The earth has received cosmic signals 13 times in a row, 1.5 billion light-years away from the earth. Are aliens saying hello?

The development of science can lead us to solve all kinds of problems. Although human beings have become highly intelligent creatures on the earth, we still haven’t gained much in the process of searching for extraterrestrial life. Over the years, we have tried to send detectors and signals to the universe and receive information from the universe. Many scientists think that alien life may be real, because in so many years, the scientific community has received mysterious signals from the universe.

A year ago, scientists in Canada received a mysterious signal, which appeared 13 times in two consecutive months. When scientists studied the signal, they found that the wave actually came from a place 1.5 billion light years away. At that time, they speculated that the wave was probably an alien greeting to human beings. However, the duration of this wave is too short, and scientists have not yet deciphered the content of this wave. This is a signal. In fact, it is what we often call a fast radio storm. Although the time is only a few milliseconds, the energy released can not be underestimated.

According to the data of scientists, fast radio bursts were discovered by human beings in 2007. Up to now, scientists have captured more than 60 kinds of fast radio bursts. Most of these fast radio bursts are of a single type. However, the radio wave signals discovered by Canadian scientists have been repeated for six times. Scientists believe that if they are naturally generated signals, they will not appear more than twice in a row, so it’s very difficult to understand It’s very likely that this signal was created by external forces.

How is the signal generated?

Of course, some scientists believe that if a neutron star rotates at a very fast speed, the intensity of radiation will also increase greatly. A neutron star in a high-speed rotating state may also release a fast radio storm. If two neutron stars collide, it will trigger a big explosion, and the brightness produced can be equal to tens of thousands of suns. Therefore, scientists are very interested With a telescope, we can observe the situation 1.5 billion light-years away, and even catch fast radio bursts.

Some scientists speculate that a neutron star can collapse into a black hole. This is because the gravity of a neutron star is very strong. If there are other celestial bodies and stars around it, it will soon be sucked away. When its mass reaches a certain level, it will form a black hole, generate a lot of radiation, and even send out wireless signals.

In fact, these are three reasonable guesses given by scientists. Because the time of rapid radio bursts is too short, human beings have no way to decipher the signals. So up to now, does extraterrestrial life exist? How are rapid radio bursts produced? It’s still an unknown number. I don’t know what you think of it?
