See, I get that. I just haven't seen any evidence of anyone actually being able to divine the future. I also do not think it is possible this way, only with mathematics, and that can only go so far, as I do not think it can define human behavior.
The future is entirely predictable. Completely and utterly. Because of cause and effect. There's no mystery
You predict the future all the time. For example you buy food each week because you know in the future you will eat what you have left and require more. Its obvious you need more. Your body needs fuel, it will need more fuel. You'll need more food. Completely predictable.
The problem with predicting the future is when the variables start to increase in number and depend upon each other. Lets say you want to know who will win a baseball game. The weather is reasonably predictable but you don't know how that will effect a game. You don't know if one of the pitchers is carrying an injury or feels ill. You don't know if the referee will make a bad call. You don't know if the batsman is worrying about his divorce. And you don't know how all these things will effect the performance of the players to predict the score. But if you knew absolutely every factor, you'd be able to predict the future. You could assign numbers to everything and get a cold hard completely accurate score.
But we don't know all those little factors or how to express them. The best model we have is chaos theory, but frankly we aren't very good at it. We can't use it for accuracy.
Isaac Newton was obsessed with this. He believed he could predict the end of the earth using mathematics. After much messing about he decided the earth would end in 2060. For me it probably will. I'll be 82.
How did Newton arrive at the date 2060?
This did not involve the use of anything as complicated as calculus, which he invented, but rather simple arithmetic that could be performed by a child. Beginning in the 1670s and continuing to the end of his life in 1727, Newton considered several commencement dates for the formal institution of the apostate, imperial Church. Earlier commencement dates include 607 and 609 A.D. As Newton grew older, he pushed the time of the end further and further into the future. In Yahuda MS 7 Newton twice gives 800 A.D. for the beginning of "the Pope's supremacy". The year 800 is a significant one in history, as it is the year Charlemagne was crowned emperor of Rome in the west by Pope Leo III at St. Peter's in Rome. Since Newton believed that the 1260 years corresponded to the duration of the corruption of the Church, he added 1260 to 800 A.D. and arrived at the date 2060 for the "fall of Babylon" or cessation of the apostate Church. It seems that Newton believed the fall could perhaps begin somewhat before the end of the 1260-year period and continue for a short time afterward. Whatever the precise chronology, Newton believed that sometime shortly after the fall of the corrupt (Trinitarian, Catholic) Church, Christ would return and set up a 1000-year Kingdom of God on earth. On page 144 of his Observations (1733), Newton cited Daniel 7:26-27 as evidence of this:
But the judgment shall sit, and they shall take away his dominion to consume and to destroy it unto the end. And the kingdom and dominion, and the greatness of the kingdom under the whole heaven, shall be given to the people of the saints of the most High, whose kingdom is an everlasting kingdom, and all dominions shall serve and obey him.
Newton espoused a premillenarian eschatology and thus held that Christ would return to earth to establish the Millennium.
Of course this is the same guy that thought he could turn lead into gold with alchemy, the same guy that burnt his parents house down deliberately as a child and of course the same guy that came up with that ridiculous theory called gravity that all you round earthers love so much.
