The theory of everything set out on this site explains from first principles, precisely this.

That numbers are physical constants should come as no surprise, for the reasons outlined in this chapter of *Trick or Treat, The Mysterious Connection Between Physics and Mathematics* published by Springer in 2016, titled ‘Cognitive Science and the Connection Between Physics and Mathematics‘.

Abstract

“The human mind is endowed with innate primordial perceptions such as space, distance, motion, change, flow of time, matter. The field of cognitive science argues that the abstract concepts of mathematics are not Platonic, but are built in the brain from these primordial perceptions, using what are known as conceptual metaphors. Known cognitive mechanisms give rise to the extremely precise and logical language of mathematics. Thus all of the vastness of mathematics, with its beautiful theorems, is human mathematics. It resides in the mind, and is not ‘out there’. Physics is an experimental science in which results of experiments are described in terms of concrete concepts—these concepts are also built from our primordial perceptions. The goal of theoretical physics is to describe the experimentally observed regularity of the physical world in an unambiguous, precise and logical manner. To do so, the brain resorts to the well-defined abstract concepts which the mind has metaphored from our primordial perceptions. Since both the concrete and the abstract are derived from the primordial, the connection between physics and mathematics is not mysterious, but natural. This connection is established in the human brain, where a small subset of the vast human mathematics is cognitively fitted to describe the regularity of the universe. Theoretical physics should be thought of as a branch of mathematics, whose axioms are motivated by observations of the physical world. We use the example of quantum theory to demonstrate the all too human nature of the physics-mathematics connection: it is at times frail, and imperfect. Our resistance to take this imperfection sufficiently seriously (since no known experiment violates quantum theory) shows the fundamental importance of experiments in physics. This is unlike in mathematics, the goal there being to search for logical and elegant relations amongst abstract concepts which the mind creates”.

The mathematical equation 1a + 2a = 3a describes a mathematical law of quantitative relationships. It also describes a physical absolute, according to the law of conservation of energy. Numbers and numerical relationships are not merely abstract concepts, they are developed from the same fundamental principles as physical laws. This is not insignificant, it suggests that the physical universe developed according to natural constraints which are purely mathematical.

If we expect advanced aliens to know the natural number sequence then humans didn’t invent numbers, we discovered them.

If numbers are a human discovery then so are their mathematical relationships.

If mathematical relationships are discoveries not inventions then they’re natural laws.

1+2=3 is a natural law.

This is not insignificant.

nothing can be created or destroyed, which makes 1a+1a=2a an entirely natural law

if you place an object (a) with an identical object (a), together they form a group (a+a)

the ratio of the quantity of a in (a) to the quantity of a in (a+a) is

a:a+a

the ratio of the mass of (a) to the mass of (a+a) is

a:a+a

the physical ratio

a:a+a

is precisely identical to the numerical ratio

1:1+1

the physical ratio

a:a+a

is precisely identical to the numerical ratio

1:2

so

a:a+a = 1:2

human number theory and natural physical laws are based on precisely identical principles

⚫ and ⚫⚫ makes ⚫⚫⚫ (physical quantity)

1 + 2 = 3 (human number)

each of the ‘equations’ describes the same relationship; each is based on the same principles

each expresses inviolable laws which govern the combination of identical entities into groups

*natural numbers are physical constants*

⚫ and ⚫⚫ makes ⚫⚫⚫ (physical quantity)

1 + 2 = 3 (human number)

each of the ‘equations’ describes precisely the same relationship

there is a single ‘sum total of everything which exists’

any multiverses exist only as subdivisions of the sum total

so we will call the single, sum total of everything which exists ‘Existence’, capitalised to indicate its status

we will give Existence the symbol ‘X’

by definition, there can only be a single Existence

but, interestingly, we can also define a primary integer quantity

there is a single ‘sum total of everything’

one ‘Existence’

X=1

so in the formulation X = 1, we are in fact defining the value of the human number 1 as ‘the quantity of Existence’
