Yup. Well, if that's all the digits you need. It's kind of where Far UV turns into Extreme UV. That's still shockingly low energy for a nuclear decay, which is where the idea came from.

Like I said on the crosspost, reaching the frequency isn't the problem, per se. This works exactly because there's electron-transition-based lasers that can pump it. The direct link to the strong/weak force and more compact, potentially solid state clocks with better-than-atomic precision are the benefits.

I'm hoping I can eventually buy a pair of stopwatches that can measure the time dilation just from me walking around. Detecting dark matter is also cool, as is better wireless technologies.

Time is relative. Maybe if you get a clock like this you can prove it.
