You cannot have arbitrary small precision past a certain point no matter how much memory you allocate. You will run into this limit and it's a physical hard limit. Lookup why it's called quantum (mechanics, physics, field theory, etc). Before you simulate an entire universe try accurately simulating one atom. Let me know how it goes (spoiler alert: the computing power needed to do this is beyond the computing power we have today)
