I’m surprised no one has mentioned the trilogy by Bob Shaw based on the idea of a double planet sharing an air bridge (“The Ragged Astronauts”, “The Wooden Spaceships” and “The Fugitive Worlds”). Eighteenth century level societies are able to cross using balloons, eventually engaging in warfare. Poisonous bubble creatures in some places. Primitive space stations made out of wooden barrels. Weirdly plausible, excellent storytelling as always with Bob Shaw. Recommended if you like this concept.

A cool idea for a scifi fantasy series would be for a man to open a portal to an alternate earth. Everything works fine, the portal is open and when he passes through he realizes something is very wrong. This is not the planet earth, and the moon is a planet. All around are dinosaurs, mammalian megafauna, mythical animals(dragons, gryphons and whatnot) and other hominids(elves, orks, dwarfs etc ). He constructs a telescope and realizes that this is in fact the solar system that he is familiar with with one slight difference. The collision betwith the primordial earth, here it is named gaia, and theia had never occured. Instead the two proto planets had started to orbit each other. The difference in gravity/tides/moonlight on the sides of the planets would make some really freaky creatures. The elves evolved where gravity would be lesser, and dwarves the exact opposite. Space whales and sentient gas bags could have a primitive biotechnological habitat in between the planets. Literal sky pirates would exist to raid said habitat.

Hi Issac, I have had this topic on my mind for a while now about mining on other planets. The formation of minable veins of various metals like copper, zinc and especially uranium here on earth is very much dependent on both active tectonics and water. An example is when plates submerge with high water content, the high pressure water is what moves magma streams upwards in this type of volcanism. Along the way as the water drops in temperature and pressure, they deposit some materials they "dissolved" from the crest and mantle. This forms minable deposits of various forms near the surface, with distinct areas of deposit for different elements. What would happen on venus, where presumbly the stagnant lid prevents continious tectonics, can these concentrated deposits still form near volcanic regions (if it had water to begin with)? Will mars have these minable deposits near the surface despite the lack of mantle activity? Potentially, predicting geology of Mars can have an impact on the direction of martian development, as if there's easilly accesible minerals it can really boost the econom early on.

on the topic of defining double planets, I once saw a video discussing the topic that pointed out the biggest flaw with using the barycenter as the defining trait between a double plant and a moon. if the moon's orbit was farther away, the Earth-Moon Barycenter would shift outside the Earth, even though the Earth-Moon system would look even less like a double planet in that case then it already does now. and if Pluto-Caron were closer togeather, making them look even more double(dwarf)-planet like, their Barycenter would shift inside of Pluto, thus disqualifying them.

There would be no super tides on such close double planets. Let me explain. The two bodies would be stretched quite a lot, that's true, but they would be tidally locked to each other, they would not be moving relative to each other, the tidal bulges would always remain in the same places on those planets surfaces. The gravitational influence of the star they orbit would probably make them wobble a little and produce _some_ tides, but nothing as spectacular as if their rotation and orbital periods were not synchronized.

If there are no tides because the same sides are always facing each other, then there would actually be less tectonic activity, right? This also begs the question: What happens to their magnetospheres if both planets are tidally locked? Do they even have them anymore? Do their cores die at a much faster pace?

The thing about a double planetary subsystem within a certain main star; tends to not last for long enough, for complex living beings to thrive a little bit; maybe into early tribal life. Because, in space, satellite physics, imply that the satellite itself, should be as light as possible; when in comparison with the then: orbited stellar object. One example for such, is the current neighbouring triple star system of Alpha Centauri. Where Alpha Centauri A and C, are as distant from each other, as Uranus, is from the Sun; due to them A.Centauri A and C, having similar mass and weight. Also with Alpha Centauri B, also known as Proxima Centauri, being just about 20% of the same mass and weight as Alpha Centauri A. Which allows P.Centauri to be enjoying its cartoons, just from the second row.
