Silicon is not a good base for life, it is interatomic bonds are too stable, although silicone (compounds of silicon and carbon) might do. Other elements that have been suggested include: sulfur, boron and nitrogen compounds, and maybe germanium. For carbon-based life, almost certainly the most common type, there are several possible solvents. We use water, at lower tempeatures one can use water-ammonia mixtures(liquid down to -176 C) or methane or more complex hydrocarbons; at even lower ones (or higher pressures, hydrogen). At higher temperatures liquid sulfur could be used. ______________________________________________________ Get Your Private, Free Email at
