If the cosmos has a reflective boundary beyond redshift 15, gravitational waves from repeated black hole mergers could reveal it, with a TianQin+LISA network best at fixing the boundary's orientation.

abstract
The idea of gravity as an "emergent" phenomenon has gained popularity in recent years. I discuss some of the obstacles that any such model must overcome in order to agree with the observational underpinnings of general relativity.

Gravitational waves and cosmic boundary
If the cosmos has a reflective boundary beyond redshift 15, gravitational waves from repeated black hole mergers could reveal it, with a TianQin+LISA network best at fixing the boundary's orientation.
