I am Swedish and interested.<p>There is 100-200 billion galaxies. The estimated number of stars in the universe is between 10^22 to 10^24. Each star on average has more than planet in orbit. That means its at lest 10^22 planets. 10000000000000000000000. Whats the probability we are the only one with intelligent life on it?<p>Here is a Russian billionare funding interstellar space craft. <a href="http:&#x2F;&#x2F;www.sciencemag.org&#x2F;news&#x2F;2016&#x2F;04&#x2F;russian-billionaire-unveils-big-plan-build-tiny-interstellar-spacecraft" rel="nofollow">http:&#x2F;&#x2F;www.sciencemag.org&#x2F;news&#x2F;2016&#x2F;04&#x2F;russian-billionaire-u...</a><p>We should work together in peace to discover these new planets.<p><a href="http:&#x2F;&#x2F;www.esa.int&#x2F;Our_Activities&#x2F;Space_Science&#x2F;Herschel&#x2F;How_many_stars_are_there_in_the_Universe" rel="nofollow">http:&#x2F;&#x2F;www.esa.int&#x2F;Our_Activities&#x2F;Space_Science&#x2F;Herschel&#x2F;How...</a> <a href="http:&#x2F;&#x2F;www.space.com&#x2F;25303-how-many-galaxies-are-in-the-universe.html" rel="nofollow">http:&#x2F;&#x2F;www.space.com&#x2F;25303-how-many-galaxies-are-in-the-univ...</a> <a href="http:&#x2F;&#x2F;www.skyandtelescope.com&#x2F;astronomy-resources&#x2F;how-many-stars-are-there&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.skyandtelescope.com&#x2F;astronomy-resources&#x2F;how-many-...</a>

They don&#x27;t even answer the question. I guess he suggests that Americans are still explorers and other countries aren&#x27;t. That&#x27;s hardly an explanation.

The author is misinformed.<p>Jurij Milner who is Russian, is giving an unprecedented 100 million USD for SETI purposes as part of the Breakthrough Listen project.

I&#x27;m absolutely interested in the hunt for alien life. It&#x27;s just that I don&#x27;t think SETI (looking for technological radio signals) is a good way to find it. No signal we&#x27;ve sent into space can be detected from more than half a lightyear away. Radio broadcasts lose power over distance far to quickly to be detectable over interstellar distances, unless you&#x27;re transmitting with the power of a star.<p>You could send a tight beam of course, but then you need know where to send it. Aliens have to know we&#x27;re here and they need to care enough to spend significant resource to send us a message.<p>So while I&#x27;d love to see a sign of extraterrestrial life, I don&#x27;t think searching for radio transmissions is the way to go.

Age of life on earth: ~3,800,000,000 years<p>Age of earth life knowing about electromagnetic radiation: ~217 years<p>Radio SETI will arguably only help us find a species in our relative window of technology. But I think it&#x27;s worth working on.

This feels like one of those articles where the author justifies the truth of some non-obvious &quot;fact&quot; without first showing that it is true.<p>Like is it really a thing that &quot;only Americans are interested in searching for alien life&quot; -- I am American, and I wasn&#x27;t aware (and many of my friends aren&#x27;t American).

Given the U.S. propensity for religiousity, perhaps another effort is searching the universe for God?

Maybe the rest of the world realizes it would go something like this,<p>&quot;OK found them!&quot;<p>&quot;Awesome! Yay! Hurray!&quot;<p><i>celebration for weeks, maybe months, hysterical articles, news headlines, further research initiatives, etc</i><p>Decades later, still have hunger, famine, rising global temperatures, scarce resources, disease, cancer, wars mongering superpowers, and corporate greed, etc
