In BriefBill Nye answers the question "Does the universe go on forever?" as part of his weekly series Tuesdays with Bill. It is worth watching for a concise answer to a question we all asked our physics teachers at school.
In a recent Tuesdays With Bill episode, part of a video series run by Big Think in which Bill Nye answers a question from the American public, an inquisitive youngster named Aaron asked, “Does the universe go on forever?”
It is a question that has haunted humanity throughout time, plaguing us with doubt about where to situate ourselves in a space without definition.
In the video, which you can watch below, Bill Nye concedes that “no one really knows the actual answer to that,” but also says that we know it is expanding due to the distance between stars increasing.
Robert Dijkgraaf, Director for the Institute for Advanced Study, has also recently made a video on the subject in which he concurs with Bill, stating, “using our satellites, we can pick up a signal that was emitted at this very brief moment after the Big Bang” to “almost see the edge of the visible universe.” However, while Dijkgraaf may not know how big the universe is, he is more certain on how it will end.
