Yeah, sounds fun. I think I will add Ethyne (Acetylene), along with Phosphine (Jupiter has it) into the atmosphere. It is starting to get interesting - I was having a hard time finding such gases which are in fact gases at the temperature I want.

Thanks very much. That makes a lot more sense Yes, I have already looked into the gravity aspect and have an idea of what the atmospheric pressure would be with methane and ethane. I have a much better idea what to look for now; thanks.

Wow, thank you very much for all the info. I must say however, that it is a little overwhelming for me. I even showed it to my chemistry teacher and she didn't understand some of it either. Would you know of any simpler explanations (please)? If this continues to evade me, I probably will make up my own version of fire using different materials and effects - should prove interesting. Anyway, thanks for all the effort you have put in so far; at least I know that it can potentially be done.

So far, I have researched a lot and come up with a fair amount. The theory behind the whole plot is immense. I have so far decided on the respiration of the inhabitants which involves methane, ethane, an organic liquid compound and an equivalent to glucose. The symbolic reaction suprisingly works and so in theory, does work. I have actually already looked into fluorine and chlorine. I have determined that at the temperature the planet is, chlorine would be in its solid state and I am advised that fluorine is not too responsible to have in the atmosphere in large amounts. Anyway, thanks. Hmm... I don't remember putting this in the homework section. It was supposed to be under the chemistry section. Oh well.

Thank you very much for the quick reply. I finally have an answer i've looked so long for. Funny isn't it? Hours of trawling the internet comes up with nothing and then just 10 minutes waiting for your reply gives me one. Sods law.

Hi, I'm Matt from Milton Keynes, England I am currently 16 and want to be a vet. I am a great believer in science and enjoy every aspect of it Hopefully joining these forums will help expand my knowledge of the scientific world and make some new friends I have already learnt about Adamantium from one thread So.... hi

Hi, This is my first time posting so... hi Anyway, I have a question (which you may have guessed). I am writing a book/story which is about life on another planet and i am trying to keep it as scientifically accurate as possible. One thing which i need to know is; Is there any gas which is combustible in an atmosphere with no oxygen? Or even any substance? I'm pretty sure you will all say that all combustion is, is the rather hot, oxidising reaction which we see as a flame. My question is really asking however, if there was an atmosphere with no conventional earthly fire, could something at least resemble it or would i have to create something? I have to stay away from oxygen as much in its elemental form because it would conflict with far too much else in the story. Thanks very much Matt, 16
