I dare say that anything is possible.. Now.. to state my true opinion on the matter... Well I don't believe much of what I hear on the tele.. What I'm trying to say is that I am not even sure that this so-called planet has been found.

This is an interesting question. Because you put the article w/it & you didnt give your opinions.

The article is interesting. It will be neat to see what is found out if we are still alive when the technology is invented.

I am a para-librarian at a college library & I just read an article in a science journal. It was about methane gas found on Mars & Titan. Some scientists are wondering if that could mean there was bacteria?

But to answer your question... Do I believe there is life? No, I dont believe. But I do think anything is possible:)

edit: I should have stated "many things are possible"

Also, I saw another article on BBC about this planet today. But there is another problem I didnt think of earlier. This planet is so... far away that anything scientists see in the telescopes are from millions.... of years ago. It is cool that the planet has been found. New discoveries are exciting for scientists. Which is why it seems silly to focus on what hasnt been discovered (life on the planet) vs. what has been discovered (the Planet:)

I saw that - when do I leave?? We got almost a 50/50 chance someone is there -

Intelligent life happened here, yes, and there are zillions of planets like ours out there. Yes, if p is the probability that life evolved on earth and N = zillions then Np is the expected number of planets like ours with life on them, and so e^−Np = tinynumber is the probability that none of these other planets have intelligent life. The problem is the implicit assumption involved about p - that because there is intelligent life on earth p can't be too small. However all that really matters is that intelligent life evolved in the universe at least once - which of the zillions of actual earth-like planets we happen to find ourself on is irrelevant. So p, the probability of life evolving on any one of these planets (including earth) could be very very tiny, and Np could be about 1. It's like the person who wins a big lottery falsely concluding that because he won, and so many people bought tickets, there must be many others who won, because if the chance of winning was too tiny we wouldn't have won in the first place. So what is the probability of intelligent life elsewhere in the Universe (given that there it exists at least in one place)? It is simply the conditonal Poisson probability (i.e. P(X >= 2jX >= 1)) given by: (1 − e^−l − e^−l)/(1 − e^−l) where = Np. Of course this can vary from 1 to 0 depending on . For example;
if Np = 1 then the probability of intelligent life elsewhere in the Universe would be
(1 − 2e^−1)/(1 − e^−1) = 42%

42% are good odds.

I am not sure what I believe about this particular planet, but I absolutely do believe that there are other planets that support intelligent life, and that there is intelligent life out there. When we might have the technology to find them, is another question. I think the possibility is very good, to say the least, that they have already found us. But our society as a whole is not ready for them. We would be afraid of them, whether our fear was warranted or not, and we would be a serious threat to them, so they would be probably just be waiting, and observing, until we are ready. *sm*

Ok. That is stupid. So they found a planet close enough to support life. How are they gonna get there to find out? I don't believe in aliens and I think they are never going to find a planet with life. So it has the condition to have life but that doesnt mean there is. God wouldve had to put life there. People do not evolve. We did not come from pond scum or monkeys so I do Not believe there is life on that planet

Gene is correct. We don't know a whole lot about this planet. But it has the best chance of harboring life because it orbits at the right distance for liquid water and is relatively small.

And bladdecrimson, what do YOU know about astronomy? I am a nerd, at least. I have knowledge. I know that astronomers don't just look through telescopes out of the Orion catalog! They use radio telescopes, redshift, blueshift, and GIGANTIC reflector telescopes.

Probably not. All we know is that it's the same temperature as earth and the gravity is twice ours. We don't know if it's a gas giant, if it has an atmosphere ... we know nothing but the temp and the fact that it's 5 earth masses. It may even have one face pointing towards it's sun all the time. It's really close to the red dwarf.

Difficult to say, according to what i read, there are some similarities to our world.
It is a bit myopic to believe we have the only planet that has life on it.

It is hard to say at this point. When they say life, that is not saying the same thing as intelligent life. Bacteria? Don't know. It will be interesting to watch the discovery.

no, this is fantasy, the light in a telescope doesnt provide enough information to determine all the things they say, its a lie!
