How can you when there is no option but to run into the problem of infinity?
No matter how much you zoom into an object it is always logically possible to zoom into it further.
Any object will have a real ultimate length but it may not be possible to measure it with absolute accuracy
What you have to do is to show to me that ultimate reality, such as ultimate dimensions of an object, can be sensed
and not merely imagined
Do you know the difference between sensation and imagination?
When you see, with your own eyes, an apple on a table, that is sensation.
When you imagine in your head an apple on a table, that is imagination.
When you imagine there is an apple on a table, that is projected imagination.
Projected imagination can be a random guess, or a guess based on personal preference, but it can also be an educated guess, which is a guess based on experience.
Whatever its from, imagination can never be anything more than imagination. It can never become sensation.
This is where language can confuse us.
In everyday parlance, the word reality is used to refer to BOTH what is sensed and what is not sensed but is imagined based on experience.
We say "there is a tree in our backyard" both when we are looking at it and when we are not looking at it but can expect it to be there based on our prior observations.
When one and the same word is associated with two distinct concepts, one must be careful not to conflate the concepts.
Senses and intellect are not equal.
Senses are fundamental.
Though predictions must refer to some sensory event in time, theoretical constructs need not. They can be as imaginary as you want them to be.
If you want to believe that every event in the universe is determined by some supreme being, that is fine, so as long you admit that it's nothing more than imagination (that is not projected and that is thus without implications and beyond testing.)
The problem begins when you confuse theoretical constructs with reality.
When you fail to understand that things such as ultimate objects (or objects-in-themselves), causality, laws, etc are theoretical constructs and not reality itself.
