The theory of everything in man

I have a theory.

I came across a pair of pictures, one of which is a picture of the galaxies of the universe. In the second picture, the neural networks of the human brain. And the images looked similar in structure.

Now let's get to the actual theory:

Since the universe seems to continue outward into space infinitely, and there is no end in sight, but also within man into inner space, behind cells, dna, atoms, quarks, smaller and smaller particles, the ever-shrinking inner space also seems to continue to infinity.

So at what point do these two elements - outer space and inner space - meet each other?

And turn out to be one and the same thing?

If the structure of the universe, and we humans at the center of it, turned out to be shaped like this, this would explain everything.

This would give life a real purpose. What to aim for.

We humans could start to become "enlightened" like Buddha, knowing that billions of universes that continue to infinity are constantly influencing us. But at the same time, we would be aware that all the outer space around us, the galaxies, the many universes that are already known to be countless, also contains all the same small particles inside us.

In this case, inner space and outer space would merge in us humans.

We would become Me.

Universes in Us.

Ps. Maybe this theory is just a theory, maybe not?
Because science cannot (yet) at least prove the theory wrong.
Because we don't know until when, and how, the inner and outer space around us ends.

And in this theory, the spaces never end, but continue forever, through us humans, merging into one another as an endless continuum.
