Hawking once issued a serious warning when he was alive. The reason was that the radio telescope "Sky Eye" received a suspicious signal from outer space 4 light years away.
After learning the news, Hawking solemnly warned: "Don't answer! Don't answer! Don't answer!"
After careful consideration and analysis of the various possibilities of contact with extraterrestrial civilizations, the government decided not to miss this once-in-a-lifetime opportunity, and pointed out that this communication might trigger a great leap forward in the technology of all mankind.
So it was decided to answer.
After that, scientists announced the discovery of the layered structure of the sun, which can be used as a radio wave amplifier to amplify human signals and send them to the universe.
Then, Hawking warned again: "Don't answer! Don't answer! Don't answer!"
Later, he used the sun to reply to a message in the direction of receiving the signal 4 light years away. The content included an overview of the earth planet, a summary of the earth's life system, and basic information about world history. The total information was 17.5KB.
Historians named this day "Reply Day".
A few days later, radio stations around the world simultaneously received tens of thousands of cosmic signals, all from the same direction four light years away. Faced with such abnormal signals, humans finally realized the danger and fear.
The United Nations held an emergency meeting to jointly study the deciphering of alien information and announced that the world was on a war footing.
During this period, the Earth continued to receive a large number of alien signals every day. The United Nations Alien Information Deciphering Team was established, bringing together all the world's top scientists, and immediately devoted themselves to the deciphering and translating of these tens of thousands of alien information.
The United Nations determined an international cooperation plan and officially launched the Human Escape Plan. Countries formulated economic savings plans, population control plans, and began to devote all their efforts to the research of aerospace technology and the construction of space fleets.
At this time, the Earth received more and more alien signals every day. Humans knew that they had little time left.
The Alien Information Deciphering Team announced to the outside world: The deciphering program has finally been successfully developed!
In the conference room of the United Nations Building, the heads of state stared at the screen nervously. The program showed that these tens of thousands of alien signals were all the same information. As the computer deciphered, a line of words was clearly displayed on the screen. Humans finally read the letter from another world in the universe for the first time:
Do you get overtime pay for overtime work over there?
