Are there really aliens in the universe?
Astronomers often find mysterious and bizarre point signals when they explore the universe.
These signals sometimes have a certain pattern.
Scientists can first rule out that these signals are signals of human interference, but they have not been able to come up with conclusive evidence to prove whether it is an alien sending a greeting to our earth.
Today we will list three mysterious extraterrestrial signals and analyze them specifically What makes scientists creepy?
This is using the Australian radio telescope once discovered a mysterious set of electrical signals.
The mystery lies in the fact that it is a narrow-band electromagnetic signal.
And this 2G signal is similar to the 2G mobile phone signal that we all used to use.
One of the most critical reasons why scientists suspect that it is an extraterrestrial signal is that it is 4It was launched from near Proxima Centauri, 22 light-years away.
Everyone knows that in the three-body problem**, near the centrifugal is also the place where the three-body civilization appeared.
So scientists once wondered, could it be that this was a greeting from the Trisolaran?
Proxima Centauri B happens to be in the habitable zone of this area.
At one point, there was a suspicion that this was most likely a fast radio burst.
But if we think about it carefully, we will find that if it is a fast radio burst, then it is impossible for it to be launched from the same direction for five consecutive hours.
So this speculation was quickly judged to be a false inference.
This signal is a mysterious electrical signal discovered by American astronomers in 1977, which comes from the direction of Sagittarius and is also a narrow-band signal.
It has been more than 40 years since scientists discovered it, and the mystery has still not been solved. The mystery of it lies in the fact that it is 1420MHz.
As we all know, at the international level, such bands are generally not used by individual countries.
But for aliens, it's a good choice.
Scientists have responded to this signal by using line waves emitted by hydrogen, but so far they have not received any answers from this region.
Maybe it's just another cosmic phenomenon that we don't know about.
This signal is a mysterious electrical signal from about 3 billion light-years away from Earth.
Scientists have discovered fifty-nine pulsars in this mysterious region.
In more than 40 recent observations, they also received 1,652 heavy ** mysterious electromagnetic wave signals.
Since the discovery of these mysterious electrical signals in 2012, scientists have been able to find regularity in every observation until now.
But until now there has been no way to completely solve its mystery.
Some scientists believe that this is most likely a black hole and neutron star interaction.
So it's a new pulsar that stimulates the Earth.
But this claim was quickly disproved. Because this signal is emitted from about 3 billion light-years away from Earth, if it were the interference of a single pulsar, it simply would not have lasted so long and was so intense.
So there are also scientists who speculate.
It's very likely that a supermassive black hole is playing tricks behind it.
All mysteries are left to future science to explore, and I believe that with the continuous progress of human science and technology, our understanding of the universe will deepen step by step.
