The mystery of black holes scattered in the sky is said to match the concept of a strange event that occurred in the Bermuda Triangle, if the ship or aircraft that crossed the area of water that disappeared suddenly.
However, the black hole is like a giant hole, its size larger than the sun and the sky in the sky sucking whatever it approaches including the planet. In fact, the force of the attraction causes the light that does not have the power nor is able to escape.
The mystery that envelops the black hole event is however only capable of being studied from afar because the capabilities of science and real human technology still have not been able to bring them up to the hole.
Using telescopes and observations of the stars that are aligned with the various physical laws that lie around the earth, various theories are put forward to fill the void in the room of answers that triggered the mystery of nature.
This theory is used by astronomers is the same theory used vacuum cleaner - power black hole occurs following gravitational pull in the hole is strong compared with the pull around. In fact, anything that comes to him will be sucked.
However, his gravitational power is 'extraordinary' and very powerful. It is said if the force of gravity is a form on earth, it will make the size of the planet to be as small as a ball that jejad about one centimeter.
Black hole theory actually put forward more 200 years ago. In 1783, Western scientist John Mitchell sparked a theory about the possibility of a black hole after he examined Isaac Newton's theory of gravity.
He argued that if the object being thrown perpendicular upward would be detached from the gravitational effect of the earth after reaching more than 11 kilometers per second, then surely there are planets or other stars that have greater gravity than the earth.
However, the word 'black hole' was first used by American physicist John Archibald Wheeler in 1968. Wheeler gave it a name because the black hole can not be seen, the light is drawn into it so that the surrounding area becomes dark.
According to the theory of stellar evolution, the origin of black holes is a kind of blue star that has a surface temperature exceeding 25,000 degrees Celsius. When the burning of hydrogen in a blue star that takes about 10 million years to complete, it becomes a giant blue star.
Then, the star became cold and swapped to the giant red star. In that phase, due to its own gravitational pull, a gigantic red star experiences a powerful explosion called Supernova and produces two star types namely the star Netron and the black hole.
Observations from space X-ray telescopes for more than a decade, showing the force of the gravitational pull of the hole causing a star to be destroyed and swallowed by it.
Before this, astronomers have seen how black holes suck the gas flying around it. The aspirated gas gets hot and radiates in various wavelengths, ranging from radio waves to visible light waves and X-rays.
Based on observations, astronomers from the Max Planck Institute for Extraterrestrial Physics, Germany, once saw a star approaching a gigantic black hole was finally lost in the hole.
The giant black hole seen is at the center of the RX J1242-11 galaxy, which is 700m light-years away from Earth. The black hole-infested star also has the size of the sun of our solar system.
The star was crushed bit by bit and sucked into the hole for several days. In the first rank, the star loses gas around it.
After that, the star became hot until millions of Darajat Celsius and lost by the black hole. In the process, it releases a strong force that is equivalent to the energy generated on the Supernova explosion.
Astronomers impress the position of black holes by observing light around stars or gas in space. If there is no light in the place but in the vicinity there are many aerial objects going to a point at high speed before it disappears, then the point is denoted as a black hole.
There are many black holes throughout the universe even there is a theory that says in the Milky Way galaxy there is also a black hole. Precisely the same problem arises, whether the sun and the planets that surround it including the earth will be blackened the black hole it?
Astronomers give the answer, 'no' because compared to other galaxies, the black hole in the Milky Way is said to be in a state of calm due to the few objects around which he sucked.
The mystery that envelops the black hole will continue to attract astronomers so that one correct answer is obtained. While humans have not been able to venture deep into space, jawapbn fails to come and various theories without evidence will continue to be put forward to 'solve' the mystery of nature.
Fact: Black Holes
Known as 'black star' and 'singularity'.
Discovered in 1783 by John Mitchell.
The extent exceeds the size of the sun.
Suck everything around it including stars and light.
The theory of straws due to gravitational pull in the black hole is stronger than the surrounding area.
The theory suggests it was the result of the supernova eruption of a giant red star.
