No other rocky planets have been found. Most planets found are large gas giants orbiting very close to their stars.

No mention of observational bias. What's easier to detect from twenty thousand light years distance? The gravitational wobble induced by a Jupiter or the gravitational wobble induced by an Earth?

We've seen what we can see. I hate it when I catch you guys just saying what helps you.

Vade, when it comes to paleontology, I must defer to your superior knowledge. On astronomy I think I know a few things.

Deem could have phrased this better, but the gist of what he is saying still holds. It is true we cannot detect Earth sized planets yet, but the giant planets we do find tend to be very close to the star. Almost every astrophysicst beleives they formed further out and drifted in. This would have disrupted the orbit of any earth-like planet.

In other words, what we are finding discounts the idea that earth-like planets are common. The 'norm' for a solar system, is for a big boy to spiral in and wreck havoc.

When you add up all of the odds, as big as the universe is, the odds are GREATLY against even ONE earth existing. I will post a link on that later.
