They have little to no presence on Earth or Mars* unlike Mercury and Venus. Do they draw power from the Sun?
They also are absent from the gas giants. Do the Vex require a rocky surface and mantle to start their invasion/conversion of a planet?
*I know the gate exists but afaik they aren’t pouring onto the surface and making an effort to permenantly occupy the planet.
Like why can't Venus, which even modern science says that we're not for the greenhouse effect on the planet it would likely be habitable/habitable-adjacent, as well as the moons of Saturn and everything, and other non-gas giants & asteroids?
Why can't frozen worlds and things like that be terraformed?
Is it theoretically possible to find a terrestrial planet of dimensions, say, 5 times the radius of the earth?
I searched and found that Gliese 581 d is the largest found, 2.3 times the radius of the earth, but I did not find whether there is a theoretical limit to the size or mass of a terrestrial planet.
Thank you very much
I'm no astrophysicist so the radiation is probably the main thing I should be concerned about, but is this physically something that's possible, or would the planet be just as hot any time of the day?
Frivolous context: >!I had recently started a new game with StgErayze's 43710633 seed and was kicking myself for not having checked the orbit sizes. Drifting 12 AU to start setting up my second planet in the type O system, I'm reading Dev Diary #3. I finally land and start setting up the power network and picking out a good spot for the export logistics stations. I'm thinking about the gameplay loop in the diary and realize I've basically regressed back to the mecha perspective! The planet is so far away it'll take forever to ship more buildings here, but that's okay, there's not too many rare resources, so this planet can just be an ore exporter. Tapping the individual nodes is a fun minigame, but also distracts from making sure that all of them are tapped before I leave. I miss having a gas giant in my main base and it hits me how orbital collectors would be ideal for exploiting a planet you don't plan on visiting often.!<
Proposal: Introduce a new building or technology to allow placing orbital collector type buildings on surface nodes.
If I had the opportunity to add it as a mod, I would make it a new building incorporating wind turbines, solar panels and a ray receiver to determine it's output speed. Orbital collectors convert much of their gathered resources into fuel, which wouldn't work for finite terrestrial nodes.
I would also add an automation option in the form of a building crossing an Interplanetary Logistics Station and a Vertical Launching Silo to accept a Carrier Vessel/Small Carrier Rocket, Terrestrial Collector and optional Space Warper. The result would select the closest untapped node of the selected type and travel there on a one way journey to install the Collector. I imagine the result to be a sort of gardener seed ship, but with warp options.
If there's a hard limit on the number of items a recipe can use, another idea would be to use a set number of Antimatter fuel rods and mine at a proportional speed while unpowered, so that the fuel lasts until the node is fully dry. Both variants would maintain the benefit of the player investing time into developing the planet's power infrastructure, while lowering the effort floor of tapping extraplanetary resource nodes.
If any modders or devs like the idea, you are welcome to it! Thanks for reading!
Would it result in fractures of the crust that create and open up caves or something along those lines?
So, I have this idea in world on which for a strange the K/Pg impact happens a million years before or for some reason it is not so devastating as to kill all the non-avian dinosaurs, so I am inspired by this post cenozoic dinosaurs, which let open the possibility of the evolution of primates even with the presence of dinosaurs, since the appearance of fruits began. This and other little but significant changes.
Here I am referring to very separate species, I know that this has happened with the different species of the homo genus as they separated throughout Africa, Asia and Europe, but I am referring to species even of different orders, something that I will explain later. So despite the improbability of the event, I am hopeful that the correct combination of events can produce a world with many "civilizations".
Then, for that reason I was thinking that during the cenozoic, the appearance of hominids and humans happens (although with several differences to us, only so called for reasons of practicality).
With other specie evolved at Australia with Zealand that did not sink and a Southamerica in which the in which Isthmus of Panama took longer to form, perhaps a million more years, but Im still open to suggestions in which sapients could start. I have not decided the other two species yet, but I think Australia will be the land of the dinosaurs as it is the continent least affected by the impact of the asteroid and Africa, as I mentioned, is the cradle of the human, the South American species is the most difficult to choose.
So, this looks easy to find out at first, because humans have direct land bridges to Asia and then Europe, with which their expansion would be ahead of the others, but due to the presence of many more dangerous species they would remain very limited to Africa for a longer time, the same in South America, at least until they can learn to make boats and cross more easily to North America, which by the way would be the "safest" continent since dinosaurs are almost completely extinct there. While in Australia there is not much abundance, but they would have a second land mass right next to which to navigate, in addition to island chains to Asia. So I think that these species would prefer to have a more complete domain in their region than to expand, but according to information that I remember reading about why the first civilizations were further from the equator, tending north, it is because there is a greater range of climate stab... keep reading on reddit ➡
People volunteer to get sent out to look for a new planet. The humans are in groups of 3. They are chosen and then sent out to search. 2 of them are white dudes and 1 is a black chick. I think the girl was a little older and she was a scientist or something too. She always scanned everything. They eventually land on the planet and find out there is life there. One of the guys gets shot and killed at some point. The story will switch perspectives sometimes and show the life of an alien girl who lives on the planet. She has visions the foreshadow the landing of the humans and their ship. She also becomes the leader of their tribe at some point. The creatures eat a white substance and are able to have visions of the ancestors of the planet too. The humans eventually figure out there is this old bunker with that white substance and it’s a living plant or something. There is a video of some old scientist in there too I think.
I remember a lot about the story just can’t remember what it is.
I was just reading an article about a scientist dismissing the strange radio signal detected emanating from the proxima centauri system. He said it's a one in a hundred million chance that it came from another civilization. If panspermia could explain our origin though, wouldn't it hold up that other habitable planets nearby would be the most likely candidates for civilization, imagining that they would have been seeded around the same time as earth?
Maybe one in one hundred million is right, but it seems like the same number that would be given for any habitable planet in any area of the universe. Doesn't the idea of panspermia make it slightly more likely that our closest neighbor harbors life, intelligent life? Civilization even?
I'd like to see the possibility for large terrestrial planets to use and main manufacturing areas vs the small planets. Ones the same size as the gas giants.
