Is any of that relevant to life being based on elements other than hydrogen, carbon, oxygen and nitrogen?You didn't even seem to know what a hybrid orbital was. How can you call someone a fool about C chemistry if you don't even know how C bonds?

"...These four elements, Hydrogen, carbon, oxygen and nitrogen, also provide an example of the astonishing togetherness of our universe. They make up the “organic” molecules that constitute living organisms on a planet, and the nuclei of these same elements interact to generate the light of its star. Then the organisms on the planet come to depend wholly on that starlight, as they must if life is to persist. So it is that all life on the Earth runs on sunlight. I do not need spiritual enlightenment to know that I am one with the universe -- that is just good physics..." George Wald
Is any of that relevant to life being based on elements other than hydrogen, carbon, oxygen and nitrogen?
uh huh.... cool story.What a load of pseudo-philosophical mumbo jumbo! Seriously. This isn't science, dude, this Wald dipping his toes into philosophy and coming across as a new age nutter.
So because H is fused in stars and it occurs in organic chemicals (NOT ALL OF WHICH ARE RELATED TO LIFE, I might add) then it must be that H and C are the ONLY things that could EVER be life???
Wow.
That's seriously woo-woo sh*t.
That would be showing it wasn't relevant, my dear, not showing it is relevant. So I'll ask it another way, how is that relevant?Apparently so. Wald talked about it. The fact that you didn't see the relation just shows this is yet another science you know nothing about but you THINK you do sufficient to call others "fools" when they fail to agree with your woo-woo bs.
uh huh.... cool story.

my dear, not showing it is relevant. So I'll ask it another way, how is that relevant?
More like pointing out to you who you were dismissing. And his observations were most certainly based upon science.Appeal to authority. I was talking about the post you attributed to him. That wasn't science. That was philosophy (new age sh*t)
As proof that all life in the universe is based upon hydrogen, carbon, oxygen and nitrogen as these are the lightest elements that achieve stable electronic configurations (i.e., those mimicking the inert gases) by gaining respectively one, two, three, and four electrons. Gaining electrons, in the sense of sharing them with other atoms, is the mechanism of forming chemical bonds, hence molecules. The lightest elements make not only the tightest bonds, hence the most stable molecules, but introduce a unique property crucial for life: of all the natural elements, only oxygen, nitrogen and carbon regularly form double and triple bonds with one another, so saturating all their tendencies to combine further. Sounds like science to me.The fact that YOU POSTED WALD'S DISCUSSION WHICH TALKED ABOUT IT means it wasn't relevant? WHy did you post it?

So you are saying I can't say...If you don't understand Carbon Chemistry you can't say anything meaningful on it.
Again... pointing out that you - an anonymous internet poster - are dismissing the scientific beliefs of a distinguished Nobel Laureate.LOL.
You love you some appeal to authority. Doesn't have to make any sense, you just have their bona fides. LOL.
You know next to nothing about how science operates. Go home, poser.
I'm more than happy to let others decide which one of us understands how science works.You know next to nothing about how science operates. Go home, poser.

Again... how do carbon bonds have anything to do with life being based upon something other than carbon?If you don't understand Carbon Chemistry you can't say anything meaningful on it.

So what other elements besides hydrogen, carbon, oxygen and nitrogen do you suppose life could be based upon?Honestly I wish that made any sense. Because every element below C can form a completed outer shell octet.
That's what BONDING is about. Sheesh! Even Na creates a stable octet when it snags an e- from Cl.
What does that even MEAN???
What??? This treats all bonds as the same! They are nothing of the sort! What about IONIC BONDS? LOL.
You are talking here about COVALENT BONDS in carbon-based compounds but that isn't all bonding. What about Boron? It forms nice covalent bonds with O (you ever make slime with PVA glue and boric acid?). Boron is lighter than C.
That isn't even close to right. The bond enthalpy for C-C is 347 kJ/mol while the bond enthalpy for H-F is 565kJ/mol.
What do you mean "most stable"????
There's that orbital hybridization I was talking about. You know...the stuff you said is "irrelevant"? LOL. Here you are talking about it again.
Yes, double bonds are usually stronger. But that's not the only metric for life.
Funny thing is that all this talk about organic chemistry (and it IS very interesting chemistry) is that organic chemistry is NOT always and exclusively related to life. There is literally nothing special about organic chemistry in life vs non-life.
It occurs in both settings.
Says the anonymous poster who dismissed a Nobel Laureate without ever stating which other elements besides hydrogen, carbon, oxygen and nitrogen that life could be based upon.And again, pointing out that you, an anonymous internet poster, don't really know what he's talking about from a technical point of view. Just because HE got a Nobel doesn't mean that every word out of his mouth is ipso facto gospel truth. And it CERTAINLY doesn't mean YOU know anything about it.
So what other elements besides hydrogen, carbon, oxygen and nitrogen do you suppose life could be based upon?
Look... you are arguing that life isn't necessarily limited to being based upon hydrogen, carbon, oxygen and nitrogen without having anything to back it up. I at least provided expert testimony on why all life in the universe must be based upon hydrogen, carbon, oxygen and nitrogen.I love how you dodged every point I made. Hilarious!
You are worse than a Creationist with their Gish Gallops.
Sheesh.
