I&#x27;m especially interested in the AGIS proposal by the group at Stanford ( http://arxiv.org/abs/0806.2125 ). Also, is it obvious how one could use an ultra precise clock to see evidence for GWs? Such clock can reveal spatial gradients in the rate of ticks (and so reveal things like local mass densities), but GWs should be spatially homogeneous, no? Thanks for any help!</p><p><a href="https://hackerpaper.kaipfister.de/p/0806.2125/">Paper and discussion history</a>. A mention is not an endorsement.</p>gr-qc
