If you have ever seen those replies that come in from <a href=\"https:\/\/www.cbsnews.com\/tag\/artificial-intelligence\/\" target=\"_blank\" rel=\"nofollow\" data-invalid-url-rewritten-http=\"\">AI, <\/a>it&#8217;s got no soul. It&#8217;s got no personality.&#8221;\u00a0<\/p>\n<p>He says the questions he gets today are more playful and imaginative.\u00a0<\/p>\n<p>&#8220;People are now asking questions that are a little more fun, rather than, &#8216;How hot is the sun?&#8217; Stuff you can just look up.&#8221;<\/p>\n<p>One example he highlights: &#8220;If aliens came and exploded the moon, what effect would that have on us?&#8221;\u00a0<\/p>\n<p>Tyson notes that while the moon might not be crucial now, it may have helped early life by creating isolated tide pools. &#8220;Without the moon, astronomers would be very happy, because the sky would be dark all the time,&#8221; he said.<\/p>\n<h2>Likelihood of life elsewhere<\/h2>\n<p>On the topic of aliens, Tyson is clear about the science and the skepticism.\u00a0<\/p>\n<p>&#8220;Everyone that studied the question of life in the universe\u2026 would not deny the likelihood of life elsewhere,&#8221; he said. But he doubts they have visited Earth.\u00a0<\/p>\n<p>&#8220;We all grew up when no one had cameras, so everything was an eyewitness testimony. Everybody has got a high resolution camera video, and nobody&#8217;s got some alien walking off their flying saucer.&#8221;<\/p>\n<p>The book also dives into quirky scientific curiosities, like how leap years actually work.\u00a0<\/p>\n<p>&#8220;So someone said, &#8216;How accurate is the leap year correction?&#8217; Because one day every four years, you have a leap day. Turns out, that over corrects. So every 100 years, you have to take away a leap day that would otherwise be there. And that under corrects. Now you have to add a leap day back every 400 years to correct for the other two leap days.&#8221;<\/p>\n<p>He even addresses the famous &#8220;Superman&#8221; scene where reversing Earth&#8217;s rotation supposedly turns back time. Tyson&#8217;s verdict is blunt: impossible.\u00a0<\/p>\n<p>&#8220;Your time is not linked to the rotation of the Earth, they have nothing to do with each other,&#8221; he explained. &#8220;But if he did that, the oceans, which are not attached to the Earth, would have kept moving &#8230; he would have killed a billion people in North and South America.&#8221;<\/p>\n<p>His brother, an artist, did the illustrations for the book.<\/p>\n<p>&#8220;It&#8217;s a romp through the universe, celebrating people&#8217;s curiosity,&#8221; Tyson said.<\/p>\n<p><em>&#8220;Just Visiting This Planet, Revised
