Abstract
Eternalism, the thesis that past and future entities exist in the same way as present ones, is a natural philosophical interpretation of special relativity and general relativity. However, these two theories are not fundamental, and several approaches aim to develop a more fundamental theory of quantum gravity, unifying all our knowledge obtained through relativistic and quantum physics. Some of these approaches imply that time is not fundamental. If time is not fundamental, what consequences can we draw from this for eternalism and the debate in metaphysics about existence in time? I will argue that the possible non-fundamentality of time, as encountered in string theory and loop quantum gravity, leads to standard eternalism or atemporal eternalism, a new position faithful to the spirit of standard eternalism.
