yupp. silicon life is theoretically possible. but not practically. the complexity required to obtain "life" in any meaning way is by carbon only.
if the circumstances required for development of life are present. carbon molecules will take up the opportunity mich quicker tham silicon
Is Silicon-Based Life Possible?
//
Why do people hypothesise that silicon-based life may be possible? The reason is simple. Silicon is below carbon on the periodic table and silicon can also make four bonds. So, it stands to reason, you could just as easily make complicated molecules with silicon. That makes perfect sense, except it’s not true. Why is that?
So, let’s contrast silicon and carbon. They can both form four bonds. On Earth, silicon is far, far, far more prevalent than carbon. Basically, silicon is found in sand and rock. In the Earth’s crust, silicon makes up 28%. Carbon, in contrast, is about 1,000 times less common. Yet carbon makes up life, while silicon doesn’t. If silicon were a contender, the fact that it is so common would give it a huge advantage.
So why does silicon fall short? Well, to begin with, when carbon makes four atomic bonds with all of its neighbors, the bonds tend to be of the same strength. In silicon, the first bond is much stronger than the others, which means the first bond is far more stable than the others.
It’s because the first bond is formed when the electrons from each atom reach directly to the other atom in a metaphorical handshake. The other bonds are formed from electrons that are further away and they effectively don’t get as good a grip. It is like when you have to stretch yourself too much and you just are able to give your friend a high five in the distance through all other people.
Another thing is that when carbon connects with other chemicals common in organic molecules, the bonds are of similar strength. Carbon–carbon, carbon–oxygen, carbon–hydrogen, and carbon–nitrogen are all pretty similar. That means that, from an energy point of view, it is pretty easy to swap out atoms, which is the physicist’s way of saying that chemical reactions are way more feasible.
However, the silicon–oxygen bond is much stronger than silicon–hydrogen, silicon–carbon, or even silicon–silicon. That means that it’s tough to break them apart once silicon interacts with oxygen. This makes the ease and versatility of silicon chemical interactions far lower than the ones involving carbon.
And, about that silicon–oxygen bond compared to the carbon–oxygen one. When you breathe, you take in oxygen and breathe out carbon dioxide, which is given by the chemical formula CO2. The corresponding silicon molecule is SiO2 or silicon dioxide. The more common word for that chemical compound is ‘rock’.
Thus, a silicon-based creature using oxygen as part of its energy cycle would be breathing out sand. that'd be quite a sight, eh?? I think there is one such piece of sci-fi where the author has done this to one of the characters- (if you find out, lmk!)
So, while a simple understanding of the chemistry of carbon and silicon suggests that silicon-based life while "technically" possible if you dig a bit deeper, it seems that silicon-based life isn’t really all that likely. Silicon here is at a huge probabilistic disadvantage in terms of energy stability, the temperature of Earth, the atmospheric pressure and other such variables.
Initially, the chemistry seems compelling, but I think that the most compelling argument for the advantages of carbon is simply the fact that life on Earth is made of carbon, in spite of there being far more silicon around. If silicon were competitive, a silicon-based lifeform here would have come into existence and outcompeted our ancestors. And we, my friends, would have been out-glassed!

pls let me know if i have made any errors. will rectify it. written in post haste, and not really proofread or anything. also if you want to add something, you are most welcome! i am here to learn too.

tag your fellow carbon-based life forms!!!
Carbon is in all living things as far as I'm aware. When you burn something organic its carbon gets released into the atmosphere. Gasoline is made up of dead dinosaurs. We burn it to fuel our motorized vehicles.
We're breathing in dead people.
Carbon hits different
Important question
How We Stand Up to Putin and Stop Climate Catastrophe
How do we stand up to Putin and avert a climate catastrophe at the same time?
Quitting our addiction to fossil fuels. Here’s how we get there.
In response to Russia’s invasion of Ukraine, the West has snapped a series of sanctions into place.
Russia is the world’s second largest crude oil exporter and the primary source of global natural gas. Regardless of the short-term effects on our pocketbooks, over the longer term we need to transition to renewable energies if we have any hope of keeping the earth habitable, and freeing our economy from the influence of geopolitical foes.
This is where carbon dividends come in.
It works like this. We put a hard cap on the amount of carbon we allow into the economy. Permits up to this cap would be issued, and energy companies could buy them in quarterly auctions. At every mine, refinery, and port of entry, these companies would have to use a permit for every ton of carbon dioxide that would be released into the atmosphere once that fuel is burned.
