+Oltux72 he/him Posted March 5, 2022 Posted March 5, 2022 We do not know how extensive the spore oceans of Glorf's world are. But they do pose an interesting challenge in terms of physics. So let's make a list. Albedo This signifies the ability of an object to reflect light. Obviously a bright object is better at that than a dark or even black object. And this is a problem. One of the moons produces black spores. We are looking at a black spot at equatorial latitudes of an extent of at least a few hundred kilometers. If you sail that sea at day time, you'll be backed. And there will be severe winds. Hot air goes up and coller air is sucked in. Clouds The oceans are dry. They do not evaporate much water. Clouds that lose their water as rain will not be replenished. Lands and islands surrounded by a spore ocean will see less rainfall. And less cloud cover will worsen the albedo effect. The lands north and south of the Midnight Sea will be deserts when that dry air comes down again. Heat transport Here we are entering unknown territory. On our planet the higher latitudes are often warmed by warm ocean currents. These transports are likely less efficient on a world with dry oceans. Do we have an oceanographer or meteorologist under us? Storms Tropical storms are generally generated over warm, wet oceans. They will not form without evaporation. This will lessen transport of materials and species. Any other effects? Should I keep updating this? 1

The lands north and south of the Midnight Sea will be deserts when that dry air comes down again. Clouds also contribute significantly to albedo... That means a positive feedback loop. But, also, do we know if it even rains? That would be highly dangerous. I suppose the clouds could be made of spores or the moons could act as clouds do by reflecting sunlight. 4 minutes ago, Oltux72 said: Heat transport Here we are entering unknown territory.

Do we have an oceanographer or meteorologist under us? Water has a really high heat capacity. If the spore-fluid is not water, we could be looking at hot fluids, which might behave oddly. 4 minutes ago, Oltux72 said: Storms Tropical storms are generally generated over warm, wet oceans.

Tide This dry ocean also, shouldn't have a tide if all of the moons are stationary. So is the different colors of spores and convection currents that are causing this to behave more like a fluid ocean and less like a sand pit?

They have conventional agriculture outside Diggen's point. I cannot see how that would be possible without rain. 12 minutes ago, Kandrafish said: Water has a really high heat capacity.

No data at all. 12 minutes ago, Kandrafish said: Tide This dry ocean also, shouldn't have a tide if all of the moons are stationary. Solar tides. And yes, there should be no lunar tides, but there would be none, even if the oceans were wet.

I cannot see how that would be possible without rain. \I still wonder if it is not going to be rain on this planet, or if there is, it is going to be a weird, or very rare. I am contemplating a couple options. 1) underground water supplied by geysers or something similar. 2) glaciers, which are mined for water and transported to islands. Water comes from a "deep aquifer" on Diggins point. What if it is the same everywhere? Although, suppose it does rain, that violent agitation of the spores could cause the ocean currents, like a domino effect... Quote Solar tides. And yes, there should be no lunar tides, but there would be none, even if the oceans were wet. Ok, here is my other thought. 1) That is much weaker, depending on the sun's size, I guess. So, we need something else. So... 2) The color of the spores should create some really weird convection currents, that, I think, would override the tides. So we end up with really weird ocean currents that are affected by light from a far off sun being absorbed by different colored dead and alive spores!

cometaryorbit Posted March 5, 2022 Posted March 5, 2022 I'm not sure we can rule out the spore oceans being a relatively small part of the planet. If the moons are apparently stationary and in a geosynchronous orbit, they must be over the equator; so there might be twelve relatively small spore-oceans on the equator, with regular water oceans in the temperate and polar latitudes.
teknopathetic he/him Posted March 6, 2022 Posted March 6, 2022 (edited) The story mentions whales, so either there are oceans somewhere or something very odd is going on with noun-reference in this story. Edited March 6, 2022 by teknopathetic
Humble_Knight Posted March 7, 2022 Posted March 7, 2022 Isn't there also the global heating of millions to trillions of particles falling through a breathable atmosphere? Even if investiture keeps the spores from combusting, the atmosphere would heat from the air being pushed out of the way of the spores
