Interesting . I peeked at my Amazon purchase library and , indeed , the number of purchases on Amazon fell off a cliff a little more than two years ago . I haven ' t purchased anything on Amazon all year . <| sep |> I disagree . It ' s pretty clear that the fall of the numbers in a lottery aren ' t actually random , they ' re just incalculable , which isn ' t the same thing . They will vary but not in a truly random way , rather they vary based on the ambient temperature , the order the balls fall in , micro differences in weight , density , surface perturbations , and maybe hundreds of other factors , many we possibly can ' t even identify and we certainly couldn ' t calculate them . However , having seen it occur and then rolling time itself back to the starting point , they will fall the same way again the next time IMO .
