<div dir="ltr">This reminds me of the songwriter Peter Mulvey's description of a conversation he had with his friend, Vlad, the astrophysicist that begins with the question<span style="color:rgb(15,17,17);font-family:"Amazon Ember",Arial,sans-serif;font-size:14px"> 'Are there intelligent civilizations out there other than ours, and if so why haven't they contacted us?'</span><div><span style="color:rgb(15,17,17);font-family:"Amazon Ember",Arial,sans-serif;font-size:14px">You can hear this at </span><a href="https://www.petermulvey.com/media/">https://www.petermulvey.com/media/</a> (The actual conversation begins at about 2:45).</div><div><br></div><div>Same question, and same answer...... but well done.</div><div><br></div><div>-Al</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Feb 22, 2022 at 1:37 PM Carl Lazarus <<a href="mailto:carllazarus@comcast.net">carllazarus@comcast.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div lang="EN-US" style="overflow-wrap: break-word;"><div class="gmail-m_-6147063847327019349WordSection1"><p class="MsoNormal">I just played the recording of Howard Winkler’s talk “Is There Intelligent Life Anywhere in the Universe” and enjoyed it very much. (I had a conflict the day of the talk.) It surprised me, however, that nobody brought up a probability factor of how long intelligent technological civilizations last. We’ve only had the technology to transmit radio waves for 120 years or so, and even a little shorter for the ability to transmit powerful signals. How long will our technologically-capable civilization last. One hopes a long time, but perhaps we will end it before long by climate change or by nuclear war.<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">If such civilizations arise randomly after billions of years of evolution, and they wipe themselves out within a few hundred years, there might not be any others around now.<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Sorry for this depressing thought, but I’m not the first one to mention it.<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Carl Lazarus<u></u><u></u></p><p class="MsoNormal"><span lang="FR"><a href="mailto:carllazarus@comcast.net" target="_blank"><span lang="EN-US">carllazarus@comcast.net</span></a></span><u></u><u></u></p><p class="MsoNormal"><span lang="FR">617-964-7241 (H)<u></u><u></u></span></p><p class="MsoNormal"><u></u> <u></u></p></div></div>===============================================<br>
