Gravity

The definition as described by wikipedia:
is a natural phenomenon by which physical bodies attract with a force proportional to their mass. In everyday life, gravitation is most familiar as the agent that gives weight to objects with mass and causes them to fall to the ground when dropped. Gravitation causes dispersed matter to coalesce, thus accounting for the existence of the Earth, the Sun, and most of the macroscopic objects in the universe. Gravitation is responsible for keeping the Earth and the other planets in their orbits around the Sun; for keeping the Moon in its orbit around the Earth; for the formation of tides; for natural convection, by which fluid flow occurs under the influence of a density gradient and gravity; for heating the interiors of forming stars and planets to very high temperatures; and for various other phenomena observed on Earth.


Gravitation is one of the four fundamental interactions of nature, along with the strong force, electromagnetism and the weak force. Modern physics describes gravitation using the general theory of relativity, in which gravitation is a consequence of the curvature of spacetime which governs the motion of inertial objects. The simpler Newton's law of universal gravitation provides an accurate approximation for most calculations.


What would you do without gravity? The simple attraction  you have to a simple object carries a gravity. Without that attraction you would be left with almost nothing to look at or consider. Gravity will cause you to fall and it can cause you to get lifted. When you can display a high gravity toward a situation or person, that person or situation therefore tends to shift it's current direction toward your gravitational pull. It may be similar to why the stars in the sky 'twinkle'. Not only is the flickering caused my the atmosphere, it is also caused by gravity. Imagine a star 100 light years away, well there is probably 1,000,00 stars, planets, and other masses that the light from that star must pass by before it reaches your eye. Every mass the light passes..even nearby..will cause a slight pull on the light ray, making that light shift to the left or right by just micrometers..even if that. This pushing and pulling of the line light ray through space causes it to appear to twinkle.
Same goes with that situation, see your size is relative. Imagine all the millions upon billions of atoms and small space masses between your self and a situation or person. Is there a greater difference in the distance between situations and your self or another person and yourself? Maybe not by much. But all the either small or large gravities will effect the way a situation is handled. So be careful in the how much worry you put on a situation or be careful is how hard you may be on someone. Because a misunderstanding can come in any form and sometimes the people you love are very close and they will want to have a better understanding of how much you love them, or just simply want you to know they love you.
Gravity can be anything you want it to be. It is an extremely weak force in comparison to greater forces in the universe (strong, weak, electromagnitism).  
 

The Center of Gravity

The military Jeep was said
to have had a high center
of gravity, therefore
subject to tipping:
if you took a curve too fast
you might turn over.
A person with very short legs
has a low center of gravity
and will not tip over easily.
The ottoman likewise.
When a person is lying flat
he or she has the lowest center
of gravity possible, as does
a sheet of paper on a table.
People floating around
in outer space have little
or no center of gravity
because there's not enough gravity
to have a center.
Gravidanza is the Italian word
for pregnancy, which sounds
more serious than the English word
and may remind us of sentences such as
"The situation is very grave."
Every situation has gravity,
it's a question of how much.
People too have gravity—
of manner, of morals, and of body.
It is good to have gravity
but not too much of it:
like a bag of cement,
you might not be able to move
around or make ethical distinctions.
But with too little of it
you are flighty, your feet
hardly touch the ground.
Though cement and flightiness
have their charms,
it's better to find
your center of gravity
and have it be the place
you radiate out from.

Once I lay in bed ill, unable to move,
but in my head
I was flying and bouncing around.
But illness has no charm
and when it becomes very grave
your gravity edges toward
the most perfect center of gravity ever.
