    I've been looking into possibilities of alien biology, and their base chemicals, and cellular respiration. Arsenic replacing phosphorous in DNA, and phosphorous-nitrogen sugars, and ammonia/hydrogen or nitrogen dioxide/oxygen atmospheres... very interesting, but I'm trying to think of a boron-based life.
    Can anyone imagine a way in which a life form would use the oxidization of chemicals like methane, borane or silane for energy, without the intermediate states of complex sugars and ions as in glycolysis? Perhaps in heating raw input chemicals into unstable sugars, which can be stored or used themselves for generating or serving as the alien's "ATP"?

    Even though I admire your entrepid spirit in trying to find the physiology of aliens, I think it's guessing work.

    Life as we know it has DNA, RNA, proteins, is water and carbon based and whatnot.
    Who says these same laws apply to aliens.

    Perhaps they've got a biochemistry so different from ours, the very concept of something resembling DNA is missing in them.
    maybe their cell communication is based on radioactive isotopes? Is based on gasses and pressure between cells?
    Who says they even have cells? Maybe they are some sort of macro-cell the size of several cells we know currently.

    or perhaps they look just like us but are green...
    My point is, we just don't know. We are rediscovering our galaxy on a nearly daily basis so to speak. The universe, and even the closeby space around us, is still filled with mysteries. Trying to logically deduce any aliens that might inhabit it is impossible I think.

    On the bright side: Even though I'm not a believer in the whole: They kidnapped me and shoved a buttplug up my *ss, I do believe there is bound to be life ( by a broad definition) somewhere else in this vast universe.

    Well, could they use a borane/silane/methane reaction to sustain pyrolysis of their food, whatever it is, if it is raw materials or plant matter. It could pyrolize into usable chemicals, like coal pyrolizes with steam to form CO and H. They could use the pyrolized materials for their biological functions, since they might react with each other. Just thinking out loud.
    Silicon life might have solar panels, which it uses to electrolyze steam into hydrogen and oxygen... it uses oxygen to build its shell and cell walls with glass, and the hydrogen to generate chains of silane, which could be its DNA. It dissolves SiO2 with potassium hydroxide, and uses water to catalyze silane into SiO2 for removal. Its blood, and the atmosphere, has a lot of sulfuric acid, preventing carbon life from fluorishing...
    Creative things like that. Come on, guys!
    This is for sci-fi.
