Given a Universe abiding solely by deterministic laws, Laplace's reasoning seems to make perfect sense. So let us take this deterministic Universe and imagine within it a scientist to whom the, let us call it: the ultimate formula, was made accessible. So, being capable to plug this hypothetical formula into a supercomputer, all the past states of the Universe as well as the future states would be absolutely and precisely knowable to the scientist. So here's where the paradox arises: imagine the scientist uses said supercomputer to know how the next minute will play out: literally see the future. When this future is made visible to the scientist, then he is, therefore, able to act in a way that will create a different future than the formula predicted, rendering it useless in that sense.
