The Origins of Super-massive Black Holes

The super mass black hole is a massive black hole whose mass is equivalent to a large amount of solar mass. When the usual "galactic nucleus black hole" has a mass range between 100,000 and 10 million solar mass, the black hole is called super mass black hole. (Cardiff University 2014). Since the solar mass is considered to be equal to the mass of the sun, this will make the super mass black hole very large compared to the sun. A huge black hole with a large mass makes its gravity infinitely infinite. In other words, stars that are many years away from light are driven by super-massive black holes.

According to the general idea, the black hole has three types - Super Large, Miniature, Black Hole. Black holes are classified according to size and quality. It is well known that there is a super mass black hole at the center of a galaxy including the galaxy and the Milky Way where we live. Some super mass black holes have a mass that is greater than the mass of the sun. The small black hole is very small. Their masses are sometimes as small as the diameter of the pins. The common type of black hole is the type produced by several dying stars. There is a black hole called star. When gravity enters and the launch pressure becomes unbalanced, black holes are generated because stars have run out of nuclear fuel.

From ordinary black holes of 30 to 40 sun masses, how can we not reach ultra-huge black holes with millions or even billions of sun masses? This is a little strange. These monsters began in the early stages of the history of the universe, and they must have taken the initiative in some way. From the viewpoint of a true black hole, this Hawking radiation is very weak and weak, so it may not be possible to directly detect on a general time scale without having a practical effect. However, we are in the cosmology about ten years apart from a wise time scale, we have plenty of time. Since there is nothing to grow the black hole, this Hawking radiation blocks very slowly even the biggest monster.

LIGO's black hole is twelve times the mass of the sun. However, astronomers believe that super mass black holes must also collide. That is how the universe forms the biggest quality black hole. However, the gravitational wave generated by the super mass black hole pair has a wavelength that is too large to be seen in LIGO. I returned to the radio telescope. Astronomers recognize that gravitational waves can affect the very fast rotating core of pulsar pulses. Pulsar is one of the most accurate watches in the universe. Pulsar can deliver radio waves because radio waves that emit radio waves arrive as expected. Using a pulsar pair that separates the light of many years in the Milky Way, radio astronomers can look for signs of gravitational waves that affect pulses.
