Abstract: | Ted Peters has emphasized the theological concept of prolepsis and a “retroactive ontology” in which God creates from the future. We consider here possible connections between prolepsis and scientific theories about transmission of signals backwards in time. After considering objections to time travel, we discuss putative means of achieving it—tachyons, “time machine” solutions of Einstein's equations, waves in dark energy, and advanced solutions of wave equations. We then reflect on ways those theoretical constructs, if realized, might be of theological interest. Applications to the resurrection of Jesus, predictive prophecy and the creation of the universe will be discussed. |
