Abstract
Our best cosmological model, the LCDM model, predicts that in a finite time all unbound systems will cross a cosmic event horizon, meaning that no new empirical data can ever be gathered.
The Universe has already entered this phase, in which cosmological sources of information are progressively disappearing.
This prospect shows that the dependence of Bird's epistemic and Dellsén's noetic accounts of scientific progress on continuing empirical input is not merely a definitional feature of conditional accounts, but a boundary that cosmology itself guarantees will be reached.
This paper is not revisionary: it does not alter these accounts, but clarifies their scope by situating them within this cosmologically mandated regime.
As an outlook, I sketch a general account of scientific progress grounded in structural understanding, which could preserve a notion of progress even once observation is no longer possible—while leaving open the further question of whether progress ought in fact to continue under such conditions.
