Hi
I'm just wondering how other life forms on different planets might be able to evolve. Some of my thoughts:
1) other life forms don't necessarily need oxygen do they? On this planet we use oxygen to generate energy through combustion. Other life forms could generate energy by
i) combustion in another gas e.g. fluorine?
ii) something different to combustion altogether though I'm not sure what. I can't remember enough about things like electron transport chains to know if they need oxygen
2) could simple life forms exist that weren't carbon carbon based? Silanes can form polymers up to 10 units long if i remember correctly. Could you have silicon based life?
Any thoughts welcomed
