What if life in the universe is actually incredibly common, but we were just looking in the wrong places (le mars)

This is what I've been thinking. it couldn't even be a planet, just a tightly packed nebula with enough oxygen, co2, water, right distance from a star, mostly stable temperature would be enough to support simple to complex life.

nebulae are incredibly sparse. The tight packing of planets is thanks to gravity. Unfortunately, space-based life is unlikely

Its for this very reason you're not going to get have liquid water for any life as we know it.
Not to mention that Oxygen is pretty reactive and won't hang around in its molecular form if it has other stuff to bind to.

And what would you know about 'energy'? What if there is a lifeform that doesn't run on energy, but the opposite?

Anon seems to understand everything about every possible lifeform in the universe, so he already decided that 'energy' is needed for life. He's also an expert on energy if you were wondering; he knows more about energy than the top physicists in the world.

Microbial life could easily be very common and that's generally accepted as a legitimate possibility

Many of these ice planets have subterranean oceans with alien octopus and squids living there. Cephalopod civilizations are likely everywhere.

Only in the case where there's sufficient heating
>Cephalopod civilizations are likely everywhere
Why? We don't see Cephalopods making civilizations in earth's oceans.

Earth has too many other competing lifeforms that keep the squid people down. On the ice moons the squids would have room to grow and become the dominant lifeforms. This is similar to how humans would never have gotten a chance if that asteroid didn't wipe out the dinosaurs.

Why wouldn't they be subject to competition from other lifeforms on a subsurface ocean?
If there is life on say, Europa, its going to be a whole ecosystem.

I've heard this argument before, from UFO lunatics mostly. "Well you don't know how life evolved there". bitch, always resource limited. you can't have it any other way. if it multiplies it does that until all resources are taken over. you can't have useful shit lying around for too much, in nature. something is getting that. we have no proof on Earth that life just stops spreading if it can spread, for reasons of "well you know man, like...we wanna chillout and shit, not be stressed, have everything any individual needs"

This is basically what the maximum power principle is.

No air-sea-land interface means much lesser diversity of life in the Europa seas. With the absence of their traditional predators, the invertebrates are much more likely to become the apex predators.

That's why there's such a fuss about finding an origin of life on earth. If life could start more than once here and there's several ancestors to life today, then it's much more likely that life popped up somewhere else too. Life is rare on earth = life is rare in the universe. If we prove life ISN'T rare here, we can hope there's life out there too.

Water is pretty common, but you're not going to get it as a liquid in a nebula of it because there's no pressure to keep it in its liquid state. Having a planet with sufficient gravity (in relation to the solar flux) to hold onto an atmosphere is a prerequisite to having liquid water

what is the optimal form for life? does it need hands and legs?

[Anonymous No.15563529]

>>15563490
Any successful species will probably have some sort of hands or tentacles that can grip and manipulate objects and use tools. Because they will need to be able to create spaceships. All species that do not make space ships will die when their sun eventually dies. Or any collision would wipe them all out. As far as I am aware, there are no natural objects in existence that any creature could just get in and travel space with, so they would have to be able to build ships out of different metal arrangements.

There is no optimal form of life, life is going to be adapted to whatever conditions it finds itself in even if its a species that's more of a generalist.

[Anonymous No.15564026]

There are two types of dominant lifeforms in the universe. On planets with land and water like Earth, bidpedal hominids or reptilians are the primary life. On purely ocean worlds like Europa and Enceladus, squid-based lifeforms dominate. There are no others.
