However, they did not detect any signal consistent with dark matter. One of the major problems of optical atomic clocks is that they can currently only operate continuously for about a day ...

But now some scientists are hoping atomic clocks, the most precise timekeepers ever made, could be used to help explain this elusive phenomenon. Many physicists believe dark matter is an invisible ...
