Size of an atom?

One theory about the "Big Bang" I keep hearing lately is that the
Universe was condensed to the size of an atom before it exploded. Now
I'm no expert but how can anyone theorize about that size? Just curious.

And the size of an atom compared to what, considering that nothing
else existed at that point?

One cubic light year = 8.467e47 m3
Volume of our expanding universe = 2e33 x 8.467e47 = 16.934e80 m3
Atoms within our universe of 1.7e81 m3 at 0.1 atom/m3 = 1.7e80 atoms

1.7e80 atoms of mostly hydrogen and helium, even when compressed into
a black hole of 1e27 g/cm3 is going to be a whole lot bigger than a
bread box.

So, where exactly did this "size of an atom" notion or revelation come
from?

According to Einstein, something sure as hell existed, and/or
materialized out of less than thin air, so to speak (perhaps from
another universe).

Vaneck Size is relative. It was the spacetime of the first event of the
to be universe we see at this space time 22 billion years later, Lots
of great space between an electron and a proton. TreBert

So, exactly how big was the whatever seed of our universe?

As large as our Selene/moon?

As large as Eden/Earth?

As large as Jupiter?

As large as our sun?

The size of atoms has been measured directly--first by atomic resolution
electron microscopes and more recently by atomic force microscopes. no
theory needed and by the way the universe was not condensed to the size of
an atom prior to the big bang it started out even smaller.. theory begins I
believe at the plank length at zero plus plank time which is the time
necessary for light to travel the width of a hydrogen atom...about 1
angstrom... read " the whole shebang" I think it's titled by Alan Guth

Never trust anyone with the last name of Guth.

I have a much better theory. It has to do with other universes
tossing out their garbage.
