That's Not Mathematics

Once you set a function to zero, it has to remain that way. Otherwise you are breaking the rules of mathematics.

I already responded to you about the traffic jams. It is known that traffic jams obey the mathematics of hypersonic flow. There are no delta functions in such flows of cars or anything else because infinity does not exist physically.

The delta function is a mathematical invention that approximates, for example, the location of an electron at a point. But electrons do not exist at points, just because it would have infinite mass and charge density at that point, which is physically impossible.

So there is no way to represent a delta function with anything that exists. Delta functions are no more than a mathematical concept.
