Given the Heisenberg uncertainty principle doesn't this mean that to observe the location of something the velocity of the something becomes more uncertain and vice versa now if the universe is deterministic then the state of something at a particular point in time should determine the future and fate of that something. If we have a complete model formed from theories about the observations we have. Given the knowledge of the state of something we should be able to calculate using the model the fate of that something and we would also be able to determine its outcome. However doesn't the the Heisenberg principle mean we can never know with any certainty the actual state of something at any particular point in time thus the information we use in the model would never be able to determine the precise outcome of anything and more over we would never be able to verify the actual future state of that something because of the uncertainty and thus we would be unable to verify the accuracy of the model. If the hiesenberg principle is correct then doesn't this mean that the pursuit of a complete accurate model is potentially unreachable because we will only be able to verify it to within degrees of certainty.
The Universe in not deterministic. Heisenberg's Uncertainty is the minimal amount of uncertaintly in any measurement. It gives rise to probabilities, which we use to lower our uncertainty. This is the best we can do.
Newton was a firm believer that IFF we knew the position and velocity of every particle in the Universe, then yes, we could determine our future and deduce our past.
Unfortunately the Heisenberg Uncertainty principle limits the amount of information we can know about a particle or a system of particles, and thus the Universe in not deterministic.
