Love at Arm's Length.

Imagine a desert stretching from Los Angeles to
New York City, from Seattle to Miami, a desert
covering the lower 48 states of the United States.
That is about the size of the Sahara Desert in
current North Africa. The sand dunes that cover
nearly a fourth of this desert are all that remains
of an ancient ocean, populated with prehistoric
crocodiles and the earliest marine whales.
There are no fossil records of these animal remains
to be discovered among these dunes. A million years
of bone abraded by sand would leave nothing for
scientists to research. Dunes are the sea now, its
waves driven by the wind.
D U N E
A decent dune can travel anywhere from one to over
one hundred and fifty feet a year. It all has to do with
wind, weather and what kind of shape your dune is in.
You don't want to bet on a star-shaped dune to win a
race because conflicting forces forms the sand into a
mountain going nowhere.
Your fastest dune is the Barchan Dune. The secret
lies in its sleek, aerodynamic crescent shape that
rushes the sand over the dune's crest in short order.
With any luck at all you should see it cross the finish
line in about ten thousand years.

Imagine your desert picnic being disrupted by shrimp
swarming the hot dog relish. Ancestors of the Tadpole
Shrimp, shown above, were undoubtedly marine dwellers.
Time played them false and their world eventually dried up.
Weather patterns shift with the millennia. The rains go
north. Oceans become isolated and die, its many
life forms now extinct. Evidence of their very
existence mostly lost.
Every once in a great while a freak genetic path
reveals itself, and we discover mermaids can
live out of water. This shrimp species spends
most of its existence in suspended animation.
Pooling rainwater revives this animal long enough
to propagate another generation before
returning to the rapidly drying mud and slumber.

These merchants transport bundles of salt
across 400 kilometers of the harsh Tenere desert
of Niger. Here temperatures are often above
one hundred and water barely exists.
The land is unable to support plant life.
If you know what you're doing
you can make enough money hauling salt
to support you and your camels.
Benefits include stars at night,
no traffic and few regulations.
No doctors. No retirement.
You are dirt poor.
Somehow, however, you own a smart phone.
And you have your dignity.

Parched desert lands bloom with agriculture once water
is reliably supplied to farmers. The soil's rich nutrients
are made available to cash crop vegetables such as
lettuce, Brussel Sprouts and asparagus. And the
growing season is year round. What could go wrong?
Salt.
Water evaporates in the desert sun, leaving
behind trace amounts of salt that accumulates
with each watering. In time, the fields harvest
only cheap hay because the land has become
too salty for growing finicky vegetables.
This isn't smart farming and irrigation methods
have become less wasteful, especially with the
rising costs of water.

Columbus stepping into the unknown.
Pilgrims landing on Plymouth Rock.
At least they could breath the air,
drink from streams and hunt for food.
The first humans to step onto Martian soil
are confronted with having to survive
a lethal landscape.
Of course, you must first survive the travel
to Mars which will take six to nine months.
You should set aside three years
if you plan to make this venture a round trip.
The greatest effort has been made to ensure
your comfort and safety. Nonetheless,
keep in mind you are pioneers, the pathfinders
of civilization. There are no lifeboats, no parachutes,
no spare-parts and no do-overs available
on this voyage.
Thoughts and prayers.

The beginning of everything was about 14 billion years
ago. Creation. The Big Bang. From inside an infinitely
small speck of existence came forth all that we know
of the universe today. Conventional wisdom among
scientists fifty years ago was that the universe is infinite
and time has neither a beginning or an end.
That idea was thrown out once we discovered that
the galaxies and stars are not static. Our Milky Way,
along with the trillion other galaxies of the known
universe, is rapidly moving away from the theoretical
creation point of existence. Hmm. What was the
nature of existence prior to the Big Bang? Anything?
A previous universe, perhaps, that collapsed from
its own weight into nothing. Or was there a timeless
existence of null until there suddenly wasn't.
Mathematics won't solve this equation because
we don't know the variables. What is it we are
dealing with? Science or philosophy?

The universe had existed nearly ten billion years
before a galactic cloud of dust began to coalesce
into our sun and its entourage of planets, comets
and asteroids. The four planets closest to the
sun's gravitational pull - Mercury, Venus, Earth
and Mars - consist primarily of metals and the
heavier elements. The gas giant planets -
Jupiter, Saturn, Neptune and Uranus - consist
mainly of the lighter elements.
The dust cloud itself contains the particles of stars
that exploded once their nuclear reaction had run
its course. This is a process of renewal practiced
at the galactic scale. Stars are born from an accretion
of matter in a vacuum. A nuclear reaction occurs
giving the star a lifespan of energy. Depleted stars
may explode. The matter they release is now
available for new creations... stars, nebula,
galaxies, black holes, dark matter, and more waiting
to be discovered.

Early in the formation of our solar system, Theia,
a planet nearly the size of Mars, collided with the
still molten Earth. The enormous quantity of magma
thrown into space resulted in the formation of
Earth's moon - itself a planetary object almost
the size of Mercury. It also rotated twice as close
to the Earth as it now does. We would be startled
by the size of the moon in the sky when it passes
so near to where we stand. Luner Phobia would
skyrocket.
H A D E A N E R A - H E L L O N E A R T H
The first half billion years on Earth consisted of
oceans of molten rock bombarded with asteroids.
Eventually the planet cooled enough to have the
beginnings of a crust form on the surface.
Volcanos were then believed to be prevalent.
This was a time of extreme heat, toxic gases
and planetary turbulence. Nothing from this
time has survived this period of constant upheaval.
S T R O M A T O C I T E - F I R S T F O S S I L S
It took a billion years from Earth's creation before
the first evidence of life appeared. A lot had to happen
before there could be life. The crust the planet needed
to support life required the surface to cool. Eventually
the thick vapor atmosphere would condense into rain.
After a few million years of rainfall the Earth's surface
will be covered in oceans.
Here was nature's nursery for invention.
There is no way of knowing how many failed
molecular attempts at producing life occurred
before something clicked and the enterprise
of life was off and running. Sort of.
It took another half billion years before life
discovered the performance advantage
displayed by cells with a nucleus.
Random trial and error over a million generations
is the method of genetics, DNA, the molecular
code providing life.
C A M B R I A N E X P L O S I O N O F L I F E
For the next two billion years the Earth's oceans
remained a soup of mostly single cell organisms.
Then multicell life appeared about 560 million
years ago. Individual cells organize to create
something greater. The various cells of the organism
had different specialized tasks. They become
dependent on the whole. It was the more efficient
path for survival.
This development brings about an explosion
of life forms that radiate out through the
Cambrian Era. The types of organisms
became increasingly specialized, and became
a part of increasingly sophisticated habitats.
Most every animal type alive today can trace
their creation back to this Cambrian period.
