In response to "there is good reason for it chemically. -- nm" by loosilu

I'm sure. I nearly failed chemistry so you geeks get to tell me stuff.

but I always wondered. And another thing...why does life need oxygen. I'm not looking for an answer just askin'...

Life is adaptable. Maybe more than we think. I think in 500 years some of our assumptions are going to sound cute.

oh by the way, the sulfur based life does not use oxygen (which is unavailable in the deep ocean). - loosilu Dec 2, 07:15 1
- And just speculating, I am guessing that with this new bacteria, Arsenic takes the place of oxygen. -- nm - loosilu Dec 2, 07:16
I would rather let Reagen answer the chemistry, but it has to do with the number of available bonds. It has long been thought that Silicone could work - loosilu Dec 2, 07:14 5
- It's more to do with the size of the atom. - Reagen Dec 2, 07:19 2
  - ps. can arsenic form chains, like carbon? -- nm - loosilu Dec 2, 07:23
  - ah, thanks. -- nm - loosilu Dec 2, 07:20
- yeah, i always understood silicon as the most likely if this sort of thing was found....nm - x Dec 2, 07:17 1
  - right, but as previously stated I am thinking the arsenic replaces oxygen in this case. -- nm - loosilu Dec 2, 07:18
