Rebirth of the Tech Frenzy

Everyone in the conference hall looked dumbfounded. At 50 kilometers per second, this speed has already broken the limit of human aircraft.

The high-speed aircraft is swiftly galloping in space, and the solar panels are also fully functioning. All the data that was previously questioned is now really done.

Graphene, nuclear power, ion engine. And let the space shuttle gallop at such a fast speed.

Everyone looked at the big screen and looked at the data sent back by Hongming. Its speed has reached the escape speed, and it has been accelerating continuously at this stage. This stage is equivalent to the ascent of human launching missiles. Although it has been accelerating, it has always maintained a stable and level flight speed. After all, the power of the battery has always been guaranteed to face the sun. The power supply is always sufficient, and the nuclear power is maintained. The speed is of course very stable and guaranteed. of.

Because it successfully entered the accelerating orbit, and at this stage, the aircraft is no longer orbiting the ecliptic plane, but the vertical ecliptic plane begins to orbit the sun, but the speed is maintained at about 50 kilometers, although it is necessary to keep the engine working. , But this kind of work is no longer the previous breakthrough work, but the speed of the orbit, and this speed can still be increased.

"It has successfully entered the orbit, and the next step is to continuously adjust the flight, so that the speed of the revolution is continuously accelerated, and then when orbiting the sun, when the orbit is far enough out, it will turn to maneuver and fly toward the aphelion again. , Using the height perpendicular to the ecliptic plane to turn to orbit around the sun toward the aphelion. This is equivalent to flying one circle from the Earth’s orbit perpendicular to the ecliptic plane, so that it can be seen as flying out of a circular orbit , When the aircraft orbits the sun and flies out of a C-shaped orbit perpendicular to the ecliptic plane, it suddenly "somersaults" and uses its orbital speed to change directly to the aphelion orbit, which is the orbit that can intersect the orbit of Saturn. In this case, this This flight mode is equivalent to the attitude of ballistic missile flight.

And this kind of flight actually reduces the flight time. After all, there is no need for one orbit to break free. Once captured by the planet's gravity, trying to break free will consume energy again. And this method doesn't consume much, because it still goes around the orbit, and it doesn't forcefully break free of gravity all the time. This orbit scheme using vertical planes is the forward trajectory.

After the spacecraft is far away from the earth, the gravity of the earth no longer interferes with the spacecraft. During this period, it is only necessary to maintain the speed, not to accelerate.

Mona stood up and looked at the display and shook her head slightly and said: "I can't believe it, it really succeeded. The greatest limit of mankind is actually to break through this speed limit. Once it reaches the limit, you can use this gravitational orbit. How did you come up with such a plan when you came to fly? I think you must have thought about it before. You just want our approval. Because you alone cannot be trusted by others."

Xiang Qianjin said with a smile: "In fact, I discovered it accidentally. First of all, inertia. We must first forcefully get rid of the inertia of the earth, that is, surpass the earth's revolution speed, and we are not really launching vertically. In fact, It is the inertial flight along the earth's orbit, but the inertia upwards, not a completely vertical flight, but along the inertial flight angle to revolve around the sun, this orbit is the orbit of the earth and at this time we are looking for After the point where it intersects the orbit of Saturn, you can change the direction and fly directly towards Saturn. This flight is still a stage of escape speed flight. And the speed of flight towards Saturn will be greater! This trajectory is similar to throwing. Like the skipping rope going out, the fixed ends are thrown upwards. This line uses the inertial direction to be the real orbit. After all, it is still using the inertial orbit, and it must maintain an escape speed. In this way, it can fly. Entering into Saturn's orbit, once entering Saturn's gravitational influence zone, it will start to slow down, cut into Saturn's orbit, and start maneuvering to change orbit to capture the catastrophe star!"

Mona nodded and said, "So your goal is to reach Saturn in ninety days, so how fast is the aspheric orbit?"

"Get out of the critical value of the solar system!" Xiang Qianjin said earnestly.

"But we have surpassed the critical value of the universe long ago, and we can surpass it at 16.7." When Mona said this, Xiang Qianjin said with a smile: "Hehe, then I ask you, you are jumping on a galloping train. When going out, do we have our own speed? In order not to fall, do we have to exceed this speed? The minimum speed of the solar system that escapes from the earth is 46.5 kilometers per second, but there is another speed you have to remember, We are still in the spiral arms of the Milky Way, and the sun also has the speed of the sun. We have to escape the centrifugal speed of the sun. Even if we reach the speed, we will still be affected by gravity and will still be caught by gravity. He is always there. .But if you completely get rid of this gravitational force, there is also a speed. If this speed is exceeded, the spacecraft will be directly out of the control of the galaxy. It will be directly thrown out of the solar system. Because the speed is too fast, in that case, the sun If the speed of its own rotation is opposite to the direction of our flight, then we will be farther and farther away. In the end, let alone go to Saturn, the Otter Nebula will not be able to stop us."

Mona suddenly understood, she whispered: "Don't escape the centrifugal speed generated by the sun itself? That is, the speed of 250 kilometers per second?"

