Cosmology | Earth, Solar System and Universe.

Always, the human being has been interested in knowing and understanding the universe and the laws that govern it. From different points of view, philosophy, Religion and science have tried to answer these questions. The part of the science that studies the universe in its entirety is called Cosmology.
Cosmology scientifically addresses issues such as the composition of the universe, its structure, shape, origin, evolution and final destination. To do this, served the astronomical observation and scientific knowledge. Other sciences such as astronomy, physics, and mathematics are useful for cosmology. Technological advances are critical in the development of modern cosmology.

Modern Cosmology

Modern Cosmology begins around the year 1700. Then there is the idea that all the stars of the milky way formed a group in the midst of a universe much greater. Earlier, it was believed that our Galaxy was the entire universe.
In century XX Cosmology is marked by two major advances: Einstein's theory of relativity , and the inflationary theory. Relativity unifies the space, time and gravity, and change the vision of the fabric of the universe. The inflationary theory poses that space has expanded quickly after the Big Bang.
Today, the study of Cosmology is focused on particle physics. The main instrument of current Cosmology are not telescopes, but large particle accelerators. Looking for particles that help solve mysteries such as the composition of dark matter, what happened in the first moments of the universe, or if there are other dimensions that we don't see.
