At 10:15 a.m. on April 29, 2018, a U.S. "Combat Shadow" test reconnaissance aircraft flew out of the airport.

Two hours later, it was found crashed in the eastern part of the Induocean, about 170 nautical miles from the military port, and the nearest naval base sent a search and rescue force to the area of the accident.

Pilot Bailey parachuted out and was rescued safely.

After checking the cause of the accident, it was found that the reconnaissance plane hit a foreign object at an altitude of 6,000 meters when it was flying at high speed, and its wing was damaged.

The military employees who investigated the accident found it strange that, according to the pilot, no flocks of birds were detected at the time of the accident.

It hit it with a very small thing, just in high-speed flight, it was not expected at all that there would be a foreign object at high altitude, and the joint detector did not detect any metallic reaction.

Fortunately, in the cockpit video, through the reflection of the pilot's visor, a blurry image of the object that hit the wing at the time of the incident was seen.

"It's a stick, it's definitely not a bird. ”

"How can there be a stick at an altitude of 6,000 meters? Could it be that space junk has fallen?"

"Even if space junk falls to the extent that it is 6,000 meters above the surface, even if the surface is not burning, there will definitely be a falling air flow trajectory. ”

"But these don't have it, which means that at the time of impact, the stick was flying sideways in the air? Unfortunately, the video only shows a little bit of it, and it is impossible to judge its trajectory. ”

"Anyway, space junk must have been ruled out, and the reconnaissance plane failed to detect any metal products at the time of the incident, probably because the metal content of the foreign object was too small. And since this is the case, then it is impossible for an item not made of heat-resistant materials to fall from space to a height of six thousand meters, and it should have evaporated a long time ago. ”

Several investigators analyzed it for a long time, but they couldn't figure out what was going on.

I don't know how to write down the cause of the accident in the report, because it is more like it was attacked.

After they honestly reported it, a weapons expert in the military quickly paid attention to the matter.

Dr. Robert said, "It's possible that it's some special stealth alloy material that escaped our joint detectors." ”

"The foreign object itself has propulsion, which makes it rigidly stressed in the unsupported air, and it crashes into the wing. ”

"It may not be an accident!"

The bystanders exclaimed, "In other words, it could be a stealth missile, or a miniature aerial vehicle?"

"It's very likely that this is a new type of weapon that we don't know yet, and theoretically this propulsion is most likely to be the acceleration of the fall, but the video proves that this is not a high-speed falling object, so it must have self-propelled ability, and it should be a flying machine. The doctor said.

Soon, the ships still in the area of the accident reported that no foreign objects had been found in the nearby waters, and there were no fragments of foreign objects in the wreckage of the aircraft.

"It's possible that it's still in the air, sending out more air search forces. ”

Although the flying object was not detected, the planes of the search formation found a foreign object.

Because the speed of foreign objects is supersonic speed, if you search carefully at a certain altitude, you can still see objects that pass through the clouds and cause a sonic boom shock wave.

It's just that this thing doesn't emit any signal, and if it hadn't shot down one of their planes and locked on a general trajectory, it really wouldn't have been able to find it from such a high place.

"It's a supersonic stealth fighter...... No, it's not a fighter, it's too small, it's supposed to be an unmanned aerial vehicle!"

"This supersonic stealth unmanned micro-aircraft technology, even we don't have it, and the volume is too small, how to solve the problem of fuel storage?"

"Is it the latest drone?"

"Chase!"

After spotting a foreign object flying at high speed, the military quickly determined the trajectory of the flight.

A supersonic fighter was sent in pursuit from the military port.

"The target speed is about 500 meters per second, and it is expected to catch up in five minutes. ”

"There is such a high-performance unmanned aerial vehicle ......"

"Its target could be over the base, can it shoot down?"

"No, it's too fast, and the detector can't detect any of its signals......"

The U.S. military quickly sorted out a lot of information about the mysterious flying object.

Although this mysterious flying object is supersonic at speed, it is still far from a real supersonic fighter.

What's really scary about it is its small size and incredible radar stealth capabilities.

If it weren't for the fact that it only flew upright at an altitude of six thousand meters, the trajectory would have been too obvious. Instead, it is pulled up to an altitude of 8,000 meters or even 10,000 meters, and there is no way to detect it.

No electromagnetic waves were detected, not the slightest control signal was intercepted, not even a metallic reaction was detected, and its material was completely unknown.

"Previous footage showed that the wand-like flying object was disconnected several times on impact, so why is it still able to maintain such a high flight speed?" Dr. Robert asked.

"Does it still have nano-repair capabilities?" said the bystander.

Just as they were wondering, five minutes passed in a flash, and a message came from the pursuing plane: "I have caught up with it, its trajectory is very straight, I can attack it, is it allowed to shoot down?"

The doctor said, "Didn't you change course? This might not be a flying machine, but a warhead?"

"Try to be parallel to it and send the image over. ”

Soon, the supersonic fighter approached the target about 20 meters, and if the target exploded within this distance, it would have time to evade.

Under the parallel flight, the image of the mysterious flying object can finally be seen clearly.

