Does non carbon based life exist somewhere in the universe?
Question asked by: mrquestion

No-one can say no in answer to this, because we don't know what else is out there.
However it seems likely that due to its chemical properties that life elsewhere would need to be based on carbon if it was of any size, although we can't say for sure.
There aren't that many elements that seem to have the flexibility that carbon does, the stability and abundance... however it is possible that something like silicon could perhaps be a candidate for life forms elsewhere; for very simple lifeforms there might be a larger range of candidate elements.
