Surface presentism is the combination of a general relativistic physics with presentist metaphysics. In this paper, we provide an argument against based on black holes. The problem focuses notion event horizon. We argue that present locations horizons are ontologically dependent future hole regions, and dependence incompatible presentism. consider five responses to available surface presentist,...

We revisit the quantum cosmological constant problem and highlight important roles played by de Sitter (dS) horizon of zero-point energy. argue that fields which are light enough to have a dS energy comparable Friedmann-Lema\^{\i}tre-Robertson-Walker (FLRW) Hubble radius main contributors dark On other hand, heavy develop nonlinearities on sub-Hubble scales cannot contribute speculate our propo...
