Hi there! Firstly, thanks for giving this a read. I'm an aspiring author who's currently working on a science fiction novel. The problem is, science is not my strong suit, but I want it to be heavy on the science and light on the fiction(So to speak.). Anyway, I have lots of questions, and if anyone want's to answer them, I'd be much obliged. I had some questions answered years ago by some wonderful people on this site, but now I've started writing again and I have more!!! Anyway, I'll list off any questions I have, and if you feel like helping, awesome! If not, thanks anyway, and have a nice day!! (Also, when it becomes published, anyone who helps will get their handle[Or name, if they prefer] put into the special thanks section of the book. Just fyi. ^.^ ) Oh! Also, if you think of any questions I haven't asked, but should, feel free. I'm more than open to suggestions, as long as they're constructive!! Thanks!!
First question, is there a correlation between planetary climate and gravity? I know there's a correlation between size and gravity, but what about climate?
Second question, would it be possible over 400+ years, through a combination of subtle environment changes and outright genetic modification, to create humans capable of living in much higher gravity, such as twice Earth standard?
Third question, on a massive starship, the easiest way to create artificial gravity would be centrifugal force as far as I know. Is that correct?
Fourth question, are asteroid clusters possible outside of a traditional solar system? Or would they continue on in one direction until they were drawn into the gravity of a star?
Fifth question, would it be possible to have a nuclear reactor inside of a ship completely shut down if needed, and/or jettisoned? Or would that ruin the fuel rods to shut it down?
Anyway, that's all I can think of for now, but any and all help would be appreciated!!
(Edit)
Question Six, what would theoretically be the easiest method of cloning a human if ethics restrictions were removed from scientists? Would it be stem cells or some other method?
