Table-Top Test of Quantum Gravity: Response to Sabine Hossenfelder's Critique

In response to the critique of Sabine Hossenfelder I would like to make the following comments that hopefully clarify the motivation and the analysis behindÂ our paper.

1) It is incorrect that we assume that the centre of mass degree of freedom is given as a linear (or any other) sum of momenta of individual constituents. We do not need to make any such assumption. The centre of mass degree of freedom of...
