Thread: Do you believe in aliens(extra terrestrials)?

What if these aliens need none of those things o.O
Maybe their bodies produce it all, or don't need any of it :O

> - there are a lot of preconditions for a planet to be able to develop life:
> * needs proper distance from its star

Either that or it has to have a lot of geothermal energy like the moon IO does.

> * needs rotation (not too fast (life needs recovery or lots of energy), not too slow (weather...))

Unless it's far enough from the sun that the temperature on the sunny side doesn't get too hot (or has geothermal energy).

> * needs to be far away from areas with lots of mass (supernovae...)

Please explain a bit more. I think I know what you mean, but it's not totally clear.

> * needs a moon to stabilize its axis

I doubt that's a requirement. If it is, it's definitely news to me.

> * needs a magnetic field to keep away bad things of all sorts

or the aliens live underground or have evolved to be immune to radiation.

> * needs to have an atmosphere

Unless it's a civilization of androids that killed off all their makers.

> * which is not toxic

toxic is a relative thing. Just because it's toxic to us, doesn't mean it's toxic to a silicon based organism.

> * but the planet may not entirely consist out of gas

Like Jupiter? Probably true. It would need too much mass to stay together if it's all gas.

> * needs to feature many different elements (and not too much of the heavier ones)

Debatable. Obviously it can't be make entirely of just a few elements.

> * its star may not be too large (burns too fast) or too small (doesn't emit enough energy)

Unless it has a lot of geothermal energy.

> * must feature water (or some substitute) and carbon (or some substitute)

That could mean just about anything, so sure...

> * and must feature temperatures which keeps these things fluid and solid respectively
> * all of the time

Our planet doesn't -- water is solid in the winter and liquid in the summer.

> - for aliens to be able to communicate with us, they need a brain (remember things), common sense (remember useful things), hands (make use of the stuff remembered), and the ability to move (tell someone else)

Brain - yes.
Hands - Well it would make things much easier, but as long as they have something (hooves, tentacles...) that they can build things with, they should be fine.

I am just happy I finally got my surface normals to work in openGL-- you know, for the lighting.

On another tangent regarding the Great Magnetic Field: the polarity of the earth is due to reverse soon, so don't go spending too much on a compass or you will find yourself in the exact opposite place of where you meant to be.

I think Snafuist has been suckered, which is a shame because the program itself needs more better programmers

or just change which side is painted red
