Is it a signal from an alien when astronomy receives a mysterious pulse opposition?

Many times stars can also produce pulsed signals

Personally, there are aliens.

Of course not, it may be because the pulse signal changes suddenly and instantaneously, and the voltage or current that acts for a very short time is called a pulse signal. It can be recurring or non-cyclic or single. A pulse signal is a discrete signal with a variety of shapes, and compared to ordinary analog signals (such as sine waves), the waveforms are discontinuous in the time axis (there is a clear separation between waveforms) but have a certain periodicity.

The most common pulse wave is a rectangular wave (i.e., a square wave). Pulse signals can be used to represent information, and can also be used as carriers, such as pulse code modulation (PCM), pulse width modulation (PWM) in pulse modulation, etc., and can also be used as clock signals for various digital circuits and high-performance chips. The so-called pulse signal is expressed in plane coordinates as a curve with countless breakpoints, that is to say, the limit of the point does not exist in some places periodically, such as sawtooth waves, and there are also signals from digital circuits used in computers, 0, 1.

Pulse signal, that is, a signal like pulse beating, relative to DC, intermittent signal, if described by water flow, DC is to keep the faucet on and dripping, and pulse is to keep turning on and off the faucet to form a water pulse. You turn on the flashlight and the light is on, this is DC, you keep switching the light on and off, it forms a pulse, and the speed of the switch is the frequency of the pulse.

Not necessarily, but it is possible.

Are there any aliens? According to the Fermi paradox proposed by the famous Nobel laureate Fermi, if there are aliens, then they may have come to Earth and exist somewhere, but they just didn't communicate with us, maybe our technology is too backward to detect them; Or that there is no other civilization in the universe.

Say the Earth, the Solar System, the Milky Way, what Orion, Ursa Major, this and that, Libra, Aquarius, how vast are these ranges, so vast that you have fresh water on Earth, you have life on Earth, people don't have it, it's unlikely.

There have always been reveries about aliens in ancient and modern times, but now human beings have not been able to actually detect the existence of aliens, although many people have always claimed to have witnessed aliens visiting the earth and even having contact with themselves.

Personally, I think there must be, maybe I'm reading your post.

I am, but you can't find me.

Humans just need to wait quietly to develop their own technology so that one day they can communicate with them.

I think humans can study this kind of signal, but there are radio signals everywhere in the universe, so don't worry.

I think it should be dealt with urgently, it is possible that our technology is not as advanced as theirs, and it is very likely to be harmed.

Wait quietly, after all, if the alien technology can come to the earth, it will definitely be much higher than us.

Human beings still have to actively develop their own things, and we must continue to develop for a better tomorrow for human beings.

If radio signals can be deciphered, it means that humans can communicate with aliens.

If a radio signal from space is actually received, humans should first discern the other party's intentions.

I don't think we should respond, because the law of the dark forest in the three-body problem is likely to really exist.

Mankind should do a good job of protecting the earth and developing science and technology.

It is not too late to believe in science and technology, and it is not too late to make a decision when it is confirmed, it may be caused by the action of magnetic fields or gravity.

Possibly, but do you understand?

Well, because your radio can receive a limited number of bands, you may not be able to receive it. But you can also try it.

I suggest you check out the film adaptation of Carl Sagan's name** Touch the Future.

Not necessarily, it could be a machine failure!

On January 9, Canadian scientists received 1.5 billion light-years of radio signals, and in just three weeks, they monitored 13 fast radio pulses (FRBs), according to the BBC, Nature and others, one of which is very unusual and similar to the content characteristics of another previously monitored signal.

This has attracted global attention: Is this a signal from aliens?？As a result of the constant burst of these signals, scientists are curious about what they want to express and are analyzing their situation as if they were telling people on Earth.

The exact location and content of these signals is unknown.

So far, scientists have detected more than 60 "fast-wave bursts", two of which are very similar in content and characteristics, almost identical. Some scientists believe that the enormous energy of the FBR may be caused by the collision of a black hole or neutron star, speculating that it is an anomalous high-energy pulse dispersion outside the galaxy. Some scientists believe that this is just a natural phenomenon, such as a new type of celestial body, or a cosmic high-energy event similar to a "soft gamma repeater" (SGR).

This is a gamma-ray burst phenomenon that occurs every few years. This phenomenon is caused by stellar tremors in "strong magnetars" (neutron stars).

But the concept of time and distance is still far from the current level of science and technology for us, 1.5 billion light years. But does 1.5 billion light-years make sense for an extraterrestrial civilization? Does 1.5 billion light-years mean only 15 kilometers for an alien civilization spacecraft?

Is it possible that the signal from 1.5 billion years ago only represents the signal of an alien civilization 15 minutes ago?

I don't think it's an alien signal, because there's no scientific basis for it.

I think it's important to wait for scientific progress to explain this kind of thing.

I think it's possible, no one knows if there are aliens.

I don't think that's possible, because there's no scientific basis for this kind of thing.
