Abstract
In astrophysics, where typically phenomena cannot be reproduced in laboratory, the adoption of models and simulations becomes mandatory. Here, we investigate the modalities implied in astrophysical modeling practices by taking into account different levels of abstraction or generality at which phenomena can be framed. To this aim, we analyze two case studies involving modeling gravity at different regimes: namely, gravity at the solar system level and gravity at the cosmological level. At first glance, modeling practices and implied modalities could appear significantly different in these cases. On the contrary, by framing the analysis in terms of the how-possibly/how-actually distinction (as in Bokulich (2014)) we show that, in both cases, we can identify a web of nested modalities arranged across different levels. On this basis, we argue that, independently from the gravitational regime, there is not necessarily a direct correspondence between the degree of possibility and the level of detail at which the phenomena are considered.
