browner in a parallel world--because what you value most, what you KNOW to value, is generally lost. This principle makes it hard to see alternate worlds fairly.
So, if I seem foolishly optimistic about the alternate Earths I build, postulating island leagues and tropical civilizations and oases in Martian deserts and islands in the Great Flood and seal-holes in the Global Icecube, if I postulate intelligent lemurs or elephants or mega-ravens... just remember I'm fighting the Randomian factor. Your view is colored by the degradation of what you know and love; so my predictions of new growth in unlikely regions and species, will seem fatuous. Yet they grow from the same changes as the doom and gloom--your perceptions are naturally tilted toward seeing the losses.
Factor Randomia in, before you mock.
I'm building a companion to Inversia: Siphonia. Its premise is simpler but equally drastic: drop a hose 5 km down (16,000') in the northern Pacific, and suck the oceans up til the hose runs dry. Nine-tenths of our water, gone. Now wait 100,000 years and see how life's adjusted!
The new sea level varies around the world--the Sea of Japan, being nearly landlocked, dropped very little, while the Mediterranean and Caribbean dropped 1-2 km (3-7000'), the Atlantic and Indian Oceans are now a chain of seas 4 km (13,000') down, and the North and South Pacific (now two separate seas) are 5 km down (16,000'). The old continents are generally alpine or Tibetan; most of the livable land is now in the abyss. And those lands are rugged, spectacular, and bizarre--the secret face of Earth.
