1. The document discusses similarities between subatomic and astronomical levels, noting electrons orbiting nuclei like planets orbiting stars and spherical shapes at many scales. 2. It then notes Avogadro's constant of 6.022140857(74) ×1023 mol-1, which relates the number of entities at the macro and microscopic levels. 3. Based on the similarities observed and Avogadro's constant, the author postulates that there are exactly 6.022140857(74) ×1023 stars in the universe, equivalent to 1 mole of stars.

1. “1 Universe = 1 Mole”
What I learnt from books and daily observation is Nature tries its best to keep things simple (you
kidding me) by providing a pattern so we can (try to) understand it. Over the time, human also
has learnt tremendously (but may be still very little) about nature and its properties. So far, we
have detected the presence of tiniest quarks particle (10-19 m) to biggest galaxy, IC 1101 (6
billion light years).
There is so much undeniable similarity between atomic and astronomical level. Few examples:
Electrons rotate around nucleus, the same way planets rotate around their stars.
Electrons, nucleus and all other subatomic particles spin on their axis, like all other astronomical
particles do on their axis.
From a nucleus to a water droplet to a planet, all have (almost) spherical shape.
Nucleus is power source of an atom and keeps it intact. In the same manner, a star keeps its solar
system intact. All other micro or macro particles just rotate around its nucleus.
Now, today, sitting next to this pool in this beautiful summer night and thinking about chemistry
(Yeah, I do that sometime), a particular number striked my brain so hard. This number is, as we
all know it, Avogadro’s number = 6.022140857(74) ×1023 mol−1.

2. Avogadro's constant is a scaling factor between macroscopic and microscopic (atomic scale)
observations of nature. As such, it provides the relation between other physical constants and
properties. For example, it establishes a relationship between the gas constant R and the
Boltzmann constant kB,
R = kB NA = 8.314 Jmol-1K-1
and the Faraday constant F and the elementary charge e,
F = NAe = 96485.3365 Cmol-1
The Avogadro constant also enters into the definition of the unified atomic mass unit, u,
1 u = Mu/ NA = 1.660,538,921(73) x 10-27 kg
where Mu is the molar mass constant.
Today, this number, 6.022140857(74) ×1023, is feels so magical. No matter what the physical
state of the matter is, this number is always there.
1 gram or 1 mole of Hydrogen has 6.023 x 1023 atoms.
12 gram or 1 mole of Carbon has 6.023 x 1023 atoms.
55.84 gram or 1 mole of Iron has 6.023 x 1023 atoms, and so on. Why 18 gram, 1 mole of water
has 6.023 x 1023 molecules, why not 8.023 x 1025 molecules or something else?
I read at many places over scientific websites, journals, articles, that the number of stars in the
universe might be 1022 or 1024.
Just by looking at the similarities between subatomic and astronomic levels, today, I postulate
that we have exactly 1 mole (= 6.022140857(74) ×1023) of stars in our universe.