After careful observation, the pilot was completely stunned and immediately transmitted the image of the foreign object back to the base.

"What?

The so-called foreign body is a pure carbon arrow.

Because of the previous impact, the arrow had been shattered, the shaft of the arrow was broken into a dozen pieces, and the arrow was detached.

However, these fragments were still stabbing obliquely into the air at a speed of nearly 500 meters per second.

This is completely inexplicable, making everyone in the base who sees this scene dumbfounded.

They were looking for a mysterious flying machine, but they found an even more mysterious arrow.

It's still a broken arrow, obviously there is no jet airflow, and there is no rocket propulsion, but it flies at supersonic speed.

At high speeds, the body heats up noticeably, and a small amount of steam lingers on the surface, but the pure carbon fiber material is very heat-resistant, and less than twice the supersonic speed is not enough to burn it.

"It didn't burn, but it had steam to follow...... Could it be that this vapor evaporated from the previous impact on the 'Battle Shadow', and why did it follow the broken arrow at supersonic speed?"

Dr. Robert looked at the impact in amazement, sensing the absurdity of the picture.

What does this arrow propel?

Why can it still be pushed forward when it is broken?

Why is it that some of the material has evaporated, but the gas can still be promoted?

Where is this inexplicable flight going?

Many doubts suddenly shocked this weapon expert.

Just as there was a dead silence in the hall, a colonel said solemnly: "Dr. Robert, please sort out the information to me, this matter is classified as 3A secret." ”

The doctor said, "Ah? Yes......

The colonel then sent out the information compiled by the doctor, and soon the superior ordered: "Two other supersonic fighters have arrived to pick it up, let the pursuing pilot cooperate in capturing it." ”

The colonel, who received the order, immediately conveyed the order to the pilots in the vicinity of the arrows.

It didn't take long for two other fighters to also run parallel to the arrows.

One of them was an unmanned aerial vehicle that launched a tight net, and in one fell swoop it succeeded in capturing the pile of scattered arrows.

"Slow down!"

The drone began to slow down, but as soon as it slowed down, the drone lost its balance!

The bottom of the plane was straightened with a metal net, and the arrow dragged it to maintain its speed, without dragging it to slow down at all.

"Lose your balance! Lose your balance!"

The dragging plane spun behind the arrow, but no matter which direction it fought, it could not stop the arrow from flying diagonally out of the sky.

Nearby planes that remained parallel measured the speed of the arrow, which was still 500 meters per second.

"Cut the net!"

In desperation, the boss ordered to give up the capture net, and saw that the pile of arrow parts continued to fly with the net, and the unmanned aircraft took a long time to stabilize again.

"Oh my God, what is this?" said Dr. Robert, looking at the screen, a little broken.

I couldn't help but say, "Is this a UFO?"

The colonel shook his head and did not speak.

The commanding superiors also had no news and seemed to be discussing how to deal with it.

The three planes in charge of the pursuit could only keep following, and the time passed minute by minute.

The arrows gradually crossed the American base in the Indoocean, and after a while, the planes could not follow, neither fuel restrictions nor free flight zone restrictions allowed American planes to follow the arrows around the earth.

At this time, Dr. Robert gradually calmed down, and the scholarly instinct allowed him to continue to analyze and think on this absurd basis.

He seemed to think of something, and suddenly said, "Huh, it seems to be chasing the time zone all the time?"

"Time zone?" the colonel was stunned.

Dr. Robert controlled the computer and pointed out the path of the arrow: "If you compare it closely, you can see that it is always facing the sun, and its speed is about 500 meters per second, which is just a little more than the speed of the earth's rotation at 35 degrees north latitude." ”

"The arrow travels from east to west, and if it keeps going at this speed, it can circle the earth once in twenty-four hours. And in the process, almost always at the same time in the local area. ”

He recalled the time when the Battle Shadow was struck, and said, "The time of the impact was just after twelve o'clock in the middle of the day, and the arrows swept through the Indian capital at this speed, and it was twelve o'clock when they reached the west coast. Moving on, across the Indoocean, it will be 12 o'clock in the local area when you reach the sky over the peninsula. ”

The colonel wondered, "What does that mean?"

Dr. Robert shook his head and said, "I don't know, it's like an arrow chasing the sun......"

"Chase the sun, shouldn't the chasing sun fly straight out of the atmosphere, why do you want to circle the earth?" said the colonel.

Dr. Robert seemed to have thought of something, was frantically calculating, and after a moment he stood up abruptly and said, "Actually, it's not orbiting the Earth!"

"I know why it's so fast! It's not following the Earth's rotation, so fast that for us, it's sonic and it's always in the sun. ”

Robert quickly built a model, in which the arrow remained unchanged as an anomaly, while a sphere rotated on the side.

The sphere represents the Earth, and its rotation represents one day, so for that anomaly, one day later, it also passes one circle above the Earth.

"No...... right"

Robert quickly overturned this model, as he discovered that the arrow was not stationary relative to the Earth, and that even after removing the speed of the Earth's rotation, it still had a velocity of a few meters per second.

