Doomsday

It took about two hours for the alien to stop looking at the computer.

"We can start communicating. Time is tight. Time is waiting. Time flies. Time ... sorry. Please wait. I need to adjust."

After a few moments, the alien said again in a hurry: "Danger!"

I said the word "dangerous", and the aliens said nothing. After a while, watching a group of people looking at themselves, the alien said again, "Sorry, I need to adjust again."

After a moment again, the aliens spoke at a slow pace, with a calm tone of voice: "Hello, now we can start communicating. First of all, I want to explain, from ..."

Stuck again.

Wang Wanghu said in a tentative tone: "What aliens do you want to say?"

"Yes, your naming of the galaxy is very different from ours. I need to adjust it a little bit and explain it in a way that you can understand. Please wait. Okay."

After waiting for about a minute, the alien said again in a very calm tone: "I already have a preliminary understanding of earth civilization. According to your exploration of the universe, the enemy aliens are from the Serpent, according to the Flanders star. The nomenclature of the 55th Serpentine Planetary Serpentine is 4,600 light years from Earth. "

No matter if you understand or not, you just nodded.

"According to Earth time, the star system of Serpentine Serpent 55 began to explore outer space 11 thousand years ago. When we monitored that this civilization began to try to leave the home star, their spacecraft could reach the speed of light of 40,000. One-half, but soon, according to the division of speed by the earth's civilization, they exceeded the speed of the third universe and reached 1.4 times the speed of light. "

Wang Hu looked at a young officer behind him. The officer quickly said: "The first cosmic velocity is the velocity of the surrounding earth, 7.9 kilometers per second, and the second cosmic velocity is the velocity of gravity away from the earth, 11.2 kilometers per second, and the third cosmic velocity. It is out of the gravitational velocity of the sun, 16.7 kilometers per second. "

Wang Wanghu nodded, and then he said anxiously to the alien: "Can I ask a question?"

"can."

"What is the speed of the Serpent aliens now?"

"The speed of light is a universal speed-measuring unit for advanced civilizations in the universe. The fastest speed of the Stellar planetary civilization of 55 Serpents now reaches 31% of the speed of light."

的 One third of the speed of light is about 120,000 kilometers per second.

十二 120,000 kilometers per second.

The fastest spacecraft for humans has not yet reached 16.7 kilometers per second.

Wang Hu was silent, everyone was silent, and after a moment, Wang Hu whispered, "How about you? How fast are you?"

"Sixty-five percent of the highest speed of light. The speed of spacecraft currently in common use can reach as fast as fifty percent of the speed of light."

He is more advanced than the Serpent.

笑 A smile appeared again on everyone's face.

But Gao Yuan always remembers the danger said by the aliens, but his status is too low, and it is not good to cross Wang Hu's question now.

King Wanghu pondered for a moment and said, "So how are you going to deal with the aliens of the Serpent? Can you help us fight back their aggression?"

The alien was silent for a moment, and then he said in a calm tone: "I can't fight back the aliens of the star planetary system of Serpents 55, in order to get rid of Serpents ..."

Wang Wanghu was a little embarrassed and said, "Can you just call the snake man? Save a little ..."

"About five days before Earth time, my spacecraft was discovered by the Serpent Man and intercepted me. In outer space, they could not pose a threat to me, but after entering the Earth ’s atmosphere, our speed was basically the same. In order to get rid of the Serpent Man Interception, my spacecraft has crashed, so I can only help the Earth ’s humanity, and I cannot directly help you fight back the invasion of the Serpent. ”

Heartbroken, so it was a long silence.

Wang Wanghu sighed and whispered, "Are you ... no more people coming? May I ask, you are from that planet, what kind of civilization is your civilization?"

This alien change is silent.

Ye Wanghu quickly said, "Even if it is not convenient to answer, just when I didn't ask."

