A question on alternate biochemistries

I know that scientists have doubts about alternate biochemistrys such as sillicone and sulfur due to chain complexity, reactivity, abundence, ect. But would it be physicly possible if specific compounds could have more more complex moleculer chains and less/more reactivity on a planet with different conditions from our planet such as a denser/thiner atmosphere, air pressure, extreames in tempeture, ect. that unobsevable in curent conditions?

my opinion is, that somewhere out there it probably does exist. who knows if we'll ever find it. heck we may even create it someday.

check this page out
en.wikipedia.org...

There would have to be a fundemental discovery in the way we believe bio-chemistry works. As of how we understand it now your answer would be a definite no.

To believe that we have a total understanding of everything in the universe at this point is ridiculous so who knows what remains to be discovered.

I have read that page from top to bottom often just for fun.
However that dosent answear my question i would know if what i stated in the OP is possible under our current knowledge of the universe.
Sorry for being so critical of your post, it is much appreciated.

Thank you for the post. I hope that we discover something like this soon and your right about how close minded it is to belive that we know everything.

what exactly is an alternative bio chemist

reply to post by connorromanow


An aleternative biochemistry is somthing that is not based on carbon like we are. For example sillicone based beings are speculated to look just like living moving crystals.

Edit: I would try looking at the wikipedia page such the one that is linked to in Optimus Primal's post.

Well last year NASA said they've found bacteria that uses Arsenic instead of Phosphorous. So yes, alternative biochemistries are very possible.

This is a bit of an oxy-moron because once we discover it than it fits into the human belief model no longer making it alternative. I believe the orginal post was thinking in more extreme terms.
