| Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web. While unregistered users are able to browse the forum on a basic level, registering an account provides additional forum access not visible to guests as well as the ability to join in discussions and contribute yourself!

Do you think that if people used there arms enough their arms could possibly support them if we developed flight? |

They could just push off the walls couldn't they? Unless you mean something... very large, then if they didn't bother to make tools for moving around and they survived the zero gravity I suppose there would be selection for larger paddle-like hands and/or feet. Possibly more skin stretched behind the arm pits... Or do what the space folk in All Tomorrows did... |

If that thing stops rotating, everyone dies. End of story. They won't be able to reproduce and their circulatory and muscoskeletal systems will atrophy. I also see no reason for an O'Neill cylinder to stop rotating in that fashion. And change in rotation would likely be detected and compensated for long before it becomes a problem. Flapping for propulsion in microgravity is possible... they tried it in their spare time up on the Skylab space station, but it requires a lot of energy to do...

I'm assuming the cylinder would stop rotating over a very long period of time, perhaps due to the friction created by water inside it. I'm also assuming that the cylinder's inhabitants have lost their technology the same way the tasmanians did (it's hard to keep technological advances alive in a small society...there's a higher probability of ideas dying out due to the small number of people). I'm sure birds could propel themselves fine in zero-G. Humans might start out by flying normally as the gravity lowered, and by the time the it was gone completely they'd have the wings necessary to "swim" through the air...

No, the water is rotating along with the cylinder, inside it. The only thing I can think of that could affect the rotation is things like gravity gradient torque, and even that would be very long acting as well as probably unable to effectively remove all of the angular momentum of the cylinder. However, the colony will almost certainly have a despun as well as a spun section, and a bearing between the two... it will be designed to be as frictionless as possible, but obviously it will slow the spin of the cylinder. Most colony designs also propose having two cylinders, either side-by-side or in a row, spinning in opposite directions so that they can be used to control the attitude of the station. The cylinder could contain as many as 20 million, or something like that... this is not just a small space station, but a truely gigantic structure. But the fact remains that if their technology is lost, they'll all die. It's a hydraulic society; it cannot survive without technological support. Losing artificial gravity is probably the least of their problems, if something extremely critical like temperature control or lighting fails. While a gradual decline in gravity might help adaptation to microgravity, I doubt people would fare well in any acceptable amount of time. It's a very fundamental change that no organism in the history of life on Earth has had to endure. Flapping flight is probably inefficient and too energy intensive; just pushing off stuff would probably be better. |

How about attaching ropes to the edges of the cylinder and hauling yourself around? |

Time flows like a river. Which is to say, downhill. We can tell this because everything is going downhill rapidly. It would seem prudent to be somewhere else when we reach the sea. "It is the old wound my king. It has never healed." | |

I thought so too. ![]() Did you see those suits which exert force on the body to simulate gravity? |

Oh god can we please stop posting such huuuuge pictures and instead put them in a spoiler or hide them as a link? I don't have a 3 meter wide monitor and all the posts and the text is stretched the whole width of the picture. |

Link? I'm not sure what you mean, since there are various devices that can alter or help the body to deal with gravitational force in one way or another, but I haven't heard of any suit that could provide effective artificial gravity in space. |

Looks uncomfortable and I also doubt it can simulate all the effects of gravity. |

It's designed to simulate the pressure gravity puts on the person's skeleton, that's all. |

"How about attaching ropes to the edges of the cylinder and hauling yourself around?" Only the cylinder is about 5 miles wide and twenty miles long. Remember that it stops spinning very gradually. Edited by Spugpow, Nov 9 2010, 11:12 PM.