"Our civilization has been destroyed. Our mother star is from the Milky Way, a planetary system 6300 light years away from Earth. About 5,000 years ago, our mother star was destroyed by a supernova explosion. The Earth observed and recorded This time the supernova broke out, and in May of the first year of the year, it went out to the east in the morning and guarded the sky. The day is too white, the horns are around, and the color is red. "

Everyone nodded together, only the history professor said loudly: "I know, I know! It is recorded in the book" Song Hui Yao "."

The aliens continued calmly: "At the time of the demise of our mother star, we were already capable of large-scale interstellar immigration. Our new home is in the Milky Way, which is 1,800 light-years from the earth. The planet has not recorded our planet System, that's because, when you started to have enough ability to see our planetary system, our planetary system once again perished. "

Everyone was sluggish together and perished twice in a row?

"Why perish?"

"War. Civil War."

The aliens no longer say more, and Gao Yuan also issued a sad and regretful sigh together.

The key is that no one came to rescue ...

"Different from the disaster caused by the first supernova explosion, in the second disaster, the subject of our civilization failed to escape, so our civilization has been functionally extinct, leaving only about 10,000 people to remain in every corner of the universe, just like Like your astronauts, you drift in the universe, but now, the Serpent Man has become our common threat, because after occupying the Earth, the next goal of the Serpent Man will be our new home. "

What did you say?

I really have nothing to say.

Wu Gaoyuan pretended to dare to interject, "Can we possibly defeat the Serpent?"

"Have."

Gao Yuan immediately said: "How likely is it?"

The aliens were silent. At this time, Gao Yuan could not help but said, "Is it impossible to defeat them at all ..."

"This question requires a precondition, and that is whether you are asking the Serpent Expedition or the subject of civilization of the Serpent."

"Discovery team?"

The aliens said very calmly: "The Serpents who came to Earth today left the mother star 7500 years ago, at a speed of 22% of the speed of light. Now, the speed of the Serpents's expedition spacecraft At 31 percent, it has three habitable planets, and the population is uncountable. "

A military officer asked in confusion: "Is this time right?"

The alien still said very calmly: "In the wormhole, the astrophysics of the earth, the description of the wormhole is basically correct. This expedition team started from the third planet of the Great Serpent, five thousand five hundred light years away. But there are wormholes, so they only need about 2,000 years to reach Earth from the third planet of the Great Snake Man, and our planet has no wormhole to the earth, so we are closer and faster, but it takes time But it ’s even longer ~ www.wuxiahere.com ~ Messed up, all messed up. When the concepts of time, distance, and space are related to the wormhole, Gao Yuan immediately gave up the relationship between time and distance in the conversion, he did n’t That brain.

At this time, Wang Hu whispered, "You mean, it's just an expedition that is invading us now?"

"Yes, it's just an expedition, a mother ship of two basic units, used to explore the habitable planet found. If it is confirmed that it is suitable for the survival of the Serpent, then it will occupy this planet. If there is a higher civilization on this planet, then first Destroy the civilization of this planet. "

After speaking, the alien was silent for a moment, and then he said loudly: "According to our ... the earth does not have this word and cannot be accurately expressed, it can be called a space observation device. According to the discovery of our space observation device, the big snake man The main civilization has already set off from the home star, and according to their speed and the impulse available on the way, they will arrive 320 years after Earth time. "

King Wanghu rubbed his chin with his hand, and then he said very bitterly: "Fly for thousands of years just to occupy our planet? Where is the earth ..."

"Every planet in the universe that is suitable for its own civilization is extremely precious. It is a carbon-based creature that is highly similar to the Serpent, which is your greatest misfortune."

Wang Wanghu was silent for a moment, and then he said to the aliens: "So what about you? Are you also carbon-based life? Are you looking like you now? Or a space suit or any other equipment?"

"This is a space suit, a personal aircraft, an escape capsule, a tool suit that communicates with lower civilizations, a protective layer, and a collection of other functions ... shell, please let me find a suitable word, find it, use one of you Easy to understand vocabulary, this is mech. "
