With all those spikes it's no surprise most people sneeze... :P
The microscopic world is about as fascinating as the biggest universe
structures and I wonder if in fact they are not the same. As in, once
we devise a sufficiently accurate device for seeing further we realize
our universe is just a grain of dust and inside a grain of dust lies a
whole universe...

Man, that is so deep... o_O
But hey, you aren't the first person to point out that the solar system
looks conspicuously like the internal structure of an atom. ;-)

All coated in a thin layer of gold...

...like this:

Actually, apparently you can design a SEM that works without the gold
coating, but the resolution is lower. (And you still can't do it with
"wet" samples; they must be dried somehow first.)

Maybe with the misconcepted view of the structure of an atom 100 years ago.
An atom is *not* a bunch of spheres forming a core with a bunch of smaller
spheres orbiting around.

Idyllic, but not very scientifical.
You cannot "see" an individual atom because the wavelength of visible
light is too large. It's also a misconception (cleared about 100 years
ago) that subatomic particles are spherical (or have any definite shape
for that matter).

SEM can even be used to take pictures of your closest friends

Kind of the other way around, actually.
The first models of atoms were big blobs of pudding with raisins in it.

No it doesn't. Planets aren't waveforms that appear to occupy the entire
volume of space in a certain pattern around the central element and turn
into particle-like entities under certain conditions; they're *always*
particle-like entities, with well-defined position and velocity that can
both be measured. (Mind, it helps that what we're measuring them with is
unable to affect either attribute on the levels we use.)
