Please do watch it.
Minimum two things are required to describe anything. Because one of it is taken the reference to say that this is not the same object as other. This is perhaps the fundamental principle, which we humans are limited by.
Why do I say minimum two things? I have written it on article: http://bioinsilico.blogspot.in/2015/03/intelligence-and-in-search-of.html
Minimum two different things are required to describe anything.
To reach this conclusion, let's find out what we see or know. We know things by knowing their shapes. But how to know the shape of a particular object. For it, we have to know the distance (the way of arrangement of the object). But again the question arises, how we know the distance. What makes us aware of the distance?
Let's take an example of colored board problem.
Imagine a one red colored board. Also, imagine we are only seeing it and nothing else. Can we distinguish anything from it? We only see red and nothing else. Take an analogy of a person with eyes closed. When he/she enters the room, he/she can't distinguish between a chair, a table, a bed. He/she even can't say the particular object exists or not.
Now come again to the colored board problem. Now another big black color circle comes on the board. But how do we know it, it's a circle, not a square? To know it we should be aware of distance. With using distance, we can tell whether it's a circle or square. It's because we have a tendency to measure distance, we can distinguish between a square and circle.
But how does distance arises in our mind?
We measure distance by counting. But how do we do counting here? We can only say that red is different from black. We can't count anything in it. How the numbers are so intuitive in our brain. We can't count a number of red dots on the board, neither we can count the number of black dots (circle) on the board.
So there is something that makes us count. It's a reference. The SMALLEST reference.
Imagine a smallest black dot in the board, surrounded by red color. Now take it (the smallest black dot) as the reference.
Now we are ready to say whether the black one is a circle or a square by counting. Just start putting the smallest reference black dots in the black circle line by line and measure no. of dots in each line. The first line would have one dot. The second line would have two dots, third 3 dots and at diameter maximum number of dots, then when we go down, the dots decreases and reaches to one again.
Bingo.. we know counting now.
Perhaps our limitation is based on this principle.
The matter is quantized as there is a demarcation between two objects, i.e. we can distinguish between objects but space is not as there is no demarcation is space.
Oops, we can demarcate space with matter. But as space is only one (i.e. very huge), it won't possible for matter particles to demarcate it if we take complete universe...
