Namely, he claims 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.
