 In modern times, a literal reading of the ascension-stories has become problematic, due to the differences between the pre-scientific cosmology of the times of Jesus, and the scientific worldview that leaves no place for a Heaven above us.Theologian James Dunn describes the ascension as at best a puzzle and at worst an embarrassment for an age that no longer conceives of a physical Heaven located above the Earth.Similarly, in the words of McGill University's Douglas Farrow, in modern times the Ascension is seen less as the climax of the mystery of Christ than as "something of an embarrassment in the age of the telescope and the space probe," an "idea [that] conjures up an outdated cosmology."
