Hi! So...as you can see from the title,I'm having a problem with an alien planet in a story I'm creating,but not one you'd think would be: The planet harbours boron-nitrogen-based life with ammonia as a solvent.The only problem in this is: Boron is scarce.So,I need help in terms of making up a plausible reason for boron to exist in large quantities on that planet.I read somewhere(can't remember where) that "this problem can be largely solved by star systems with increased levels of cosmic ray spallation." Can someone explain what does this exactly mean? Yes,I have searched it up,and,unfortunately,since English isn't my first language,Wikipedia wasn't kind to me with all of its complex terms! So,any help would be greatly appreciated! Oh -- and,that being said -- it would be of great help if you could give me your opinion on two questions I'd like to ask you! -The planet being cold(for obvious reasons) and dark(but not entirely dark) -- how do you think that would influence the senses of the living beings on the planet? I'm also planning the planet to have one intelligent alien civilization,so how do you think the environment would influence them too? -Which element do you think would be most plausible as an alternative to oxygen on the planet? That's all,thanks guys.
