The size of intelligent aliens

Nope, never.

what is the source of this image?

intelligence isn't even a well-defined thing in humans
it would be hard to tell
also consider that aliens can be far different to us

>>8941374
With the brain size of a housecat? Doubtful

>>8941374
Actually our definition of "human" and "intelligence" is based purely in our living since we exist. Intelligence is not well-defined, and it needs a reference to something. You can say that a living being is "intelligent" seeing it behavior and what does it does to it's environment. We humans dominate our planet just because of this, we fucked around everything and transformed a green and blue ball of tird in a giant ball of concrete and human made energy.

You should research how we actually became smart and what drove us to it.

how's this for an answer?
we don't fucking know

>we can't find a 100% conclusive answer so let's not bother exploring this line of thought at all

>>8941422
well we could look into what kinds of alien life are most likely to exist for starters
astrobiology

Depends on the gravity and amount of whatever gas they have to breathe to stay alive.

>>8941374
There is probably a limit about how small an intelligent brain can be, but we don't know for certain.
Probably small as a cat is still possible.
Consider that brain dimension isn't everything, even in humans it varies considerably, and some animals even have a bigger one than ours.

idk if this is really a thing when we are heading to things that we don't know, our position on space and our gravity woudn't be unstable to other environment "living beings"?

>>8941374
Yes. As long as the mass of there "brain" organ is roughly equivalent to the ratio of brain to body size as it is in humans. Also, On higher gravity worlds it is almost guaranteed that human-level-intelligence equipped creatures would be smaller (albiet more densely muscled). On lower grav worlds they could be larger than humans as well.
