"The Case for Non-Carbon Life": Maybe silicon works in very hot places



The Case for Non-Carbon Life”, from Unveiled (6 minutes).


The basic idea is that silicon might behave more like carbon at very high temperatures (on hotter planets, maybe on “hot Jupiters”, maybe on Venus now).  The video discusses extremophiles on Earth.

The video notes that arsenic can substitute for phosphorus in some life forms (like in Mono Lake in California).

Silicon’s 4  covalent-available electrons are in the third layer deep which makes their compounds less “hardy”.
  
The video speculates that even dark matter could be alive.
