1957 a mistake, mankind created the fastest manhole cover, where did it fly?

Among the five probes that can leave the solar system at present, NASA's Voyager 1 is the fastest and farthest man-made object. After being accelerated by the gravity of Jupiter and Saturn, its fastest speed reaches 35 km/s, and after decades of deceleration, its current speed is 17 km/s, and it takes less than 40 minutes to circle the earth at the current speed of Voyager 1.

In addition, although some spacecraft can't fly out of the solar system, their speed is much faster than Voyager 1. For example, Apollo 1 of NASA accelerated to the maximum speed of 70.2 km/s when 1976 was closest to the sun. Parker solar probe, which can be closer to the sun, has the fastest speed at present147 km/s.

But earlier, the fastest man-made object was not a spaceship, but a manhole cover, which was driven by nuclear energy, and the fastest speed reached 66 km/s. Not only that, this manhole cover was also the fastest man-made object, with the maximum instantaneous acceleration reaching 65.438+0 billion m/s, equivalent to 65.438+0 billion g.

So, what does this manhole cover do? Why so soon? Where did you end up?

1957 From May to October, 10 10, the United States conducted the largest and longest-lasting nuclear bomb test in China. Twenty-nine experiments were carried out before and after, and the maximum explosive equivalent of an atmospheric test was 74,000 tons of TNT.

During the experiment, 1200 pigs were used to study the explosion effect. The researchers put pigs in cages and put them in protective clothing made of different materials to test which material has the best heat radiation resistance.

In addition to these routine tests, there will be unexpected situations in the test. In a test explosion, researchers put a nuclear bomb into a pit with a diameter of1.2m and a depth of150m. The top of the pit is a steel manhole cover with a thickness of 10 cm and a mass of 2 tons.

According to the plan, the equivalent of a nuclear bomb is 6 kilograms of TNT. However, I don't know which researcher made a mistake, and the decimal calculation was wrong. The actual explosive equivalent has become 50,000 times as expected, reaching 300 tons of TNT. As a result, this deep pit became? Super cannon? And the manhole cover on it becomes? Shells? .

The shock wave generated by the explosion instantly lifted the manhole cover, and the sprayed flame went straight into the air for hundreds of meters. Because the manhole cover flies too fast, a high-speed camera nearby (shooting one frame every millisecond) only captures one picture of the manhole cover.

Based on this, scientists calculated that the speed of the manhole cover exceeded 66 km/s (240,000 km/h). After the explosion, people never found this manhole cover, so where did it go?

One possibility is that the manhole cover flies very high and then falls far away. The second possibility is that the manhole cover moving at high speed rubs violently with the atmosphere, and the temperature rises to several thousand degrees, resulting in the complete evaporation of the manhole cover.

Thirdly, because the speed of the manhole cover far exceeds the escape speed of the earth (1 1.2 km/s) and the third cosmic velocity (17 km/s), if the manhole cover does not evaporate in the atmosphere, it will escape from the gravitational bondage of the earth and even the sun and fly to distant interstellar space. For a long time, this manhole cover kept the world record for the fastest man-made object.

This manhole cover was launched several months earlier than the first artificial satellite. It may be the first man-made object to fly into space or even the first man-made object to fly out of the solar system. Perhaps it was still flying in space and left the solar system thousands of years later.