Xiang Qianjin picked up a pen and wrote a bunch of formulas on the paper, and then drew a sketch and said: "That's just an estimate, but we had better not exceed 250 kilometers per second. Of course, my predicted speed is 220 kilometers. In terms of speed per second, that is to say, the flying speed of the distant sun, I intend that the sun will throw us out, reaching a speed of 240 kilometers per second or more, and then our spacecraft will turn, gradually decelerate, and maintain the average speed. At 220 kilometers per second, we enter the orbit of Saturn and continue to decrease until we cut into the orbit of Saturn. The whole process can be said to be very thrilling. In order to have enough speed, we must fly at this speed. Going out, this speed is truly out of gravitational control."

Mona stared and asked: "220 kilometers per second?"

"Yes, this is the only speed we can reach Saturn. If it is from the ecliptic plane, there is no way to fly at this speed. After all, the interference of various gravitational forces is really complicated. But our current plan is different. Catastrophic The speed is very fast. It cuts in from the direction of Lyra. Now we know the speed. This guy is flying straight towards us at a speed exceeding 400 kilometers per second. And the speed is increasing. The source of this guy is what we have. A well-known galaxy, this galaxy has always been very famous in China, because every Chinese Qixi Festival pays attention to her."

"You are talking about Alpha Lyra? China's Vega?" Mona heard Xiang Qiang's prompt, and she seemed to have found something wrong. Mona took the paper from Xiang Qiang and said: "This speed is obviously abnormal. Generally speaking, the sun is located on the branch cantilever Orion arm, and the revolution speed is between 240 and 250 kilometers per second, 400 kilometers per second. Obviously not normal. First of all, Alpha Lyra is only twenty-five light-years away from us, and her asteroid belt is left behind by a large group of planets. It is similar to our Kuiper belt. The catastrophe star hits at a speed of 400 kilometers per second. we?"

Xiang Qianjin shook his head. He whispered: "As far as I know, Vega is a main sequence star. Her autobiography is extremely fast. She can spin around in 12 hours. Because of the excessively fast autobiography, Vega is caused. The body shape of Vega is elliptical, because the brightness of Vega is forty times that of the sun, but because of the high-speed rotation, it solves this problem. Vega is surrounded by a large number of stardust disks, so the temperature in the space is higher than the solar system, and Vega is only far away from us. Twenty-five light-years from the environment, Vega’s astrolabe system is most like the solar system, and there is no guarantee that there is no earth in their astrolabe system. So I suspect this is not a simple accident, but a man-made one. Disaster."

"External life? You mean, this is an attack from twenty-five light years away?"

"First of all, biological life can be continued. Human civilization can allow one's own thinking dimensions to continue to expand, from the original few decades to the last 100 years, and then it will gradually improve. So this planet is hard to guarantee. It is not delivered at a very fast speed. Maybe they are using our technology, but their technology is better than ours, using projectile trajectories to let this thing fly into the solar system, and it is precisely aimed at us. Guess Guess why?"

Mona thought for a while, and she said in a deep voice, "Exterminate humans? Did they discover humans?"

"No, I shouldn’t find it. I’m just a personal estimate. This should be a test. This guy should have been sent to us after thirty or more years. This should only be carried out in recent days. In one experiment, this asteroid was probably only launched at the speed of sublight. It should be similar to our probe."

"detector?"

"Yes, it's the same as our Vision, and Voyager. Their purpose is to detect. We are to explore the outer periphery of the solar system and let the spacecraft fly out of the solar system. And they discovered us. A large number of The faint star surrounded by the stars, this faint star is the sun. The characteristic of civilized galaxies is that they should not be in very bright galaxies, because such stars are more aggressive, but ours looks dim, and A galaxy that is easy to be regarded as a variable star is the more likely it is to give birth to life, which is why we can’t find each other. The first is that it’s too difficult. The second is that the distance between us is too far. And it’s more unfortunate. The thing is, we are too close to them. So they are detecting us."

"So our attack will attract their attention?"

"Yes, it will be like this, but because of our attacks inside the galaxy, they will quickly confirm the technological gap between us. For example, their technology can be directly intercepted outside the galaxy. Need to enter the galaxy. So this action of our door will attract their attention. But even if they come, there should be no large-scale army coming. Because they have only used this until now. The detector comes to detect us. What does this mean?"

"It's like us. Although we can send the detector so far, we can't really reach the edge of the galaxy at all."

"That's what it means. There is a lot of uncertainty about their subluminal orbit, and I suspect that their launch was not a success. If it is successful, it should go directly into the astrolabe. Not from the outside. Come in. Of course it has something to do with the Otter Nebula, but his intrusion speed is too fast. This is obviously confiscated, and he should have been caught by the gravity of a certain planet."

"A certain planet? A planet outside of us?"

"Unlike, I think it's a planet in the system."

Mona asked in surprise: "But he is only in the Kuiper belt now? Wait! Kuiper belt! You said there are planets outside the Kuiper belt?! You mean... the tenth planet hypothesis?" (At that time, Pluto Has not been expelled.)

"Yes, but I suspect... this planet is not a planet, but a brown dwarf. That is, a brown dwarf orbiting the sun in the Otter star cluster!"
