m country, pennsylvania, jwst telescope ground command center

In front of the building, a large flag with a flat earth printed on a white cloth fluttered in the wind. Dozens of young people waved their arms and shouted loudly: "Damn astronomers, how dare you confuse the public with your lies. The earth is flat. There is no earth in the universe."

There are no alien planets..."

"Hang the astronomer!"

"Burn the telescope!"

"Human beings don't need science!"

...

They were so excited that they seemed to be using their sticks to smash the glass door of the center in the next moment, rush into the building, pull out the staff inside and parade them through the streets.

Director Kumar stood in front of the floor-to-ceiling window of his office, but he was not worried at all. Because an orange cordon had already been set up in front of the building, and dozens of heavily armed police were aiming their black guns at the demonstrators.

The cordon is the police's line of defense, and they will not hesitate to shoot any protester who crosses the cordon without permission.

Director Kumar knew this, so he had no worries.

The demonstrators know this too, so they can keep their distance despite their angry expressions.

...

"Honey, where do these cowards come from?" A seductive woman in a tight miniskirt appeared next to him at some point, "What does flat earth mean?"

Her thin lips are as delicate as rose petals, and her long black stocking legs are particularly eye-catching.

Director Kumar couldn't help but swallowed secretly: "Secretary Ruth, this is the office... pay attention to the name."

Ruth's little mouth was slightly raised, and she leaned beside him charmingly, and a crimson fragrance hit her nostrils.

"Dear, there's no one else here."

"Just explain it to me, an ignorant girl..."

Kumar's whole body suddenly went limp, with a look of care on his face: "The demonstrators downstairs are from the Church of the Flat Earth and are a group of anti-scientists."

"What does anti-scientist mean?" Ruth stared with her big innocent eyes and straightened her body.

A beautiful flower is in bud.

Director Kumar's eyes evaded: "Ruth... you should read more newspapers."

"Not everyone in this world believes in science, just take the group of demonstrators downstairs for example."

"They firmly believe that the earth is a flat disk. The center of the disk is the North Pole, and the outer circle of the disk is the South Pole. The Antarctic wraps the ocean, so the sea water will not flow out."

"There is no universe in the world, and there are naturally no so-called aliens, so I am so angry."

Ruth raised her little face, her long eyelashes blinked, and her eyes were full of admiration.

Director Kumar said seriously: "The lack of scientific knowledge has turned them into a group of idiots, so you young people should read more books."

...

"You're awesome!" Ruth lowered her head with a charming face, tapped the floor with the toe of her shoe, and made a "pah...pah..." sound, "It's raining outside now, do you want me to take the umbrella out of the umbrella bag?"

Take it out?"

Director Kumar looked startled, then suddenly understood and looked happy: "Did you bring an umbrella?"

...

The water is like the waves of the eyes, and the mountains are like the gathering of eyebrows and peaks. I want to ask pedestrians where to go? The place where the eyebrows are full.

...

"Beep...beep..."

"Beep...beep..."

There was a rapid ringtone on the phone, and Director Kumar answered the phone angrily: "Henry, you better have a good reason!"

...

"Director, the jwst telescope suddenly received a message from an alien spacecraft!"

Director Kumar was stunned for a moment, then blurted out: "Damn it!" It was unknown whether it was because of the message from the alien spacecraft or because he was interrupted by "good things".

He arranged his clothes in the mirror, made sure everything was normal, and then took out a red pass card from the drawer in his office.

Ruth's eyes lit up, she stepped forward and whispered: "Director, can you take me with you..."

"...I really want to, but...the command and communication room requires Level 1 authority, and you are just an intern secretary." Director Kumar looked embarrassed.

"You just said that young people should study more?" Ruth lowered her head, pretending to be angry, "Besides, you are the boss of the center, don't you have this right?"

...

.

On the large screen in the command and communication room, the simulated image of the JWST telescope kept rotating. Dozens of middle-aged men in blue uniforms frowned and stared at the strange symbols transmitted back from space.

"What's going on?" Director Kumar opened the door and walked straight to Chief Engineer Professor Hunter.

Professor Hunter quickly operated on the keyboard with both hands, "Twenty minutes ago, the avalanche phototube array of the orbiting telescope suddenly received a strange light wave."

"The starting point of this light wave is the alien spacecraft!"

"Aliens actually use light waves to communicate?" This has exceeded Director Kumar's knowledge. As an outstanding astronomer from country M, he has done extensive research on deep space communications.

There are two major difficulties in deep space transmission, one is the cosmic background noise, and the other is path loss.

In order to overcome background noise, humans have to choose extremely high-frequency radio as a means of communication, so that they can "evade" co-frequency interference.

At the same time, in order to overcome the signal path loss of more than 300db, deep space communications can only rely on larger diameter antennas to receive signals, and use larger antenna gains to combat path losses.

Because light waves are extremely easy to lose, in human cognition, it is absolutely impossible to use them as a means of communication, but...

The facts are right in front of you!

"Analysis completed!" Professor Hunter looked at the data on the computer and said in surprise: "Low-frequency light waves!"

"How is that possible?"

...

"Stop worrying about light waves!" Director Kumar asked impatiently: "Send the information to the supercomputing center quickly and ask them to decipher it immediately!"

"I want to know what that damn alien ship is trying to do!"

In fact, as early as 50 years ago, the world's astronomical community discussed what to do when humans on earth encounter alien civilizations. After ten years of research, they came to a consistent conclusion: first, we must understand

Expressions used by aliens to communicate.

The same pronunciation and the same gesture may express different meanings in different places. For example, in most places around the world, a nod means agreement and a shake of the head means denial. But in India

country, nodding to express denial, shaking head to express agreement.

Such completely opposite ways of "expression" can occur among the same biological race. Alien creatures from hundreds of light years must have a "language" that is very different from humans.

Therefore, it is crucial to correctly understand the intentions of aliens.

...Professor Hunter's eyes widened and he stared at the computer screen motionless.

"What's wrong?" Director Kumar realized that things might have changed strangely and looked at the big screen.

Suddenly he uttered an exclamation: "This...!"

"No need to crack it..." Professor Hunter looked depressed and muttered to himself: "Obviously, these aliens are here to destroy the earth..."
