When talking about the most terrifying celestial objects in the universe, the first answer that comes to our minds is black holes.

That's right, with its strong gravity, black holes can be said to be invincible in the universe.. For any object, a black hole is synonymous with "one-way journey" . Whether it is stars, light or dust, it will be swallowed by the black hole and never return.

With the development of astronomical observation technology, in recent years, scientists have discovered a celestial body that is more mysterious and terrifying than a black hole, which is the quasar .

Mysterious celestial bodies far beyond the Milky Way

• What are quasars?

Quasars are, simply speaking, objects similar to stars, but they are not stars and do not emit heat. The reason why a quasar is said to be similar to a star is because the radio waves it emits are very similar to stars.

In the universe, we can observe many radio sources similar to stars, but we cannot find the existence of optical objects, they are quasars.

Previously, in the perception of scientists and ordinary people, black holes were the most powerful objects in the universe. However, with the discovery and study of quasars, this perception will be overturned, and the black hole's position as the boss of the universe will not be guaranteed. .

This is because, after gradually gaining a deeper understanding of quasars, scientists discovered that they can actually kill black holes instantly.

Specifically, the horror of the type can be divided into three aspects, is brightness, speed and energy. The brightness of

• quasar. The surface brightness of

quasar is extremely high. Scientists once discovered , a quasar from 12.8 billion light-years away. Its brightness reached 430 trillion times the brightness of the sun.

No wonder, when scientists describe the brightness of quasars, they can't help but choose the word "extraordinary" to describe it.

More importantly, all quasars come from far away from the Milky Way. Their redshift and values ​​are very high. Therefore, all quasars are moving away from the earth at high speed. Some quasars are different from the earth. The distance even reaches 10 billion light years. If were not for its unusual brightness, humans might not be able to discover the existence of this kind of celestial body.

• The energy of quasars

In addition to their unusual brightness, the energy of quasars also exceeds our imagination.

The size of quasars is generally smaller than the size of galaxies, but the energy they release can reach hundreds of billions of times the energy of galaxies.

So, how huge is the energy of quasars?

To give an intuitive example, suppose there is a photovoltaic panel as big as the earth, and we place it about 100 million kilometers away from the quasar. Then the power conversion it receives within 1 second can be The level of human civilization directly breaks through from level 0.72 to level two.

• The speed of quasar

In our understanding, the speed of light represents the ultimate speed of movement. The movement speed of any object cannot exceed the speed of light. The great physicist Einstein also once said that the speed of light remains unchanged and cannot be exceeded.

However, the discovery of quasars has put "the speed of light cannot be exceeded" into an embarrassing situation, because on quasars, scientists have discovered many super-light phenomena that are dumbfounding.

The quasar "3C 273" located in Virgo is one of the closest quasars observed to the earth so far. Through the study of the emission spectrum of "3C 273" , scientists found that the difference between its two radiation sources The separation speed is very fast. The average separation speed of per hour reaches 2.88 million kilometers/second.

You must know that the speed of light is about 300,000 kilometers per second. It can be seen that the separation speed of this quasar has far exceeded the speed of light, which is 9.6 times the speed of light.

Who is the strongest celestial body in the universe?

Before the discovery of quasars, as the end of all things, black holes have always been regarded as the "strongest king" of the universe, and they have always been an existence that awes everyone.

However, after the discovery of quasars, the status of black holes as "the most powerful celestial body in the universe" began to be in jeopardy. Especially after knowing the terrifying speed, brightness and energy of quasars, I believe everyone will also wonder, between quasars and Who is the most powerful black hole?

Next, let’s take a look at which of the two is stronger and who is weaker.

Let’s first look at the energy comparison between quasars and black holes. The huge energy of the quasar comes from its core. In fact, the center of the quasar is a supermassive black hole.

is different from other black holes in that the black hole of quasar can not only swallow the surrounding cosmic matter, but also generate huge energy through friction, including light energy, thermal radiation energy, etc. The energy of

quasars will radiate into the universe in the form of visible light, X-rays and radio waves. With huge energy and ultra-high speed, the energy of this radiation can swallow the black hole instantly.

Let’s look at the speeds of the two. In this regard, the super-light quasar clearly wins. If the speed of a black hole is like a slow-moving turtle, then the speed of a quasar can reach the level of a rocket, and it is moving all the time.

In addition, wherever the quasar passes, all the matter in the universe becomes its food. Moreover, if it stops "eating", then quasars will still "starve" to death in the universe.

Therefore, scientists believe that at present, the most powerful celestial body in the universe should be quasars, and black holes, which are the end of all things, are just part of quasars.

The terrifying quasar

One quasar already has such a high degree of dominance, so how terrible will it be if quasars gather together?

During long-term research, scientists actually discovered a quasar cluster. Over the long history, these quasars have continuously devoured matter and expanded themselves. Up to now, the diameter of the quasar cluster has reached an astonishing 4 billion light-years.

What is the concept of 4 billion light years? Let's put it this way, we are all familiar with the Milky Way. According to scientists' estimates, there are 100-400 billion stars like the sun in the Milky Way alone. It seems that the Milky Way is already a quite vast galaxy.

However, the diameter of the Milky Way is only 100,000 light-years, how small is the Milky Way in front of the quasar group with a diameter of 4 billion light-years.

What's even more frightening is that quasars will continue to release airflows outwards. With ultra-high speed and temperature, these airflows are powerful enough to tear apart galaxies.

In addition, research has found that because the power of quasars is too powerful, its power radiates to many galaxies and stars in the universe, making them deeply affected by quasars. Even the spread of galaxies is hindered by quasars. .

Simply put, if quasars disappear, the number of stars in the universe may increase a lot, and the universe will become more dynamic.

Conclusion

"The morning bacteria do not know Hui Shuo, worms do not know Spring and Autumn". In front of the universe, the earth is still too small, and the power of human beings is even more insignificant.

Fortunately, quasars and extraterrestrial civilizations will not pose a threat to us for the time being. We have enough time to develop ourselves, continuously improve the level of technology and civilization, and be prepared to deal with cosmic crises.
