The Nature of Humans. The Space Needed for One Human Being in the Observable Universe.
Question
If a human could become the same density of atoms per cubic metre as the observable universe what volume would that human occupy and how many humans would fit into the observable universe at that same atomic density ?
Observable Universe
The volume of the observable universe is 4e+80 m3

Normal Matter
The observable universe has a 4e+80 atoms in it.
Source: https://en.wikipedia.org/wiki/Shannon_number
Source: https://www.quora.com/How-many-particles-are-there-in-the-universe
This allows for the observable universe to have 1 atom per m3.

Dark Matter and Dark Energy
According to the standard model of cosmology the total mass–energy of the universe contains
4.9% ordinary matter, 26.8% dark matter, 68.3% dark energy

However the nature or amount of dark matter and dark energy is unknown and so only the normal matter is considered in this essay.
Human
Allowing for an average human of 70kg.
The density of a human body is approx. 1020 kg/m3
This gives a 70 kg human has a volume of 0.06 m3.
This is approx. 1/16th of a cubic metre.
A 70 kg human body has approx. 7e+27atoms in it.

The number of atoms in a human of 1 cubic metre volume would be 7e+27 x 16
Therefore at the same volume scale as the observable universe a human would have 1.162e+29 atoms per m3.
Conclusion
The volume of the observable universe at 4e+80 m3 can accommodate 1 atom per m3.
The equivalent; 1 m3; volume of a human accommodates 1.162e+29 atoms per m3.
Therefore the existing universe would have to be 1.162e+29 times larger than it is to accommodate just 1 human at the same density of atoms; 1 atom per m3.
To accommodate the current population of the Earth; 7,000,000,000 the existing the universe would have to be 8.134e+38 times larger than it is to accommodate all of the humans at the same density of atoms; 1 atom per m3.
These conclusions lead to several further issues.
The observable universe is a depletion system. It is trying to reach a zero energy, stable density, level by allowing interaction at an energy, sub-atomic and atomic level.
The universe is variable in energy and atomic density to allow humans to exist. There are therefore limited locations where the energy, atomic density, can evolve to a life form density level and have sufficient environment, energy and resources around it to perpetuate the life at the same density levels indefinitely.
Humans have limited environment, energy and resources around them that will decrease exponentially as their population increases.
If humans venture into space and colonize other planets the depletion problem will repeat itself.
If humans solve the problem of travel through the enormous distances of space to other planets then they will encounter the relative time problem. Any planet they reach will have evolved at the same rate as the Earth and consequently will have a limited time in which to exist to allow humans to exist on it and mine it for resources.
Humans are destined to be hunter gatherers in the universe.
Wherever they go they are destined to exist on limited environment, resources and energy in a depletion condition.
They are a part of the depletion system; the singularity, expanding singularity, observable universe; trying to get to a zero energy, stable density, level.
