The law is related to the idea of the arrow of time that posits the one-way direction of time: from the past to the futureSTATION GOSSIPhttp://www.blogger.com/profile/14290129071922737076noreply@blogger.comBlogger2125tag:blogger.com,1999:blog-3188088343643315521.post-92121104448709756962019-12-30T21:53:50.958-08:002019-12-30T21:53:50.958-08:00Nobody's been back?

In the past it was witches who rode broomsticks but this is the 21st century. We got time travel!<br /><br />Nobody's come back from the future. And you can't say the future hasn't happened yet because if time travel exists, so must the future have happened; that is, if in one thousand years time somebody came back to hear you say, "The future hasn't happened yet", then the future has to have happened. But nobody's been back.STATION GOSSIPhttps://www.blogger.com/profile/14290129071922737076noreply@blogger.com
