We could find alien life but politicians don't want to, claims scientist

This is according to Seth Shostak, a senior astronomer at Seti Institute
Data suggests our galaxy has 40 billion planets with potential for life
But finding these depends on sophisticated and expensive experiments
'Sadly much of this reconnaissance hardware is still on the drawing boards, not in space,' said Dr Shostak.

Well. Yes. The truth is hard for many politicians for many reasons. Since exactly when has the absolute truth produced your next paycheck?
Yep, there is a lot that the politicians don’t wanna do. We get the government we deserve.
With people like Seth Shostak on our side, we thankfully deserve even more!

Some unsophisticated folks would think that this well known figure is implying that there are that many Earth Like planets with that many civilizations just sitting out there in our galaxy.

It is irresponsible statements such as this that cast a poor light on our endeavors in listening and looking. To my knowledge not one other Earth-like planet as yet has been found that has all of the dozen or more necessary conditions for life. Therefore such a statement as this is wildly speculative and premature. If there are any such planets with an advanced civilization such as ours they are most likely too far away for us to ever detect. A professional in the field of astronomy should know this far better than I. So I say this with the same certainty of the putative 40 billion number. Since we are UNCERTAIN to a high degree at the moment we keep searching and listening for a possibly rare event to occur--we have been doing so for 50 years now.

Those in Academia don't need to be polishing unsavory items such as this.

Agreed! And yet the point is made.

There seems to be some pre-existing scientific research backing the 40-billion-planet remark by Dr. Shostak. He specified life in general, not intelligent life. See link to article, below:

Is it just me or has some one else noticed that we occupy a VERY small space in the earth's 4.5 billion year history. I don't know how to put this in perspective, but it is a very long perspective if I can. Human civillisation on earth has been theoretically obsrvable for about the last 50 to 100 years. That's 50 to 100 of the last 4.5 billion years. If searching for intelligent life were a lottery the odds of finding it would be long in the extreme. Perhaps a civilization that has been observable for 1,000 years would be found more easily - maybe not. The odds in that case would not be much better. Finding intelligent life is similar to state lotteries in another respect - multiple drawings, or games over time. All planets in our galaxy did not come into existence 4.5 billion years ago, they are probably constantly being formed and destroyed as a natural part of stellar evolution. So this would mean another factor would be how long aliens were 'online' and when. We could miss them by a million or a billion years. I'm sure life is plentiful in the universe, but I think advanced and intelligent life is very rare.

Human civilisation on earth has been theoretically observable for about the last 50 to 100 years.

In terms of radio and TV signals you would be about right. But if an ET probe went by with an optical telescope that would be different of course. My pessimistic view is that IF there is intelligent life out there apart from bacteria, then the odds of finding it, or they us is infinitesimally small. But that doesn't mean that we shouldn't look or even advertise our presence.

Star Trek worked on the premise that the Vulcans only made themselves known when they detected the launch of the first Earth warp-powered starship. I can buy into that idea. While mankind is restricted to our own solar system there is no need for anyone outside of it to make contact, but the day we can travel further will be the time we will probably find out if they are there or not.

Frank Drake, senior scientist at the SETI Institute, responded that no alien civilization appears to be continuously broadcasting a powerful "beacon" signal from a planet circling any of the nearest 1,000 or so Sunlike stars, at least in the frequency bands we've searched. If there were such powerful beacons, they'd have been picked up by Project Phoenix, an ambitious nine-year undertaking that the SETI Institute concluded in March 2004. - /quote]

We should keep this in mind and also this:

he says, the only aliens we're likely to hear are ones intent on deliberately signaling to emerging civilizations like us.


Drake also points out at this conference (2006 time frame) that even 10 megawatt transmissions like radar etc could only be detected a few light years away.

So I (Daddio) will take the liberty of opining to say that "I think that we should try to listen at radar and TV frequencies and also start broadcasting a "We are Here" message to Nearby stars (100 light years or so)

Pragmatically Frank Drake is right. We don't know whether there are any warlike Klingons or peaceful Vulcans out there, that is the stuff of Science Fiction. But I would judge that any ET specifically advertising themselves would be doing so for likely benign reasons. But you also take the risk that others who are just looking are not so peacefully intent as we are. So I'm not sure we should advertise our presence. At least until we have developed half a chance to try to protect the world from invasion.

Scientists At SETI Have Plans To Converse With Aliens

Astronomers have always been curious for knowing whether there is a second planet like Earth where people, aliens as they are specifically termed, live. Let’s just forget significance of their ambitions but embrace this fact that scientists have devoted this semicentury for purpose of listening extra-terrestrial civilizations. All these efforts have led most of them to believe that there is no such thing as an ET.

ugh. I personally don't believe it is wise to actively attempt to signal ET's. There is a strong danger element present, and with no plan in place if the mission is a success...I just don't know if a 50/50 chance of a friendly ET encounter is a risk we as a civilization should act upon.

It is What we send that is most important. It should be a message of peace, showing the good sides of humans, our creativity and our features of caring for and loving other creatures. Most of us have that in us, naturally.

There is no danger ! There are already here and monitor nuclear plants.

it's a secret for nobody but where do they come and how it's possible government stay mute?

I'm afraid that is overly optimistic. All they have to do is sit back and watch and listen at a safe distance and discover the ugly truth about most of the people in charge and how we would likely react if they made themselves known to all.

I think it's giving these potential ET's too many human-like characteristics to assume that they would be interested in watching and studying us.

I do believe they find us a rather interesting species, Gordon, with lots of potential.

Politics??

That would be just the reason why ETI wouldn't have anything to do with us (imo).
