How would alien cells work? Let's say alien life exists almost everywhere, how would cells be similar to ours? or would they work absolutely different from each other? Would they share something in common like the transmission of information from cell to cell?

I want to make some alien designs that stay as far away from fiction as possible but cells are a big problem.

Does not necessarily need to be in a planet similar to ours.

there are no aliens.
grow up.
we are all there is out there

next you'll be telling me how are the cells structured in the tooth fairy
stop fantasising about nonexistent 'aliens'
>>
>>10194642

Well, for example, all life on Earth is based on carbon, so we just ASSUME that life on other planets must also be. But there's no real reason or proof to indicate that would necessarily be true.

I've been to space. there are no aliens
I checked fucking everywhere

what could be some alternatives?

>>10194687

Silicon is directly below carbon on the periodic table, so that seems like a logical choice, as elements in the same column typically exhibit similar properties. (see also the movie "Evolution" starring David Duchovny.)

>>10194642
no cells
>>
>>10194719
ohh, how would that work?
>>
>>10194726
the same way cum is a sludge that oozes, but it gives live to everything. think of an alien that oozes and slimes but has no cells
then you have your answer
>>
>>10194715
Carbon is also 10x more prevelant in the Galaxy than Silicon, however what really smashes Silicon-based life theories to pieces is that despite Silicon being a lot less common in the universe than Carbon, it is nearly 1000x MORE prevelant than Carbon in Earth’s crust, yet life here still became Carbon-based.

Silicon is crap.

Why do they have to be cell based.

What if exotic conditions in the layer of metallic crystalline hydrogen of a gas giant led to the formation of some kind of lattice. One which can self replicate and which evolved over time. Eventually forming co-operative communities and then larger entities capable of conscious thought.

The conditions at the core of a gas giant or black hole are probable much more stable than on earth over very long time periods.

Only these aliens have problems which would prevent them from ever becoming spacefaring.

They are trapped in a gravity well too large to escape and are dependent upon exotic conditions much more difficult to carry with them out of their habitat.

Open your minds seriously. Why does alien life have to resemble what we are on any level...
>>
>>10194642
You're asking a question that is outside the scope of our current understanding. To answer it you'll have to discover alien life forms and study their biology.
>>
>>10194644
Why would you think that?
Do you even have an inkling of the scale of the known universe?
>>
>>10195006
my balls are bigger than the universe
and there are no aliens there

but to be serious for a moment where are all the von neumann probes up in our assholes. even one civilization out of the trillions supposed to exist would have to make 1 von neumann probe and we would all be fucked by now already

>>10195022
The universe is fucking big and intelligence is probably rare but it's there.
It happened here so it happens else where.
There will be lots of planets out there very similar to ours

Carbon is a pretty versatile when it comes to chemistry.
If you're going to be a life form based on chemistry then being carbon based is pretty optimal.
>>
Since a large number of exoplanets discovered tend to fall outside the habitable zone of their respective stars it doesn't seem unreasonable to assume that life could evolve from colder compounds, such as ammonia or methane based organisms rather than water or carbon based.
These cooler forms of life would likely never get beyond the simpler stages, or at most would take a far longer time to evolve due to a slower metabolic process. Thoughts?

What would be the powerhouse of the cell?

It's an interesting thing to think about, but we can't really get far.
As we currently know it, all life exists here exclusively on Earth, and all life is DNA-based. That being said, DNA and life itself only arose because of the specific conditions present during the early stages of Earth's life.
Cells only exist as the building block of lifeforms because early simple forms of life evolved under the pressures and conditions present at the time. It could be possible that similar life forms exist elsewhere in the universe, but it's hard to imagine any kind of life being able to thrive without some kind of mechanism for evolution, being able to adapt and survive in a changing environment over time. As far as we have seen, evolution is only an inherent property of DNA-based allowed by the occasional, necessary, accidental errors of its specific molecular machinery that has been fine-tuned for billions of years over specific conditions.
Anyways, what I'm trying to say is that aliens having cells would be extremely unlikely unless similar conditions were met during their evolution, and the existence of their evolution implies that they would've needed fine-tuned cellular machinery programmed by DNA or something similar that made occasional errors just like ours does. Basically, alien life would probably have to be very, very, very similar to our own basics and that means their planets would also have to have very, very, very similar conditions.

>>10194642
just look at some different cell types of multicellular organisms and single-celled ones, and then just invent something fancy

but a cell-like structure is essential, because it lets you control your internal microenvironment so your chemistry can be remotely functional. Something like DNA that can be inherited is also really important.

Semen is comprised of cells.

The function would depend on the environment the "cell" lives in.

Viruses do just find without cells.

name one virus that has a life cycle independent of cells

I want you to think about what you just said.

They'd probably look like a bunch of wacky silly putty like how ours do.
>>
>>10195022
Jesus fuck this better be bait from a 20 something year old essentialist. It's like you're stating taking a scoop of water from the ocean and saying it's absolute proof there's no fish, turtles or any life in the water. Clearly you have read nothing about the speculative topics so as far as your own bias. Shame on you.
>>
>>10194642
I'd imagine something similar to archaebacteria.

How about an amorphous alien made of pure energy?

They would most likely look similar, evolution has shown that this is the most effective form.

Only on Earth.

I've seen some speculation that boron would be capable of forming the kinds of complex polymers necessary for life
>>
>>10194726
there's several kinds of macroscopic multinucleate organisms with no internal cellular divisions like the plasmodium stage of slime molds, some fungi, Gromia Sphaerica, and Valonia ventricosa
