science proves fate?

alright, please read the whole post before flaming me Every smart person knows that the universe obbeys laws. I'm not talking about scientifical laws, as those could possibly be wrong; I'm talking about a universal law. For instance, objects with mass tend to approach each other because there is gravity. The effect of gravity is not random, it always follows a specific criteria, depending on many variables. Which means that, if two exactly identical corpses were set completely isolated, they would behave the same way, having exactly the same outcome. Of course that such a hypothesis does only work in theory, since it is impossible to completely isolate a body or to make an identical copy of it (including sub-atomical structure). The universe is led by the action-reaction rule. Actually, it is a much more complex chain of reactions followed by reactions followed by reactions.. Let's take a theoretical example: Action #1 - Reaction #1 - Reaction #2 - Reaction #3 - Reaction #4 Analysing that hypothesis, no matter when or where Action #1 happened, it would succeed into Reaction #1, then Reaction #2, then Reaction #3, and finally Reaction #4. As a rule, the outcome of Action #1 would eventually be Reaction #4. Simply because the chain of reactions is determined by the laws of the universe, and would succeed the same way. So, by knowing Action #1 happened, you can predict that Reaction #4 will happen. No matter how or when or where, that would be the outcome of Action #1. All the universe is an infinitely complex chain of actions and reactions, following a much more complicate structure. If all the universe follows the same laws, the end of the universe could be already determined at the beggining of it, as long as we know the rules. Of course, that task would be incredibly complex, and impossible to work out, even with the best computer ever made. But still, it would be possible. Applying that to our everyday lives, we can assume that everything that happens is the outcome of reaction, either on a chemical or physical level. Even our thoughts, which are the combination of several chemical reactions in our brain, would be determined by the laws of the universe. Concluding, the universe is already fully made, we are just a bunch or organised chemicals that correspond to these laws.Since the laws are applicable to every corpse, we too are just the outcome of several reactions. One may ask "what is the reason of living then, if everything that will happen will happen? If we don't have free will, what does our existance change at all" That is of course true, but think about it: the very fact that one had such assumption is the outcome of such reactions. We have the impression that we have free wil because we, too, are made of matter and work through the action-reaction chain. The final thing one may consider is that the laws of the universe change, behaving differently according to time or to the place where the matter is. The theory doesn't lose it's veracity even in such conditions. Even if the laws of the universe vary, it would still be regular: it would depend on either the time or the place where a corpse is. Which means that another corpse, displayed in the same time or place of another one, would behave in the same manner. For that, the changes in the universe's laws could be tracked, and considered. To me, these assumptions kind or scientifically prove that there is no way to change the future: it has already been determined, from its very beggining. Feels free to discuss the possibilites
