If we can create a time machine so that the accelerator could see the future, we will all witness the colossal events that occurred in front of our eyes. Milky Way galaxy, where the sun and the planet we are, will collide with the Andromeda galaxy, the Milky Way galaxy closest neighbors.
Milky Way Andromeda flying at speeds approaching 300 000 miles per hour, 100 times faster than a bullet shot at high speed. When colliding, Andromeda Milky Way galaxy will change us forever.
Millions of stars will be ejected from its orbit. Space dust and gas clouds will collide in between. Because so hard collisions, born millions of new stars. Processes that occur over hundreds of millions of years it will tear the structure of these two giant galaxies.
It was concluded by astronomers at the National Institute of Aeronautics and Space United States, NASA, after years of observing space objects that bring them to the theory of birth and death of a galaxy.
Milky Way and Andromeda
Milky Way is a galaxy that is home to our sun and planet-planet or what is often called the solar system. The galaxy has a diameter of 100 thousand light years. A light-year is a measure of distance equal to the distance traveled by light moving at 300 thousand miles per hour in one year. If the whole mass of existing stars in the Milky Way are added, the mass of the Milky Way itself will be equal to 750 billions, a trillion times the mass of the sun.
By using radio waves, astronomical investigations on the distribution of hydrogen clouds in space reveal information that the Milky Way galaxy is a spiral-shaped. Therefore, its mass is mostly in the whirlpool galaxy itself. For convenience, the shape of this galaxy can be imagined like a bowsprit cakes sold in traditional markets in Indonesia.
Meanwhile, the Andromeda galaxy is the largest galaxies nearest the Milky Way galaxy. Andromeda's first recorded as a "little cloud" by the Persian astronomer Abd-al-called Rahman al-Sufi in about the year 905. Then, nationality Bavarian astronomer, Simon Marius, finding this galaxy and record the findings in 1612. Without knowing the discovery of al-Sufi, and Marius, and then confirmed by the presence of Andromeda bebepapa world's astronomers in the following years.
Andromeda galaxy is classified as a giant galaxy because it has a diameter of about 200 thousand light years, or two times bigger than the Milky Way galaxy. Andromeda has a mass of 300 to 400 billion times the mass of the sun. Typical round shape and large size makes it easy to galaxies observed even in moderate condition and the sky using a simple telescope.
Galaxy Evolution
Using the Hubble telescope located at an altitude of 612 km from the earth's surface and 28 000 km per hour speed around the Earth, NASA astronomers watched at any time, based constellations constellations were formed.
Because it takes light from a light source which is the object space through the Hubble telescope arrived in the mirror, every photo shoot that made the Hubble images record the actual events of the past, not current events.
At the beginning of the formation of the universe, galaxies collided with another galaxy ten times more frequently than the collision of galaxies in the present. This conclusion was made based on astronomical observations as follows.
Collection of stars that formed 12.6 billion years ago show the young stars who gathered at certain locations in space. Observations on a collection of stars at the age of the universe that is younger, which is about 9 billion years ago, shows the galaxies which "bubbles" without regular shape.
Finally, the observation of the universe that is relatively older, or about 5.3 billion years ago, showed groups of stars with a far more obvious forms such as spiral plate when they collide with each other.
Sometimes galaxies collide in groups of two or three galaxies. This collides group will merge into one large galaxy. The discovery was later incorporated into a simulation that provides a surprising conclusion: galaxies form through the collision process. Antargalaksi collision process that continues until today.
Two galaxies collide
What menyebkan two galaxies collide? The simple answer to this question the force of gravity. As formulated by Isaac Newton, physicist who was born on January 4, 1643 in Lincolnshire, London, England, every celestial body will experience a tensile force draw with another celestial body.
This law is known as Newton's law of gravity. The amount of gravitational force between two celestial bodies will be directly proportional to both mass and inversely proportional to the square of the distance of the two bodies. However, when compared with the three other known natural forces in the universe such as the electromagnetic force, weak and strong nuclear force, gravity is the force of the weakest among the four styles.
If two galaxies are close enough from each other, gravity will pull them closer to each other. Like the Milky Way galaxy and Andromeda galaxy, the gravitational force both will bring these two galaxies are approaching.
When collide, the sun and our solar system do not collide with another star, but will "sail" without being influenced by the situations around through the galaxy that is changing shape.
If the sun is proportional to the size of a grain of sand on the beach attached to the soles of our feet, we had to walk about two miles before the next meeting of sand grains, ie the star Alpha Centauri.
When two galaxies collide, the stars will be passed. We can imagine this process with the condition of the car on the highway. If a moving car approaching corners, these cars will run one after another without having collided with another car.
Milky Way Andromeda flying at speeds approaching 300 000 miles per hour, 100 times faster than a bullet shot at high speed. When colliding, Andromeda Milky Way galaxy will change us forever.
