<font size="2" face="sans-serif, arial, verdana">I thinkw e closed that one ages ago with the conclusions that
A) "Life" doesn't equal little greeen men but can be a 1 micro meter blob of green goo.
B) Life will be very common in the universe
C) How common intelligent life is is anybodys guess
D) How common humanoid type life is is anybodys guess

We just don't know how much advantage humanoid type life gives to a species... and we really need to if we are to make any resonable assumptions on its rarity/commonness

<font size="2" face="sans-serif, arial, verdana">Well this isn't really true. From a pure physical point of view and if we don't iclude some of the weird new age quantum physics that allows from WEIRD STUFF TO HAPPEN for no apparent reason... the universe has a maximum level of entrophy.

It is when everywhere in the universe the temperature will be the same and when all mass will be equally distributed everywhere in the universe. That is when Entropy will be maximal.

But since the universe is expanding... who knows... the classical entropy definitions don't allow for an "inclosed system" to increae in volume as that would mean that some "External" force would have to act upon it...

Re: OT: Earth\'s orbit changing?
 

The very fact that the universe is expanding makes it true... if the universe expands, the particles keep moving outwards, thus increasing entropy.

Re: OT: Earth\'s orbit changing?
 

If I remember right, the theory in question says that the sun's electromagnetic field initiated Earth's magnetic field. Once the dynamo effect kicked in, the Earth's field became self-sustaining. Eddies in the flow of magma are what cause the local maxima and minima, similar to the way weather is created in the atmosphere.

<font size="2" face="sans-serif, arial, verdana">Yes but you're forgetting the fact that the universe won't be expanding forever... it will prolly collapse back in again or slow expaing when the distances between particles become so great that the forces of gravity and whatever this force is that is pushing galaxies apart become equal.

Re: OT: Earth\'s orbit changing?
 

well, i bugged my physics teacher today, and the response i got was that: poles are always moving around, slowly, there is no such thing as a sudden move and they wont flip any soon.

anyone? http://forum.shrapnelgames.com/image...s/confused.gif
