The world you live in, is an APPROXIMATION!

The physical world we live in is highly approximate. Consider the definition of a point in space: "a point is a physical entity which has no length, breadth and height but has existence only".

Can a point have a fourth dimension, like time? may be. But how do we justify this? Will a point travel in time? No it cannot. Since it does not have length, breadth or height, it cannot have physical properties that characterize other things, e.g. can point characterize temperature? No. So point is just an existential quantity in space, not time.

Consider the definition of a physical object:
"an entity that can be perceived by human beings in one or more of their visual or auditory senses".
This means a physical object will have existence as well as stability or volatility across space and time.

Now the connection between a point and a physical object which hints at the subtle but highly approximate definition of the physical world. This theory of approximation is demonstrated by the fact that physical objects can be considered an assembly of points and point does not have any dimensions: no length, breadth and height, only existence; then how do physical objects have dimentions? This is a contradiction which can only be supported by the fact that the objects themselves are approximations and points do have dimensions. Because, if it was not true, then, the following will always be true:
0+ 0+ 0+ 0 = 0 always. No physical object that we see around us can have dimensions.
Hence the universe and its contained physical objects are merely approximation of a bigger assumption that dimensions are inherent to entities around us.
