"Star to Life" ?

[sanjuro]

Is there a basic for life for all the universe or it had its own rules for each system?
----------------------------------------------
because (i read an article about that) in our solar system , jupiter act like a shield protecting earth (in a sens) and so earth peacefully make his life.
----------------------------------------------
(A theory in the article)

so we call them "Giant" (i think) (in another system)

and its start when gaz and dust compact together bla bla making big blocs that gravity make them suck gaz and become gaz-planet and take some "times" to make a real planet...

But then in the article says that most of "giants" seem to migrate
in direction of their star and make them very close to them...

----------------------------------------------
So about the life on our earth there is a basic about O O2 CO2 makes that life and the evolutionnary progress it is very slow .

But will they be some sort other "rules"

like you change the "O O2 CO2" for other name( you know what i mean)
and their are not on photosythesis bu on ????thesis.

and they don't need as much thing tha our base can handle...

So is there an possiblity that their the evolutionnary time is more faster or more slow than ours . and that they don't have the same basic...

----------------------------------------------
confusing? : it is normal

So the question is What are the ingredient for life ?

The classical approach:

?€? Right type of star. It shouldn't burn up too fast (so not too heavy) and probably shouldn't be a close binary.
?€? Stable orbit inside habitable zone (high enough temperature for chemical interaction but not too much hazardous radiation). An orbit is more stable if the planet has a considerable satelite (e.g. moon) and other planet's orbit's are not too close.
?€? Planet needs too have the right mass so it can maintain an atmosphere or at least liquid solvents (e.g. water)
?€? Probably: magnetic field to protect the surface from highly energetic particles
?€? Probably: Jupiter-type planet to keep us safe from comets and stray asteroids.

so i guess we are the one who had win the lottery first prize (lucky).
1chance/10 x no limit
hum we got our chance and now we made our earth ill...

nevermind , thanks for anwser me my question...




------------------------
I'm just newbie asking lots of question with a bad english...
always "why? and how?" ...
-don't search the leaves or the bottom , you'll find the anwser at the roots

It's a shame indeed. Life (on our planet) in general though, will most probably survive wat we are doing to the world in a great many ways or another. However, humanity itsself runs a considerable risk of extinction.
