My limited knowledge of the Anti-life equation is only how I imagine it relates to the idea of a unified Life equation, which, theoretically, would predict any and every motion in the universe once provided the exact data.
How science views the universe right now is that uncertainty is literally built into the smallest particles, meaning that they are, by definition, unpredictable, as the act of viewing them changes their activity. Thus, even if you were able to provide a hypercomputer with the size, trajectory, energy, etc. of every particle in the universe, it still would not be able to perfectly predict outcomes, due to tiny uncertainties.
Think Jeff Goldblum's speech from Jurassic Park.
If, in the future, that view were changed, and we could find that underneath the uncertain electrons and quarks, there existed a singular entity (or set of entities) that we could predict with a simple set of algorithms, then the universe could then be said to be 'certain.'
In this hypothetical scifi world, if you could feed all available data about the universe into a hypercomputer, and run it through the exact 'equation' predicting the movement of universal particles, this hypothetical computer could then accurately feed out the exact movement of every particle in the universe for years until outside interference made the predictions uncertain. (These all-encompassing hypercomputers seem to exist in cosmic DC)
But if the universe were not infinite in size, and if somehow a set of sensors could quantify the position of every particle in the universe, this equation that someone fed into a hypercomputer could, with complete accuracy, predict 'every single event from that point until the end of time.'
Now while you could not change that future, having access to that kind of information would give you access to an ungodly amount of power
