Researchers at the University of New South Wales have developed a new type of atomic clock
that measures an atom's neutron orbit instead of the electron's flight path. This method is apparently accurate to 19 decimal places, with several lasers shifting electrons in a certain way, allowing Professor Victor Flambaum to measure the "pendulum" motion of the neutron. It's purportedly close to 100 times more precise than its predecessors -- all with no freezing involved
. These existing atomic clocks may be accurate beyond 100 million years, but for this new breed of hyper-accurate timekeeping, you'll only need to reset the clock once every 14 billion
years. And we have no idea how they calculated that.
