The sun and the earth and all the planets and moons and planets Dwarfs
Asteroids and comets and the solar system ... all short
Since formed about 4.6 billion years of nebulous cloud
Composed of swirling gas and dust Andjmt and united thanks
The tremendous force of gravity
However, this nebula nebular did not have a particular form in the beginning
How the solar system taken Bkwakbha and Oqmarhm
The form of a flat disk?
We all know the planetary model of the atom
It is certainly wrong for atoms
But it also suggests that the planets revolve around the sun may
In any direction was
Is our solar system unique Bastoaúha?
Or that the planetary model of the atom in the wrong way?
Inevitably our solar system is not unique
Many extrasolar planets belong to groups flat
Many of the galaxies have a flat shape
Equipped with disks of black holes Flat
Saturn's rings flat
Etc.
So, why the universe is preferred planar shapes
Despite the presence of three-dimensional space?
The answer is related to two things: collisions
The fact that the space in which we live three-dimensional
Ali patient. I will explain to you why
Within any set of interconnected objects by gravity, if the spin and move quickly
It is almost impossible to predict the course of the movement of each body separately
However, all of the objects as a group
Revolves around its center of gravity and a total value of one
It may be difficult to determine the direction of the rotation completely
But mathematics indicate the presence of a planar
This rotates the nebula as a group
In two-dimensional space, every cloud particles in a flat spin
Be flat by definition. It is present in two dimensions
But in three-dimensional space, although the nebula in a flat spin
Particles can move up and down from this level
When these particles collide, all movements up and down
Tend to cancel each other out. Energy lost in the collision and agglomeration
But the whole bloc inevitably continue to rotate
As the amount of rotation in any isolated system in the universe
Always remains constant
Over time, lose the nebula due to collisions and thick clusters
And turn into a two-dimensional almost revolving disk. Solar as a group or spiral galaxy
While, in four-dimensional space, math indicates the possibility of the existence of
Separate and complementary levels of turnover
It is difficult to imagine in our minds that think in three dimensions only
And it also means that the particle does not move up and down, and do not lose energy by collisions
Thus, cloud particles remain as they are ... cloud
If, only in three-dimensional space can cloud or galaxy
To start a non-planar, and become flat
It is definitely a good thing, because we need to those blocs in article
In order that the planets and stars are formed, and in order that we ourselves are shaped
Even for some of us who still believe that atoms have this shape is formed Subtitles End: mo.dbxdb.com
