extremely high CO2 content doesn't necessarily retain heat very well. The atmosphere of Mars is 95% CO2, and its average temperature is an unpleasant 27 degrees celcius, its considerably less dense than earth's atmosphere, but you get the idea. Venus also has a CO2 atmosphere with a little sulphuric acid mixed in, and has a so-called Runnaway Greenhouse effect, giving it a surface temperature near the melting point of lead. But unlike mars its almost 100,000 times denser than earth's atmosphere.
so the distance to its local star aswell as density make a massive difference to the temperatures a planet will have.
Oh for sure. If the atmosphere only consisted of one molecule and that molecule was CO2 then it would have 100% concentration but naff-all effect on temperature 
But if the discussion is still bandying around the phrase 'Earth-like' then we can't let the atmosphere go too far adrift. Reducing atmospheric pressure to compensate for 80% CO2 would probably result in the oceans boiling away if they consist of water.
Of course if you're going to define 'Earth-like' as 'Lots of white, blue and brown with a bit of green' then you quite a lot of lee-way to monkey around with things. Personally I'd define 'Earth-like' as being somewhere I could live without having to do anything worse than put on some clothes. If a spacesuit is a requirement then it ain't Earth-like.
Temperature isn't everything. For a planet to support life (ours, as in earth-like, no spacesuits) energy is needed as well. With an atmosphere capable of efficiently holding down heat generated by very limited radiation input you'd still fall short on any biochemistry.

I would love to see the curent eve universe much larger than it is now. Perhaps even 10 times the size. Still a small portion but many more systems to explore. I like the idea that if you wanted to you could head out for some time and eventually travel to ares where you could go for days and not find anyone. I cant see this happening to our eve in a hurry but it would be good.

I think it would get awefully lonely out there. The population (ie number of players) is not big enough to fill up a universe larger then the one we have now. Actually, 0.0 has so few people in it (relativly speaking) that the population can increase a great deal more before we actually 'run out of space'.
What will happen I think is that the more players we have, the more intense fights we will see for control of smaller areas of space.
But I'm wandering off here. It's interesting to see where a simple question regarding lightyears can lead to. And I'm glad that the Jumpplanner is appriciated

I have a feeling that with the impending carrier changes, we'll start to see a lot of alliances contract, because of the increased difficulty in maintaining starbases. Now, what would be the implications of that?

Btw, I always find it funny that 100 AU from Sun and we see habitable planets in EVE 
Not strictly impossible. In fact, a star several times larger and hotter than Sol would definitely have a habitable zone that much further out.
Our own sun is tiny and feeble next to some of the behemoths that are out there... There are starts in this galaxy alone that are the same size relative to OUR ENTIRE SOLAR SYSTEM as Sol is relative to Earth.
Yep, a small yellow dwarf :)
Another question, why are there no multi-star systems in eve? In real life it appears that more than half of the stars in our galaxy are twin-stars or even 3 or 4 or 5 circling around eachother.
There must be ONE system in the universe that has 2 stars, one relatively in the center of the solarsystem, and another one of such a perfect relative size/heat level, at such a perfect distance outside all the planetary orbits that it effectively doubles the "hospitable zone".
Like a 10th "planet" far far away sun orbiting the bigger central sun :D
Basically as if we somehow ignited Jupiter, mars might heat up just enough then :D

According to one of the backstories there are. In fact that story apparently (I've not read it) claims that you can only build jumpgates at binary systems. Having said that the stellar map only ever shows one star..
..but perhaps the navigation computers choose to ignore the other one. The other star is likely to be far enough away from the one the map shows to be indistinguishable to the naked eye and probably won't fit on the map unless you zoom it out a long, long way.

The Eve map isn't showing an entire galaxy, let alone an entire universe. The Eve map is showing a group of stars linked by jumpgates. I think I've heard that there's a backstory that actually says it's just another area in our galaxy.
Galaxies are big enough that each one could contain thousands of stellar empires without any of them knowing about the others.

That won't work. Planets move in their orbits and sometimes they end up 'right next to each other' other times they end up on opposites sides of the sun. The variation in radiation received in such a situation would be too much to sustain life I think. Either that or it would develop a really weird and impractical live/hybernate cycle.
