Time... That relentless force that transports us from what was to what will be. Though no one can say exactly what time is we do know what time it is. 5-4-3-2-1- For Millennium, this is a landmark a special moment in time. But far from all the commotion millions of others count their years very differently. For Buddhists the year 2000 came and went more than five hundred years ago. In the Muslim world it was only the year 1420. While for many Jews it's the year the date was 5760. Nevertheless the observance of this year 2000 is a singular opportunity... to listen to the heartbeat of the planet. The National Geographic Society has long been capturing time: making it stop, slowing it down, and speeding it up... All to better comprehend the relentless flow from what was to what will be.
