I said I had read a culture book right? Most of the races, the aliens in it, were human. They justified that by the idea that in most habitable worlds our shape, design, is still rather good, we can walk, maintain balance, interact very dextrously, we can imagine, communicate, coordinate, yadda yadda yadda. I don't normally buy into explanations, but this seemed to work, like even when I saw the star trek films I didn't get why all these aliens looked so human. They could be like offshoots maybe, colonies cut off and changed culture and a few features, but not entirely different species.
Anyway, I had a couple of scifi-ish ideas, and I didn't want to write a good explanation in word, so I decided to do this.
Firstly, Dandelions. A culture that grows, and regularly sends dozens of pods out to explore. These pods have a couple of old people, viewed as dead for their age, who can test a planet they land on's suitability and establish a beacon, as all of these pods are teleported randomly, hope they hit a planet, and hope the planet is habitable. If its habitable They begin setting up and make a beacon of sorts, so that the original culture will one day send actual ships of more people to establish a colony there. So basically, like a dandelion scattering seeds that move randomly, and some might grow into more dandelions.
Second one, Twins. Right, so what if the moon was almost another earth. A bit further away, maybe not even orbitting us, but what if a planet we could see decently had other people on it, and when you saw it you saw like the spots of light from their cities and so on like how earth looks from space? Imagine that, these two worlds who have been in one another skies for all this time, and they finally get the technogology, radio or primitive space travel, and these two peoples seperated by space finally meet. Space-neighbours, or twins almost. You could look up, and see their world from above. I think that sounds cool myself, even stranger if they have a tech-gap. I mean, even here compare the majority of one country in Europe to some parts of Africa and theres a difference, imagine if space men arrived in the dark ages of their twin planet.
Third one, Growth. You know how...this is kinda weird, even compared to what I normally do, but our bodies are built up in another body. So what if spaceships started off as infants of sorts built by other space ships, and then sent off and they grow by mining and so on, over time, rather than starting out giant they expand and are built up upon. And within those each person would be like a cell or tissue, performing roles, being replaced. The "baby" ship has the systems, but they are smaller, less advanced.
Yeaaah, just a couple of ideas, I don't know what for they were just in my head
