This is an extremely small shift, which means that an optical clock with a precision of $10^{-18}$ could potentially detect this shift. \n\nTo detect such a small shift, the clock would need to average over a long period of time to accumulate sufficient signal-to-noise ratio. The required averaging time depends on the noise characteristics of the clock and the desired sensitivity. \n\nNext step: Estimate the required averaging time based on the clock's noise characteristics and the desired sensitivity.","model":"Qwen3-4B"}]}
