Is it better to study an image pixel by pixel or by looking at the whole picture?
We deal with this question in Quantum Gravity when we decide if discrete or continuous geometry approaches are more suitable (or even more fundamental) to study a determined problem.
In our new paper, we reproduce the same computation in both types of approaches to obtain the so-called massive BMS character. Roughly speaking, this describes how the symmetries of spacetime are affected by the presence of a massive particle.
