As a result of my proximity, I often got to watch him in action. His kindness and passion combined with his truly impressive oratory about science, were inspirational. I thought I&#039;d share just one insight from Dr Tyson, an insight that ties in nicely with the &quot;elements of the periodic table&quot; series that I share on this blog every Friday morning. In this video clip, Dr Tyson explains one of his &quot;disturbing thoughts&quot; that might keep his audience awake at night: are we alone in the universe?&lt;/p&gt;&lt;p&gt;  &lt;/p&gt;&lt;p&gt;  &lt;/p&gt;&lt;p&gt;Would you like to watch the entire presentation? (If you wish to go directly to Dr Tyson&#039;s talk, skip ahead to 15:30): &lt;/p&gt;&lt;p&gt;  &lt;/p&gt;&lt;p&gt;Would you like to learn more about Dr Tyson?
