The universe has always existed.
man through history has been fascinating to observe the wonders of the universe in its various operations. Not surprisingly the great interest among humans to get to know what kind of Intelligent Designer behind such a wonderful building.
At all times man has tried to find explanations about how the universe emerged, why it is structured as we see with constant laws of operation. But while many find it difficult admit, the man is still very limited knowledge to understand its operation on any of its parts.
solar system as a standard of operation.
note that the Earth with the Moon and other planets are in motion, in addition to pivot move in orbits around a central point of the solar system. In the orbit closest to the star center situaos solar, and the following external orbits the Sun moving the other planets. In turn, the solar system moves with other stars in orbit around our galaxy, etc ...
Appreciating the dimensions of the universe.
already spend the time that it was not known if our galaxy was the edge of the universe. Today visitors can see how the universe is organized in structures, which eventually form part of galaxies and star systems like our solar system.
Astronomers realized that we live in a galaxy that is observed with spiral movement, in which the solar system is located in one arm of the spiral. Our Galaxy appears to be part of a local cluster that includes the Magellanic Clouds, the Andromeda Galaxy and 3 small satellite galaxies, near the same, plus some other small galaxies, for an approximate total of 19 sets. Our galaxy is part of a group of galaxies that form a cluster with other clusters that form what is called a supercluster.
The dimensions of the universe are exaggerating.
Humans have the tendency to feel superior to everything around us, so once we realize that something beyond us in size and intelligence, then we tend to do so sublime.
scattering attenuation.
Actually we are inside our galaxy, surrounded by different star systems that reflect large amounts of energetic radiation (electromagnetic waves), and everything we observe in the distance is through the holes that leave the galactic systems.
Since everything we perceive in the distance is through the spread of different kinds of electromagnetic waves when we observe the universe across vast distances, we are limited due to the attenuation of the waves . If we stick to the known laws to study how the waves propagate, we must apply the process of scattering attenuation. The results we have tells us that we can only observe the signals coming from lower distance to multiply the radius of our galaxy for a hundred times. Re distance still further reduced taking into account other factors of wave attenuation, such as radiation energy of the stars and the so-called stardust.
| our Milky Way galaxy | |
|---|---|
| diameter of the galaxy | 90,000 light-years |
| central Boom length | 25,000 light-years |
| Distance from the Sun to | center26,000 light-years |
| Thickness of the Galaxy at the Sun | 2,000-light years |
| Rotation Period of the Sun around the Galaxia_ | light 225 million years |
means that the parallax method is applicable to the Magellanic Clouds (LMC), estimated at a distance of 160,000 light years from our Milky Way, comprising about 14,000 light-years. It is one of the galaxies forming the Local Group that surrounds the Milky Way. Because of its distance from us helps us get a rough idea of \u200b\u200bhow are the other more distant.
The orbit of the stars follow laws related.
The main ideas about the motion of bodies in the universe goes back to Galileo. Newton later continued investigating how the orbit of the stars in the universe was governed by a set of established laws that are related to each other, which could explain math smart. Among these were the laws governing gravity or gravity.