This speed is exactly the speed at which the arrow moves away from the surface.

In other words, its inexplicable propulsion does not simply come from the rotation of the earth, even if the earth does not rotate, the arrow also has a strange propulsion, driving it away from the earth.

It was supposed to be an arrow flying upwards, because the Earth was spinning, and its rotation speed was significantly faster than its upward speed, which caused it to appear to be passing sideways.

"Stay away from the surface...... Stay away from the surface...... I see!

Robert quickly began to build new models, but he was not very good at the project, he was only a weapons expert.

He could only explain to the colonel verbally: "Colonel, you are right, it is indeed flying 'straight up' out of the atmosphere, but it is too slow! ”

"If an object is in a state of continuous advancement, and at the same time does not exceed the second cosmic velocity, then it will circle the Earth and ascend continuously. ”

Robert casually drew a 'mosquito coil' pattern, and then at the end of the mosquito coil pattern, the line directly pulled out a straight line, symbolizing the freedom from gravitational constraints.

"I can't explain this inexplicable propulsion, but if it can be maintained, its altitude will gradually move away from sea level at a rate of several meters per second, and eventually out of the atmosphere. ”

"For some reason that I don't understand, it's always facing the sun, so it's not following the Earth's rotation, and the trajectory of the ascent is just an illusion of the Earth's self-transfer to what we feel. ”

"When it is detached from the gravitational pull of the Earth, it continues to move towards the Sun in a vacuum...... Advance...... Until the distant future is swallowed up by the sun. ”

The Colonel immediately escalated the idea, and the higher authorities quickly approved it.

An old professor is shown on the screen, facing Robert and saying, "Your idea is right, although it is ridiculous, but it may be the truth, this arrow...... It is rushing unstoppably towards the sun...... At an extremely slow pace. ”

Robert looked ugly and said, "I'm just thinking about it, but it's ridiculous, this propulsion out of thin air allows it to break through the resistance of the air, and the rotation of the earth." ”

"It makes sense to exist, we can only speculate based on the facts, just now, the arrow suddenly rushed to outer space at an extremely fast speed of forty kilometers high, our plane can no longer keep up, fortunately in the capture net, we have placed a detector, it will continue to report to us the position and speed of the arrow. The old professor said.

Robert frowned and said, "Suddenly accelerated? No, doesn't this overturn my conjecture? If it can reach a speed of one second and forty kilometers, why not just rush out of the atmosphere?"

The old professor explained: "No, you are right, it is still not its own speed, but the speed of the earth's revolution...... It's not that the arrow is speeding away from us, it's just that it suddenly doesn't follow the Earth's orbit......"

"As ridiculous as this is, we can only speculate about it. ”

As he spoke, a more rigorous model appeared on the screen.

The old professor said: "The idea of the arrow of the sun you mentioned is one of the dozens of conjectures we have listed, and it is also the most likely one. ”

I saw that on the plane model, a dotted line was drawn between the sun and the arrow, and the revolution of the earth was not a perfect circle. It has a time when it is closest to the sun and a time when it is furthest from the sun.

If the Earth is orbiting close to the Sun, then the arrow will accept the help of the Earth, and the force that pushes itself towards the Sun will superimpose with the force of the Earth approaching the Sun. Make it look like it is following the gravitational pull of the Earth, revolving with the Earth.

It can be seen that the previously observed speed of a few meters per second is not actually its own velocity, but only because the Earth was slightly close to the Sun during that period, and the direction was the same, resulting in the arrows barely moving away from the surface.

But if the Earth revolves away from the Sun, even a little bit, the arrows will not follow. Under these conditions, its propulsion seems to increase by a value of pinch benefit, and after counteracting gravity, it can still maintain its own velocity.

Then, from the observation point of view of the earthlings, the arrow will suddenly move away at a very fast speed.

In fact, the arrow did not accelerate, but the speed of the earth was too fast, and the two parted ways.

"The distance between the arrow and the sun is not increased by the gravitational pull of the earth, but on the contrary, the arrow is always oriented towards the sun and decreases the distance from the sun at an extremely slow rate...... This value, calculated to allow the arrow to fly in a vacuum at a speed of forty-five meters per second, approximately after throwing away all influences. ”

"To put it simply, no amount of tugging on this arrow can stop it from flying towards the sun at a speed of less than forty-five meters per second, on the contrary, it is possible to help propel it. ”

"Whether there is a way to stop this unstoppable 'constant propulsion', we can no longer explore, it has moved away from the earth. ”

Speaking of this, the old professor was stunned for a while.

Robert was also a little distracted, he had been engaged in engineering all his life, and he had never seen such a strange thing.

It's ...... It's simply an alien product.

After the serious thinking based on the absurd reality ended, he began to fall into a state of partial collapse of his worldview, and the physics in his heart was destroyed by this arrow.

No matter how well it is analyzed, it can't stand its basic premise that it is fundamentally broken!

Neither classical nor subversive physics can explain this strange phenomenon.

"God, where did this arrow come from?"

......
