Just a wild guess - the path length due to temperature and wear should grow and shrink at a slow rate, no? The gravitational wave however should be a spike, affecting the lag that could be potentially be measured.
The LIGO-lasers are probably much more precise, but we have way more fiber and clocks than LIGO observatories. Thoughts?
- analog31 10y agoThinking about it more, it was mentioned that the laser clocks might have a fair amount of phase noise, and might not be good for picking up fast time lag signals. On the other hand, you can feed multiple lasers down the same fiber, so a better experiment might be to wait for the fiber network to be built, and use a separate laser color from a specialized laser with excellent short term stability.
