It tells the story of a young boy who slips off in a space ship and cruises over to a black hole, only to discover that he&#8217;s made a terrible mistake: He forgot one of Einstein&#8217;s fundamental observations, which is that time is not the same for everybody everywhere.<\/p>\n<p>[\u2026]<\/p>\n<p>Einstein&#8217;s theories posit that as one gets closer to a center of gravity, time will &#8220;slow down.&#8221; So if you spend the rest of your life closer to the Earth&#8217;s center of gravity on 34th Street while I spend the rest of my life at the top of the Empire State Building, time for you will tick a teeny, teeny bit more slowly than time for me.<\/p>\n<p>Einstein meant this not poetically, but literally. If you and I each had a watch, ticking off hundred-billionths of seconds, the watch on your wrist down below on the street would tick fewer times than the watch I was wearing up in the sky. It wouldn&#8217;t be a big difference \u2014 a few billionths of a second over 20 years \u2014 but it would be a real difference. If we decided after several decades to meet and compare watches, we&#8217;d see that they would literally differ, that time for the two of us had indeed ticked differently.<\/p><\/blockquote>\n<p>via <a href=\"http:\/\/physicsbuzz.physicscentral.com\/2008\/10\/icarus-at-edge-of-time.html\">Physics Buzz<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A Light Take On The Gravity-Time Relationship Brian Greene explains the link between gravity and time.
