The ideal weighing box thought experiment and gravitational shielding

Spacetime going through a double slit experiment and the superposition of spacetime is the main thought experiment in quantum gravity. But can a simpler and non-quantum thought experiment with a box tell us more about the true nature of gravity? Can this thought experiment be performed in an approximated way? Is there partial gravitational shielding when energy can be absorbed from a gravitational wave?

Dark Energy from Cosmological Energy Conservation

The value of the gravitational wave energy density is unknown. Current progress in gravitational wave detection suggests that the energy density of the stochastic gravitational wave background (SGWB) will be estimated in the next decades. We present a derivation of its value under the assumption that energy lost due to cosmic redshift is fully responsible for the energy gained by the cosmological constant in the expanding universe.
