10 Great Mysteries of the Universe

The world is full of mystery. The important thing we always remember to God.  
Here are 10 great mystery of the world:

1.Antimatter   

 As the evil Superman, Bizarro, the particle (normal matter) also have opposite versions of themselves called antimatter. For example, an electron has a negative charge, but the antimatter positrons have a positive charge. Matter and antimatter annihilate each other when they collide and their mass is converted into energy via Einstein's equation E = mc2. Some futuristic spacecraft designs incorporate antimatter engine


2.Cosmic Background Radiation

 This radiation is also called the Cosmic Microwave Background (CMB) which is the remnant radiation that occurs when the Big Bang birth of the universe. First detected in the decade of 1960 as a radio noise that appear scattered throughout the universe. CBM is considered as the most important evidence of the truth of the Big Bang theory. Accurate measurements by the WMAP project showed that the CMB temperature is -455 degrees Fahrenheit (-270 Celsius).


3.Extrasolar planets (Exoplanet).

Until the early 1990s, we only know our own planet in the solar system. However, today astronomers have identified more than 200 extrasolar planets outside our solar system. Search the Earth both seem to have succeeded until now. Astronomers generally believe that better technology is needed to find some of the world as on earth.




4.Neutrino

Neutrinos are elementary particles are massless and uncharged metal that can penetrate the surface. Some of the neutrino is penetrating your body while reading this article. Particles "phantom" was produced in the nucleus of stars and supernova explosions. The detector is placed beneath the surface of the earth, below sea level, or into a large chunk of ice as part of IceCube, a special project to detect the presence of neutrinos.

5.Mini Black Hole

 If the theory of gravity "braneworld" radically new and proven correct, then scattered thousands of mini black holes in our solar system, each about the size of the atomic nucleus. Unlike black holes in general, these mini black holes are the remnants of the Big Bang and affect space and time in different ways. 




6.Vacuum energy.

 Quantum physics tells us that contrary to appearances, empty space is a bubble made ​​of subatomic particles "virtual" who are constantly being created and destroyed. The particles that occupy each cubic centimeter of space with a certain energy, based on the theory of general relativity, produces antigravity force that makes more space to expand. Until now no one really knows the cause of the universe's expansion. 


7.Gravity Waves

Gravitational waves are distortions fabric of space-time predicted by Albert Einstein's theory of general relativity. The wave propagates in the speed of light, but weak enough so that scientists hope to detect them only through a colossal cosmic events, such as the merging of two black holes as in the picture above. LIGO and LISA are two detectors designed to observe these elusive waves.





8.Dark Matter 

Scientists think that dark matter (dark matter) is the largest constituent of the universe, but can not be seen and detected directly by current technology. Candidates range from heavy neotrino to invisible black holes. If dark matter really exists, we still must require better knowledge about gravity.






9.Quasar 

Quasar glistened at the edge of the universe that we can see. Quasars release energy equivalent to the energy of hundreds of galaxies combined. It could be that quasars are a very large black hole in the hearts of distant galaxies. This image is the quasar 3C 273, which was photographed in 1979.








10.Collision Between Galaxies.

Apparently each other galaxies can "eat" each other. Even more surprising is the Andromeda galaxy is moving closer to our Milky Way galaxy. The picture above is a simulation of Andromeda and our galaxy collisions, which will occur in about 3 billion years.





Hopefully this article add your insight!
