Methane based life forms
Web13 nov. 2024 · Scientists have suggested life elsewhere in the universe could be based on other elements, such as silicon, boron, sulfur, or maybe arsenic or other metals — possibly even methane-based life. Life forms of these natures would be rather exotic. However, these would be but carbon substitutes, of a sort, for similar self-replicating life. Web27 jul. 2015 · Actually, focusing on organic matter and liquid water is not nearly so parochial and chauvinistic as it might seem. No other chemical element comes close to carbon in the variety and intricacy of the compounds it can form; liquid water provides a superb, stable medium in which organic molecules can dissolve and interact.…For the moment, though, …
