Hushed but not silent,
destined for collision,
even clashing with itself,
Gravity is not a force
like other forces,
but a consequence
of space-time, not being flat--
a curved surface, warped
by the distribution of mass,
energy in the objects,
following the nearest
straight path.
Upon a geometric surface,
where geodesics exist--
like our equator,
a circle, 'round
the center of Earth.
These are invisible
curved lines
between two points,
pilots capitalize on.
Shortening routes by
flying parallel
with the Earth's
spherical design.
Jumping from 2
to 4 dimensions--
it is not gravitational attraction,
rather, a distortion in space
around objects.
Like the sun and the Earth,
caught in a curvature
created by these heavenly masses.
Two bodies, intertwined in a dance,
Both calling and answering.
Improvising the choreography
when one falls out of step.
Even light adheres to it,
bending around each object,
it's deflected.
Slipping around corners,
and escaping tight places.
Causing stars to appear
in positions
different than where we
predicted.
Time runs slower,
or faster, here too.
Depending on our proximity
to a massive object.
A principle of equivalence--
Freely moving, or
under gravity's influence?
The laws of science match.
Though more technically
in overlapping patches.
The cosmos, wrapped
in a quilted romance.
It's impossible to say
what's truly at rest, or
uniformly accelerating,
in an empty space--
Are you floating or falling?
There is no difference
between them,
inertial and gravitational masses.
A relentless and logical reasoning
historically unmatched.
But how does that relate
to the clicks of a clock, when
they remain the same?
Well, relatively, they do not.
Uniform acceleration still
plays its part.
Even though light has no mass,
and its speed is constant,
traveling between two curved points,
the time it takes may be delayed,
Or sped up,
ever more drastic
as it relates to the observer's positions
and gravitational interactions.
Thus, we developed a map,
with four quadrants,
for its practical importance.
Increasing the accuracy
of our navigational systems
using signals from satellites,
that would otherwise
leave us miles off
from our desired locations.
It even impacts our circadian rhythms,
and we play around with the implications.
The more gravity exerted on our body,
the longer we stay young and hot!
Lightspeed baby!
To infinity and beyond!
Conversely,
we grow ever more certain:
our universe has a conclusion.
Time and space, having
a dynamic structure
affected by the masses
and forces in motion,
influencing and influenced--
have reshaped our ideas
of an infinite universe.
It is now hypothesized
as finite, expanding
from a single point,
toward a finish line,
unribboned, cold and fridged,
or collapsing in on itself,
only to begin again.
With a big bang, and
it's life, off to the races,
once more.
