I just want to add something about how sensitive LIGO is. The gravity waves it is detecting are equivalent to measuring the distance from Earth to Alpha Centauri with a variation the width of a human hair.
Anyway, these techniques are aimed at detecting different types of gravitational waves, not necessarily about simply increasing sensitivity. I don't know what dictates the frequency of a gravitational wave.
Truth be told, I still don't get what expanding space or gravitational waves really are but then again I'm just an idiot who doesn't understand tractor calculus [1].

- strangattractor 2y agoIf one takes the width of the plow or seeder one is tractoring and divide the length of the field by that width one will get the number of times the tractor goes back and forth across the field to completely seed or plow it. If the tractor travels at constant velocity V_tractor m/s and multiplies by the width of the plow or seeder and the time in seconds the tractor took to plow or seed the field one gets the total area of the field expressed in meters^2. This can be extended to a tractor traveling at V(t) if infinitesimal units dt of area are summed. This is known as the Fundamental Theorem of Tractor Calculus and is the basis of Tractor Field Theory;)
