Do you think silicon life is plausible? (Not possible, plausible.)

Silicon-based life would be no less likely than carbon-based.
Silicon-based life is highly unlikely.
What? LOL! Breast implants are made of silicon.
What about nitrogen and phosphorous-based life? or the many other hypothesized bases?

This question may be carbon chauvinism, but I can't see silicon life being as competitive as carbon life.

Hypothetically, planet X has trace amounts (less than 1% or so) of carbon, while it swims in Silicon. Would a silicon-life or a carbon life be more likely to form? would both form? Would both coexist or compete? Could they be both carbon and silicon based?

Silicon doesn't seem to bode well for evolution, as it can't form with as many other things as carbon. It also doesn't transfer heat well. The logistics of silicon life are quite perplexing. It's chemistry is somewhat restrictive. In fact, that is a theory as to how Earth, A silicon rich planet formed carbon-based life. Another theory is that carbon-silicons cosmic abundance abundance is 10-1.

I personally think, Silicon life would form and die quickly. I don't know what silicon could do about energy. It is less electronegative than carbon, which could end up being good. Amino's would be so problematic, though. It would use a lot of energy to do simple tasks, too. It doesn't look like it could survive long even with the odds in it's favor.

    I think it would simply be a matter of abundance. We are on a carbon and silicon rich planet, so there was lots of both to form life. The atmospheric pressure and make-up would likely be wrong for silicon life forms- there's no point if they'd just turn into sand because of all the oxygen, so carbon won out. On a silicon rich planet with the right conditions for silicon-based life, I see no reason why it shouldn't be as likely as carbon-life forms.

    Although Silicon-based life may be more unlikely than carbon-based life, it is plausible. You'd need to know a little about Chemistry to understand why life could not be based on Nitrogen (usually a gaseous state except at extremely cold temperatures) and Phosporous (a fairly reactive and volatile element that is simply not suitable for long-chain molecules such as those found in living organisms).

    Silicon can form covalent chains like carbon, but the bonds are weaker.
