The Age of the Universe
Religious views and scientific theories Edit
His works frequently cite Talmudic, Midrashic and medieval commentaries on Biblical creation accounts, such as commentaries written by the Jewish philosopher Nachmanides.
Among other things, Schroeder attempts to reconcile a six-day creation as described in Genesis with the scientific evidence that the world is billions of years old using the idea that the perceived flow of time for a given event in an expanding universe varies with the observer’s perspective of that event.
He attempts to reconcile the two perspectives numerically, calculating the effect of the stretching of space-time, based on Einstein’s general relativity.[7]
Namely, that from the perspective of the point of origin of the Big Bang, according to Einstein’s equations of the ‘stretching factor’, time dilates by a factor of roughly 1,000,000,000,000, meaning one trillion days on earth would appear to pass as one day from that point, due to the stretching of space.
When applied to the estimated age of the universe at 13.8 billion years, from the perspective of the point of origin, the universe today would appear to have just begun its sixth day of existence, or if the universe is 15 billion years old from the perspective of earth, it would appear to have just completed its sixth day.[8]
Antony Flew, an academic philosopher who promoted atheism for most of his adult life indicated that the arguments of Gerald Schroeder had influenced his decision to become a deist.[9][10]
His theories to reconcile faith and science have drawn some criticism from both religious and non-religious scientists, and his works remain controversial in scientific circles.[11][12]
