Not much, what are they silicate chains?
I can't remember the exact reason why Carbon is the only atom that forms stable chains like it does but we went over this in a couple of the biochem and organic chem classes I took WAY back in college.
Silicon is a popular alternative for Macroevolutionists contemplating extraterrestrial life. It is in the crust of rocky planets (at least in the Solar System) in quantities rivaling that of carbon. Furthermore (again, from the Macroevolutionary viewpoint), life simply has to have a way to encode information. On Earth, carbon-based amino acids do this, but in theory silicon could about just as easily be used (as in computers and stuff). Macroevolutionary models of extraterrestrial life don't need DNA either (just a way to encode information), and now even water (hydrogen peroxide, H2O2, could be used, for one).
And, I thought one of Saturn's rings was, and is still being created from water vapor spewed forth from Enceladus? (Or is Enceladus spewing something else?)
And Triton needs a closer look. Io, too, maybe.
If this nonsensical Impact-Splash scenario had happened 4.4B years ago, a mars directly impacts the earth and slashes out the lunar mass into stable orbit beyond the roche lobe, we as water-rich critters wouldn't even BE here. That event would instantly release 10^31 J of KE, a gamma ray burser like the Shoemaker-Levy comet fragments impacting Jupiter in 1994, only of VASTLY greater magnitude.
What settles out AIN'T delicate molecules like H2O, NH3, etc; more like pyroxenes...this planet would be just as sterile as venus. So astronomy geniuses, how did earth's OCEANS get here as early as 3.9B years ago?
Guessing that Io's too hot to have water on it.
everything in that group can form chains but I thought only Carbon could form the necessary rings and other structures necessary. Maybe research has been done since that clarifies this? No I'm not a chemist, I just play one online
There is water vapor in Mars' atmosphere, and it's 99% evident comets have water in them.
That's why I said "maybe".
Don't be confusing the poor man with science.
Life, as we know it.
I don't pretend to be God and know that there are no other forms of life out there.
Polysilanes are Si-H chains and chemically similar to C-H chains but not as robust, they quickly photovolatize in our sunlight. Thus polysilane organisms can only develop on planets with huge cloud covers. This is why the little gray aliens visit earth at NIGHT. Also, living with very low light levels, they depend on polarization to see/discriminate objects, that's why their eyes are long ovals set at 90 degrees or so to each other.
No insult was intended.
"Water is only on this created earth."
That is certainly not true.
There are small iceballs that are frozen water that come from space and pellet the atmosphere of Earth, adding water that was previously not here.
There is so much 'rain' that it had scientists puzzled because it gave off a 'background' noise easy enough to be detected but very, very had to see. Like looking for a needle in a haystack. Eventually,
Satellites and the scanning equipment on them identified this 'noise'.
Many comets also have large amounts of water on them.
Snowballs on Fire. Isn't God Amazing???
Don't ping people behind their figurative back.
Wasn't trying to - I had already pinged him the post prior. Sorry, UG.
If you read the other comments, you would see that several freepers have pointed out that there is extraterrestrial water--most typing (telling) him that in a rather rude manner.
Then sorry, in turn, for comments 36 and 38.
Appreciate the info on polysilanes.
