Silicon-based life Like carbon, silicon can create molecules that are sufficiently large to carry biological information; however, the scope of possible silicon chemistry is far more limited than that of carbon.

Silicon in a diamond cubic crystal structure. Like carbon, silicon can form four stable bonds with itself and other elements, and long chemical chains known as silane polymers, which are very similar to the hydrocarbons essential to life on Earth. Silicon is more reactive than carbon, which could make it optimal for extremely cold environments. [6]
They suggest that Earth-like planets may be very rare, but non-carbon-based complex life could possibly emerge in other environments. The most frequently mentioned alternative to carbon is silicon-based life, while ammonia and hydrocarbons are sometimes suggested as alternative solvents to water.
Carbon's importance to life is primarily due to its ability to form numerous bonds with other elements. [17] There are 16 kilograms of carbon in a typical 70-kilogram human. [18] Silicon-based life's feasibility is commonly discussed. However, it is less able than carbon to form elaborate rings and chains. [6]

Here's how we compiled the list: We pored through 30-year average snowfall statistics of hundreds of locations in the U.S. from 1991 through 2020. We considered only those towns and cities with a ...
He deduces that it burrows through solid rock by secreting the same corrosive substance that has killed the miners. Spock adjusts his tricorder to scan for silicon-based life, and confirms that the creature is the only such lifeform for miles. Kirk and Spock happen upon a chamber containing thousands of the silicon nodules.
