Alien signal? Do not answer! Do not answer! Do not answer!

what happened?!

According to a report by the British Broadcasting Corporation (BBC) on the 9th, astronomers published a new study in Nature: a telescope in Canada captured 13 fast radio bursts in two months, one of which was very different. The ordinary repeated waves, this wave comes from 1.5 billion light years away. Scientists say that it is impossible to rule out the possibility that this wave is from an alien spacecraft.

According to the report, one of the 13 fast radio bursts is unusual. It comes from 1.5 billion light-years and is the second to find repeated waves. Previously, researchers used the same telescope to capture the same waves.

Captured by this wave is the Canadian Hydrogen Intensity Mapping Experiment (CHIME) radio telescope. Located in the Okanagan Valley of British Columbia, it consists of four 100-meter-long semi-cylindrical antennas that scan the northern sky every day. The telescope was launched last year and detected 13 radio bursts shortly after its activation, including this repeated radio wave.

“The second capture of repeated waves means that we may still capture more from there,” says Ingrid Stairs of the University of British Columbia's astrophysicist. “With more repetitive waves and more Resources for research, we may be able to solve the mysteries of these universes: Where did these waves come from, and what caused them."

Tendukal of McGill University in Canada also said: "We found repeated radio waves whose properties are very similar to those of the last wave. This gives us more information about the overall characteristics of these waves."

The BBC said that there are various theories that explain the sources of these cosmic waves. For example, these waves may come from a neutron star with a strong magnetic field, possibly by combining two neutron stars.

The picture is a highly magnetized rotating neutron star. Astronomers say it may be the source of radio waves.

However, some observers believe that these waves are actually from some sort of alien spacecraft.

Then the question comes: Should we respond to these signals?

We expect that the development of science and technology will discover other life in the universe, and let us feel that we are not alone in the universe.

If we respond and get a reply from the same source, then there is no doubt that it will bring unprecedented leap to our current scientific work!

However, don't forget that the famous scientist Hawking has repeatedly warned mankind: I hope that the radio telescope that can monitor the cosmic signals in the world should not answer any suspicious signals. Do not expose the existence of human civilization without understanding the other's intentions.

"If aliens really visit Earth on a day-to-day, I think the results are similar to those when Columbus arrived in the American continent, which is not a good thing for Native Americans."

Friends who have seen "Three-body" are no strangers to this story:

Aliens have discovered that there may be Earth and want to locate the Earth. One of the kind-hearted aliens secretly warned the earth: "Don't answer! Don't answer! Don't answer!" The signal was misunderstood. Humans responded to these signals, the earth was found, and then...

At present, for these mysterious radio waves, the response of netizens is basically divided into two factions:

One fact is: can't respond! If the response signal is received by a civilization that is much more developed than our human science and technology, will human beings fall into the crisis of foreign civilization invasion like the Three-body?

Another fact is: Hurry up and reply! I have already lived enough! I don't want to take the exam! Give it to the three-body civilization...

Some media interviewed Liu Cixin, a science fiction writer and author of "Three-body", on this issue. He said that whether the response should be decided by the international community.

In addition, Liu Cixin also pointed out that most of this kind of radio wave proved to be a natural phenomenon, at least not only can be sent, so as far as he is concerned, he may not reply, and listen to collect more information before making a decision.

So this "extraordinary friend", do you think we should reply to add?
