And why does the observer get an erroneous answer if he makes a mistake in that physical calculation? The biggest question of all, without matter and the laws that govern how it interacts how does Plato determine the difference between a correct calculation and a incorrect calculation? I know its against your nature but when answering these questions please don't start talking about the term "definition” because that is a human invention that can not magically conjure things into existence. And you need to explain why out of the infinite number of possible definitions there is something special about the particular one that you picked that has nothing to do with physics. We’ve known for more than a century that with p-adic numbers there are an infinite number of ways arithmetic could work and all of them are logically consistent, but they all give radically different answers from the arithmetic we find most useful in our physical world. For example, in 10-adic arithmetic the numbers 4739 and 5739 differ by only one part in a thousand and 72,694,473 and 82,694,473 differ by only one part in 10 million. But p-adic arithmetic won’t help you much if you’re trying to figure out how fast a ball rolling down an inclined plane will go.
