Gödelian time-travel and anthropic cosmology

Research output: Contribution to journalArticlepeer-review

Abstract

This paper looks at Kurt Gödel's causally-pathological cosmological models (derived from general relativity), in the light of anthropic explanations. If a Gödelian world is a possible world, could anthropic reasoning shed any light on whether or not our world is Gödelian? This paper argues that while there are some good anthropic reasons why our world ought to be Gödelian, too many observations suggest that our world can?t possibly be Gödelian in fact. If Gödel's world is a possible one, anthropic teleology alone cannot explain why it isn?t the world we inhabit. Furthermore, if our world were Gödelian, anthropic arguments against the existence of extraterrestrial intelligences would imply a bleak human future. En route, some general objections to relativistic causal pathologies are addressed and some anthropic arguments to the effect that Gödelian worlds couldn?t sustain life are also addressed and dismissed.