When they run out of permits, they cannot extract or import any more carbon-polluting fuel.
To keep the climate from rising 1.5 degrees celsius above pre-industrial levels – the goal of the Paris Climate Accord – we need to slash emissions by roughly 90%. Accomplishing this by 2050 would demand reductions of 7.5% per year. Currently we’re decreasing at a rate of 1.2% per year.
With a carbon cap, in order to ensure we meet our goals, we could simply decrease the amount of permits issued by 7.5% every year.
But how would we do that without Americans getting clobbered by higher prices at the gas pump? That’s where the carbon dividends come in. The revenue from selling the permits will be distributed back to the public as direct payments, no strings attached.
For the majority of middle class and poorer Americans, the dividend will more than cover any increase in fuel prices, and they’ll come out ahead. The people who produce the most carbon emissions are by and large wealthy, and can afford the hike in prices.
The earth’s capacity to absorb carbon is a natural resource, one we should share equally, instead of giving the wealthy and oil profiteers free reign. Plus, everyone benefits from a cleaner planet.
One study found that a quarter million premature deaths would be prevented over the next 20 years in the United States with a carbon fee and dividend program.
I know what you’re thinking right about now. Sounds nice, Bob. But it’ll never happen. Don’t be so sure! The idea is notably popular across the political spectrum.
Carbon dividends were first proposed in 2009 in a bipartisan bill, and subsequent plans have come from both Republicans and Democrats.
And there’s already precedent for parts of this program. Since 2009, the Regional Greenhouse Gas Initiative has capped and sold carbon permits to power companies in 11 Northeastern states. It is boosting their economies and has proven politically resilient.
And in Alaska, every resident receives between $1,000 and $2,000 annually from the Alaska Permanent Fund, which invests the state’s oil royalties. Over 80% of Alaskans say it improves their quality of life.
We treat gas prices as something out of our control, giving dangerous amounts of power to petro-states like Russia – with alarming consequences. By weaning ourselves from gas dependence, we’d gain relief from dirty air that kills millions globally; relief from the constant hemorrhage of government subsidies for fossil fuels and from wars for oil; and, above all, relief from the ongoing destruction of the earth’s climate.
None of this is impossible.
The best way to contain Russia, and build a sustainable future, is with a carbon dividend.
chemistry is cool go check it out
heres some designs for atoms I made! There are a lot more that I am willing to share, they're just badly drawn and made for my eyes only so I'll post more of them laterrr :)
more atoooooms
these designs are very random (not so much carbon) but parts of them do have explanations which i am too tired to say at the moment
sorry chemistry class got me like
Carbon in real!!!!!!
カーボンドアミラー
ルーテシアのカーボンドアミラー。
フランスのオレカストアで購入。
https://www.oreca-store.eu/
ミラーカバーの部分のみがウェットカーボン、ミラーベースはレジンの艶消し黒塗装。ミラーカバーのカット面処理がとても雑でミラーベースと合っていない。フェーズ1用だからなのか、ドアパネルとの合いも良くなく面差が目立つ。値段なりか値段以下。後で気づいたが、おそらく左ハンドル用なので、右は良いが左の鏡像が見たいところに合わない。取付用のM4のボルト (左右で6本) は付属していないので、自分で準備する必要がある。取付後に気づいたが、外気温センサがミラーに組み込まれているようで、外気温が表示されなくなった。
ミラーカバーの固定は下側のビス1か所と接着を併用。
取付自体は簡単。ドア内側の三角のコーナーカバーを引っ張り、パネルの穴をふさいでいる白い発泡素材をはがすと二つの止め点が見える。(現車の右側は取り外し履歴があったようで黒い発泡素材になっていた) もう一点の止め点はコーナーカバー前側のドアインナーパネルにある。
ドアパネルと面が合わない。ミラーカバーとベースの隙もガタガタ。左側は鏡面を目一杯内側にしても見当はずれな外側を向いていて役に立たない状態。
ドアパネルと面が合わない要因一つ目。ミラーベースが下側グラスランを避ける形状になっていないので乗り上げる。
ドアパネルと面が合わない要因二つ目。ミラーベースが前側グラスランに乗り上げる。ここも避ける形状になっていない。
純正ミラーの質量は1228g。カーボンミラーは図り損ねたがおそらく200gぐらい。片側で1kgぐらいの軽量化になる。
さすがに我慢ならない状態なので、後日ミラーベースを削って収まる様にしたり、ミラーを張りなおしたりで、ましな状態になりました。
