How long after the big bang before this clock could have existed? More than 100 ms I'll wager. :-) On Mon, Mar 5, 2018 at 8:10 PM, Eugene Salamin via math-fun < math-fun@mailman.xmission.com> wrote:

Clock consists of 10,000 Sr atoms in an optical lattice cooled to 15 nK. If this clock had been started at the big bang, it would today be off by 100 ms.
