Why
Gravity?
May 1997--I watch my
son play and
am struck by how light he seems. It's as though
gravity has less of a tug on him than it
does on the rest of the world. Even on the
rare occasions when he falls, his 30-something
pound body seems to hit the ground
as lightly as a leaf.
We're at
Wainwright Park, located at the beginning of the causeway that
has homeless people living in the depths
of its dense hammock and the likes of
Madonna and Sylvester Stallone on neighboring
estates.
It's a
Wednesday afternoon
and the park is almost empty. Glen runs between
a playground and the sea wall, taking a
few trips down the sliding board then
throwing stones in Biscayne Bay. Back and
forth he goes, sliding and throwing,
sliding and throwing.
Since he's an
only child,
I try to be his big brother as well as father. I slide
down the board and collect rocks for him
to toss into the water, trying to keep up
as he runs around.
I remember
when I was
a kid, how much easier it was to run than walk. Walking was
too slow, and there always seemed to be
someplace I'd rather be than where I was
at the moment. One day, I consciously tried
to walk all the way to school, and
couldn't. About a 100 yards down the street,
I broke into a sprint, feeling free just
because I was moving fast. It didn't even
matter that running would simply
transport me to school sooner than later;
I ran simply because it felt so darn good.
Now, running
is a last
resort. Even as Glen charges hell-bent toward the sea
wall, I'm reluctant to switch gaits. But
I do, in part because I fear he'll stumble
and fall into the bay, and in part because
I fear trying to explain to his mother how
he stumbled and fell in the bay.
Splish-splash.
The only
things that end up in the bay are rocks, except for a
flat one that he flies around, making spaceship
noises. The rock does indeed
resemble the Millennium Falcon, the fastest
hunk of junk in the Star Wars galaxy.
Glen flies the spaceship rock round and
round, orbiting himself until he gets so dizzy
that he staggers. But he doesn't fall because
it's impossible to fall in outer space.
Back at the
playground,
I take a trip across the monkey bars. Swinging rung-to-rung, the
shoulder I separated playing
rugby years ago snaps, crackles and pops
like a bowl of Rice Krispies. One trip,
and I'm already breathing harder; my palms
feel ready to blister. I can't believe how
heavy I've become.
Actually, my
weight hasn't
changed much since college. But back then I could
do 20 pull-ups and jump high enough to grab
a basketball rim. Now, I don't even try
to do pull-ups because its easier and more
rewarding to just remember how many I
used to be able to do. And basketball rims
seem to have grown higher since my
college days, something I can only reach
with a ladder.
It strikes me
that gravity
must accumulate in our bodies over the years, that
each little cell absorbs a miniscule amount
of the force every moment we're on
earth. It pulls us down, down, down, until
we're, quite literally, in the ground.
Women who
jokingly explain
that sagging parts of their anatomy have
"succombed to gravity," are really quite
right. Gravity tugs, tugs, tugs at that once-firm flesh, never giving
it a break, until
it is broken down.
I suppose
this is all
Isaac Newton's fault, for he was the one who discovered
gravity. Of course, it was here all along,
but no one before him ever understood
exactly why things fell. He probably never
would have either if he hadn't been
conked on the head by an apple. Whereas
most people just would have said, "Ouch," and probably eaten the apple,
Newton asked
"Why?"
If he'd have
asked me,
I probably would have replied, "Things fall because they do. It doesn't
matter why, you just
have to adjust to it."
But Newton
was one of
those nerdy science guys who see the world in numbers and equations.
They think that energy
equals mass times the speed of light
squared whereas I think that energy equals
the amount of sleep you get divided by
the number of children you have. And whereas
I can cut a piece of pie in two
seconds flat, they can't cut a piece of
their pi without going to a zillion decimal
places.
But to each
his own.
If George Washington had been under that apple tree
and had a piece of fruit bop him on the
head, he probably would have chopped it
down and then made history by being the
only politician to twice accept
responsibility for his actions. Or, he might
have learned from his earlier experience
with the cherry tree that it's simply a
lot easier to lie.
If I'd been
under that
apple tree, I probably wouldn't have asked why things
fall, but rather pondered what it would
be like if things fell up:
If
things fell up instead of down,
It would be impossible to drown,
And just as hard to fill a cup,
And would you throw down instead
of up?
If things fell up instead of down,
Jack never would have broken his
crown.
Rain would fall from sea to
sky,
Would birds walk and elephants
fly?
If things fell up instead of down,
It would be easier to smile than
frown.
But I don't know if I'd want to
live there,
In a world that looks like Don
King's hair.
Of course, in
Newton's
time, Don King, like gravity, hadn't been discovered
yet (though I do believe that George Foreman
was around), so I would have had to
figure out another last line to my little
ditty. Fortunately, I live in a modern age
where it's common knowledge that gravity
is a cosmic force that has placed the
moon in the seventh house and Jupiter aligned
with Mars as the dawn of the Age of
Aquarius creeps over the horizon to bring
peace on earth for all mankind -- and even
some womankind.
Without
gravity, we'd
be lost in space, like my son Glen as he flies his rock replica of the
Millennium Falcon around
himself. Soon, he'll start asking me "Why?"
Why this and why that and just why, why,
why. I look forward to learning a lot, like
why the sky is blue, why bad news is inherently
more interesting than good news and
why real estate is so high in south Florida even though it will all be
underwater in a few decades. And with each answer
we discover, the gravity of knowledge will
accumulate until I learn that I can no longer
do even one pull-up, and Glen will learn
to worry about pimples and tests and a date
for the prom, a college major, a job
with health plan, rent, mortgage, a wife,
kids, car payments...
Uh-oh. It
looks as though
this column is spinning out of control again. So I'll
stop writing and just let it fall where
it may, in your hands, or maybe the bottom of
the bird cage tray.
