In 1957, due to a miscalculation, mankind created a nuclear-powered manhole cover that traveled 206 times the speed of sound

First of all, I would like to ask you a question: Do you know what is the fastest known man-made object in the history of human development today? Probably the first thing that comes to mind for most people on this question is rockets, airplanes and artificial satellites, but in fact, the current human research and development in the field of flying objects is still in the preliminary stage, the speed is not fast, and the fastest known flying object is not made in recent times, but created by the Americans in 1957, is a speed of 206 times the speed of sound manhole cover

In 1957, the staff of Los Alamos Laboratory in New Mexico was planning an underground nuclear explosion test, operation code name "Pascal-A", in short, the experiment consists of, in the specified test area, in the ground to dig a 150 meters deep, the top and bottom of the diameter of 1.2 meters, the bottom widened like a thermometer. The bottom of the widened thermometer-like cave, the planned amount of nuclear material into the bottom and detonated, after the nuclear explosion, the relevant personnel can be placed in the hole detection devices and soil residues to analyze the results of the experiment

However, in order to prevent the leakage of the material, the implementation of this plan also took into account the radiation factor, the personnel who dug the cave at the mouth of the well placed a special cover, this cover is made of pure steel, the thickness of more than 10cm, according to calculations before the test, the nuclear explosion is very small, almost will not affect the ground, coupled with this special cover, almost foolproof

But after the experimenter pressed the button, the results of the display greatly exceeded all expectations, the original was calculated to be a small-scale nuclear explosion, the final release of energy is 5000 times more than the calculated value, a large number of high-temperature airflow down the cave climbing rapidly, and finally at an unimaginable speed instantly rushed out of the hole, and the original inlaid in the hole cover, but also extremely high speed instantly flew to the sky

According to the ultra-high-speed camera set up around the experimental area to capture the image, despite the camera's pixels and capture range, but in a large number of photos, only one of the frames captured the image of the manhole cover, which means that the manhole cover only in the ultra-high-speed camera lens range to stay for a frame of time, and then fly out of the capture range

So what was the speed of this manhole cover at that time? According to the post-test professionals speculate that its speed at least more than 70 kilometers per second, converted to the speed of sound 340 meters per second to see the words, is 206 times the speed of sound, because this initial speed is caused by a nuclear explosion, so it is also known as a nuclear power manhole cover by netizens and scientists, so this raises a question, the last manhole cover where to land?

There are three explanations for this manhole cover in the scientific community, the first is the most likely to happen, that is burning in the atmosphere, because any object in the process of high-speed flight will generate heat, especially in and out of the Earth, the thickness of the atmosphere will block the burning off most of the objects similar to meteorites, except that meteorites are flying into the Earth, and manhole cover is flying out of the Earth, but the results are the same, if this manhole cover is to front If this manhole cover is flying into the sky with a large area exposed, then most likely it will be melted

The second ending is not melted, and fell to the earth, because an object will be obstructed by two forces after rising, namely atmospheric friction and gravity, according to speculation, if the manhole cover is not melted, and the speed can not reach the escape velocity, then it will reach a certain height and fall to the ground

The last and most romantic ending is to fly to the universe. If the manhole cover reaches the third cosmic speed, that is, more than 16.7 kilometers per second, before it rushes out of the atmosphere, it will break the bondage of the Earth's gravity and enter the vast universe, according to the test site at that time, this manhole cover is most likely to fly to the Wuxian system, which is 23,500 light years away from Earth

How about you guys, is it the same as me, did not expect the fastest flying object made by human is actually a manhole cover? But that's the truth, the strange knowledge has increased, right? Don't hurry up and like it!
