Hundreds of years ago, with the help of technology, mankind finally realized the dream of flying out of the earth. When we stand outside the earth and see the vast universe, we all feel the smallness of the earth and human beings.
Before human beings walked out of the earth, they always dreamed about the world outside the earth, which should be a very lively and wonderful space. But the outer space we really see is not as beautiful and wonderful as we imagined, with ultra-low temperature, ultra-super cosmic radiation, and a dark atmosphere. The whole universe feels so cold and cruel to us.
It turns out that the lively scenes we imagined have not been seen in the universe, and until now we have not discovered any extraterrestrial life and extraterrestrial civilization. Is human beings the only intelligent life in the universe? From the perspective of the vast universe, this possibility is very small. Most scientists believe that: alien life and alien civilization exist, but they may be very far away from us, and we have no power to detect them.
If the alien civilization is very far away from the earth, then human beings will not be able to go to the field to detect it before realizing the super-light-speed flight technology. Does that mean that before this, we have no hope of contacting alien civilization? of course not.
Although we could not explore and find alien civilizations before the super-luminal technology, there is a high probability that there will be intelligent civilizations that are much stronger than human beings in the vast universe. These intelligent civilizations may also be trying to communicate with other civilizations in the universe, and the method of contact may be radio waves.
The transmission speed of radio is very fast, and the wireless transmission we currently use can reach the speed of light. And this speed is not the limit of interstellar communication. If a civilization masters quantum entanglement technology and develops quantum communication, then it is possible to achieve super-luminous wireless communication.
As long as we can receive signals of this kind of extraterrestrial civilization that may exist in the universe, we can communicate without encountering each other. At least it will let us know clearly that there is an extraterrestrial civilization. We can even locate the galaxy where the alien civilization is located through the signal.
The vast universe is filled with countless radio waves, most of which are emitted by various celestial bodies. For example, planets, Hengde and nebulae produce radio radiation, and special neutron stars like pulsars can emit strong and regular patterns. Wireless signal.
In addition to the above wireless signals from celestial bodies, there is also a kind of extremely strong radio waves in the universe. The energy released in just a few milliseconds is equivalent to the sum of all the energy released during the life cycle of a star. This phenomenon is called in radio astronomy. Rapid radio bursts (FRB).
A fast radio burst is the strongest kind of wireless signal wave in the universe known to mankind. Its wireless wave can even transmit a distance of more than tens of billions of light years. It can be seen how powerful and terrifying its initial burst energy is. Scientists have been trying to solve the mystery of fast radio bursts, trying to figure out what is its origin?
Some scientists believe that FRB may be emitted by neutron stars or violent black holes, and scientists boldly speculate that these super-strong radio waves may come from advanced civilizations in the depths of the universe, and they are sending signals outward, hoping to rely on this method. Get in touch with other intelligent civilizations.
If the radio waves are emitted by an advanced alien civilization, then this kind of radio waves will inevitably be very regular. Although regular radio waves are not necessarily emitted by alien civilizations (such as pulsars), as long as they are signals emitted by alien civilizations, they must be regular.
Since 2007, astronomers have found more than 100 fast radio bursts in various directions in space. After research, they found that only 10 of them were recurring signals, and none of the FRBs showed regularity. But this situation has changed because of a new FRB.
A new detection study shows that 500 million light-years away, a spiral galaxy is regularly sending out radio signals of fast radio bursts. The study found that the FRB will release one to two radio pulses every hour, lasting about 4 days, and then restart after 12 days of silence.
This kind of regular FRB, from the perspective of the earth, sounds like the distant deep space is constantly sending us “call signals”. Through the tracking of this signal, we found its origin, which is a dwarf galaxy 500 million light-years away from the earth. So is this signal from celestial bodies or from alien civilization?
For this, scientists are still exploring and researching, and more researchers speculate that its origin may be that stars or black holes generated super-strong electric waves due to some circumstances, and then spread around the universe. Some people think that this may be caused by pulsars, because currently known celestial bodies, only pulsars can send out very regular radio wave signals.
Of course, these are just some guesses of scientists. What is the origin of fast radio bursts? More observational studies are needed. Only when more FRB signals are discovered can we have more data for analysis and find the real mystery behind it.
For many ordinary viewers, it is natural to hope that the rapid electric storms are emitted by alien civilizations, because this may be the best way for humans to hopefully communicate with alien civilizations. But if in the near future, scientists finally determine that FRB is indeed a super-strong radio wave launched into the universe by an advanced civilization in a distant starry sky, can we reply to such a signal?
Perhaps in the eyes of many people, we finally know that fast radio bursts are caused by advanced civilizations. What a rare opportunity this is to connect with alien civilizations. We should actively respond to the signal and wait for the visit or reply of the alien civilization. Is the fact really as good as we imagined?
I believe that many of my friends have heard of the law of the dark forest. Some scientists have suggested that the universe also has the law of the dark forest. It may be very common for powerful civilizations to bully and destroy low-level civilizations. Hawking has also issued warnings many times: to remind humans not to try to contact alien civilizations.
From the perspective of intelligent life, we must understand that not all alien civilizations are friendly. There are still various contradictions within human beings, leading to disputes of all sizes, and different intellectual civilizations may be even more cruel. In the eyes of advanced civilizations, humans may be tiny ants and will not take us seriously.
Once humans respond to the signals sent by advanced civilizations, then advanced civilizations will know that there are humans in the solar system of the galaxy. Then we send a spacecraft to visit the earth. It is difficult for us to figure out whether this visit is friendly or malicious.
If it is friendly, humans may benefit from this, allowing human technology to achieve a leap forward and become an interstellar civilization earlier. But if it is malicious, then what awaits the earth and mankind may be destruction, and human civilization will come to an end and disappear into the universe.
The editor once read a science fiction novel. The advanced civilization of the universe in the novel is to find other intelligent civilizations by sending radio waves in all directions of the universe and casting a net. If a wise civilization responds to such a signal, the high-level civilization will destroy the wise civilization. The purpose is actually very simple, that is, it does not want other low-level civilizations to develop into high-level civilizations, thereby threatening their cosmic supremacy.
This shows that mankind should be more vigilant about alien civilizations, and we should not respond to the searched signals of suspected alien civilizations. It is human beings who continue to develop science and technology. When will we truly become stronger and become an advanced civilization, and then go to the depths of the universe to explore and interact with other civilizations. Weak countries without diplomacy are also adapted to the cosmic civilizations. Low-level civilizations have no right to choose in front of high-level civilizations.
