Another Earth is Out There!

yes, but there is more to earth than appears. while a similar size planet might be relatively common in the universe it doesn't mean that an Earth like planet is common. Earth may be just the perfect coincidence of events to allow us to exist. The perfect size planet at the perfect distance from a perfect size and type of sun...not too warm, not too hot. Water. Atmosphere. These two may be products of the first set of perfect coincidences. Then we have a single moon, large relative to the planet it orbits and close. It keeps our axis straight, allows for weather and season cycles that are predictable and long enough for growing. Another moon, a smaller moon, or a moon farther away would not necessarily allow these things. Now, the universe may well be near infinite so that allows for quite a lot but my guess is that the numbers of "earth-like" planets that are "just right" may be quite small.
i dont understand why they always assume that these other earthlike planets would have to be similar to earth 3 billion years ago.
why couldnt it be like us or even far advanced? especially if the universe was all created at the same time, to me it would make sense to have planets that are just as advanced as us.....

Great post. This is because of the inherent arrogance that we as a human race have. This is why it is man made global warming and absolutely nothing to do with the sun. (not to drag this to the cave)
I also agree some of this 'research' is an incredible waste of money. Luckily there are hundreds of millions from the 'stimulus' package that will help determine if there are other moons like ours that exist.
If we find intelligent life on another planet the way we think of ourselves and our enemies our government will totally change
It's amusing how hot and bothered the idea of other planets with intelligent life gets some people.
This is about like saying that Ames is twenty miles away from Des Moines, so therefore, every city exactly like Des Moines will have a city exactly like Ames twenty miles away from it. You would think real scientists would laugh this guy out of the room.
not really like saying EVERY capital city the size of des moines will have an ames.
More like saying that a good place to look for a state university is to look at it as a "satalite" of a state capitol/or major population center. Since we don't have unlimited resources to scan the entire universe, and for lack of a better strategy lets start by looking where we think the PROBABILITIES of another earth are slightly higher then any other "guesses."
No one is even coming close to saying that "every des moines has an ames". Or that every set of dupicate circumstances produce the same results. Just saying Capitols/population centers MAY increase the likelyhood of a State university being within 50 miles. So lets start there. See Ann Arbor/Detroit. Not every Capitol will have one, but the chances are better than looking 2 in SW iowa where there are only about 5 people per square mile.
It isn't even saying that intellegent life might not be found in other places, just if I know if I'm playing poker 4 aces would be great, but sometimes you have to work 2 pair and that is certainly better than 9 high. So I'll chose to work on the 2 pair until we know enough to have the 4 aces. Feel free to work on the 9 high if you want.
