“Our aim is that we’ll have a clock that, during the entire age of the universe, would not have lost a second.”
Maybe its because we don’t understand time, that we keep trying to measure it more accurately. But that desire to pin down the elusive ticking of the clock may soon be the undoing of time as we know it: The next generation of clocks will not tell time in a way that most people understand. The new clock will keep perfect time for 5 billion years.
“My own personal opinion is that time is a human construct,” says Tom O’Brian. O’Brian has thought a lot about this over the years. He is America’s official timekeeper at the National Institute of Standards and Technology in Boulder, Colorado.
To him, days, hours, minutes and seconds are a way for humanity to “put some order in this very fascinating and complex universe around us.”via npr
