Considering all the amazing,
remarkable, incredible, and
fantastic (if not necessarily
wise...) scientific and
engineering feats that We
Humans have managed to
pull-off during the last
10,000 years or so,
We have (...understandably)
an age-old, and therefore
*heavily* ingrained tendency
for 'bragadoccio', to "toot
our own horn", and a *lot*,
as We all rush about the
minimal land surface of this
water-ball, which Humans
(ironically) call
Planet 'Earth'.
[...see that little blue dot
to the lower-left of the Sun?
That's us. Not even as big
as an average sun-spot.]
Perhaps We All would have
a better grasp on just how
small and fragile Our own
little corner of Existence
is, were We All able to
appreciate the sizes of
things, and the spaces
between them, that are
all around Us
...*off* the planet!
For instance...
...when you look up at the
Sun in the sky?
That's not where it *really*
is at that very moment!
At a distance of 93 million
miles, it's SO far way that
photons, which travel at the
speed 'c' (over 186,000 mi
*per second*), will take over
eight *minutes* to get here.
That means that the 'Sun'
you see in the sky is almost
a 'ghost' of the Sun, because
at that moment, it's actually
*four* of its own diameters
further along the path to
what we call 'sunset'.
...but that's nothing!
The following 3 examples
are in order of 'bigness'.
They are of SUCH an order
of magnitude that thinking
about them too long might
just semi-jellify both of
one's pre-frontal lobes!
So... we have attempted
to re-format the scales
that are involved, by
using verbal images
called "theoretical".
*You* will be your own OHP,
because your imagination
can build a *much* better
image than any cgi-magic
we could present to you.
Think of this as
"literary radio".
You hear, or read,
and then your
imagination paints
the picture.
