Silicon based life forms
Silicon-based bio- dependent environments go in two directions: extremely hot, and extremely cold. The rest of the conditions are nothing special: organisms can withstand a substantially cataclysmic, noxious environment, as long as there is an energy gradient rather than a mere high energy. High temperature based silicon-based bio In 1891, German chemist Julius Scheiner described the possibility of silicon-based life. In 1893, British chemist James Emerson Reynolds mentioned in his opening speech to the British Association for the Advancement of...

But not all is lost for the possibility of silicon-based life. On an extreme world like Titan, there is no oxygen in the atmosphere and all water is frozen solid, so silicon is not oxidized right ...

Comparison of four (sulfur, boron, silicon and carbon) scaffolding elements and their pros and cons as main building blocks of biochemistry. Sulfur (e.g., amphiphilic polythionates []) forms chains with itself, and in an alternation with carbon,...

Silicon-based life is perhaps the most common form of alternate biochemistry explored in popular science fiction, most notably in the case of the Horta from Star Trek.The concept is an old one, dating back to speculations by H.G. Wells in 1894:...

For life on Earth, carbon is king. All organisms build their cells from carbon-based molecules. Scientists and science fiction authors have long speculated that because silicon atoms bond to other atoms in a manner similar to carbon, silicon could form...
