There was a powerful explosion in the sixth year of the Ming Dynasty. There has been no conclusion about this explosion. Because of its great power, wide range and strange cause, this incident is called one of the unsolved mysteries in the world. After the big bang, people's first reaction at that time was the explosion of the powder magazine, but as time went on, more and more details surfaced, and people began to doubt the real cause of the explosion. At present, there are three main theories about explosion.

The first argument is the reason that people initially thought, that is, a safety accident occurred in the powder magazine, which led to the explosion of the powder magazine. The center of the big bang is located in a powder magazine. Before the explosion, a large amount of gunpowder was stored in this powder magazine, which would be devastating if it exploded. This statement is also the most credible of all statements, because the powder magazine exploded for a long time in the Ming Dynasty, indicating that the court did not do a good job in preventing the powder magazine, which is probably the direct cause of this big explosion.

The second theory is that it may be because natural gas or biogas leaked from the explosion center, which produced a series of chain reactions. The credibility of this statement is also very high, because according to the records of relevant data, before the Big Bang, there was an earthquake with a smaller magnitude where the explosion occurred, and this earthquake caused the natural gas or biogas originally stored underground to leak out and ignited the gunpowder in the explosive magazine through a series of butterfly effects.

There is also a saying that the explosion was actually not an explosion of a powder magazine, but an explosion caused by a falling meteorite. However, there is no evidence for this statement, but it is just the guess of netizens, because if it is really a meteorite fall, it will definitely leave a crater. However, after field research, no crater has been found, and the ancients will definitely record such a large meteorite fall, but at present, no book has found it, so this statement is not credible.
