The mystery of the Wanggongchang Explosion

Ancient Chinese figures regard a small gunpowder explosion.
Ancient Chinese figures regard a small gunpowder explosion.

In the spring of 1626, during the reign of the Tianqi Emperor — the last ruler of the Ming dynasty — a catastrophic explosion devastated Beijing. As many as 20,000 people were reportedly killed, and entire square miles of the city were completely obliterated. Yet despite the large scale of destruction, and the generally meticulous recordkeeping of the imperial court, the cause and nature of the explosion are still subject to fevered speculation. Some even suggest that it never actually occurred at all.

The earliest account of the event appears in an official gazette (dibao) from the summer of 1626, reprinted later under the title “Official Report on a Heavenly Incident” (see Feng 2020):

When the sky was bright and clear, there was a sound like a roar from the northeast to the southwest corner of the capital, and the ashes rose and the houses were uprooted. In a moment there was a great earthquake, and the sky and the earth collapsed, and it was dark as night. From Shunchengmen in the east to Jinbu in the north, three to four miles in length, the surrounding area was destroyed, affecting tens of thousands of homes and people. The area around Wang Gong’s factory is completely devastated, with pieces of corpses everywhere, a suffocating smell filling the air, and rubble falling from the sky, confusing the vision. It is difficult to describe this heartbreaking sight. The roar of the explosion was heard from Hexiwu in the south, in Tongzhou in the east, in Miyun, and Changping in the north.1

Feng (2020, p. 74) notes two ways that this report differs from “conventional” gazettes:

The first is that it includes no reference to imperial edicts or court memorials; instead, it features copious entries describing how people, including the emperor and officials, suffered from the catastrophic explosion. Second, the text delineates an extensive array of abnormal and uncanny scenes that occurred in multiple locations across Beijing, conveying an atmosphere of panic in the capital. These elaborate narratives of “strangeness” stand in sharp contrast to the typically terse accounts of disasters in other gazettes.

Setting aside these reports, the simplest explanation for the explosion is not so strange at all: an accidental ignition of stores at the Imperial Gunpowder Workshop (Wanggongchang). Indeed, the Wanggongchang Armory, which produced nearly two tons of gunpowder per week2, was located near the epicenter of the blast. Yet while this account might seem to accord with the principle of Occam’s Razor, some argue that the details don’t add up. In particular, analysis suggests that the destruction described in contemporary records would have required explosive force equivalent to 20,000 tons of TNT, orders of magnitude more than even the largest plausible stockpiles of black powder could produce.3 Others contend that specific elements of the official narrative (a “roaring rumble” from the northeast, a bright streak of light, mushroom-shaped clouds) are inconsistent with a gunpowder explosion.

Alternative explanations abound. A 1986 conference in Beijing

explored all the possible causes of the incident from a spontaneous explosion of black powder to a natural gas leak, and the more far-fetched theories of meteorites, hidden volcanoes, and an underground nuclear discharge. The conference participants ultimately concluded that an earthquake resulted in a release of gasses at the site which ignited a massive explosion and firestorm which destroyed the area.

Other more “outlandish” theories, Jeremiah Jenne notes, “have implicated supernatural forces and even an interplanetary nuclear strike on Beijing.”

The reality may be far more mundane than any of the above. Feng (2020) argues that historical accounts of the explosion immediately sought to “politicize” it. In fact, the Tianqi Emperor was not a popular figure. He was, as Jenne recounts, “an odd young man, more comfortable in a carpenter’s shop than reading documents. […] Power devolved to his mother and the eunuchs, in particular, the infamous Wei Zhongxian, one of the most corrupt officials in Chinese history.” Along these lines, Feng suggests that “the ‘Official Report’ emphasizes the strangeness of the explosion in a manner that subtly aims to provoke the audience’s suspicion of the eunuch faction.” Perhaps the real story, then, is one of exaggeration for political effect — an industrial explosion embellished and distorted to tar a distrusted group.



Mysterious lake appears in the middle of the desert, without explanation

We bring you the latest in our ongoing series of stories about lake-related mysteries: apparently, a large, deep lake has unexpectedly (who ever expects this sort of thing?) materialized in the middle of the Tunisian desert.

Our North African correspondents write:
The lake is just over a hectare in size and 10-18m deep. It is presumed that a small earthquake fractured a natural dam holding an artificial reservoir allowing the water to reach the surface. However, the aquifer has not been found – the theory relies more on the absence of other credible explanations than anything else.
More troubling than the lake’s unexplained formation, perhaps, is that people are flocking to swim in it — despite potentially grave dangers. The lake, it seems, may harbor potentially toxic algae — and, due to the presence of nearby phosphate mines, the waters may be radioactive.

Mysterious object spotted in lake on Saturn’s moon

Titan, the largest moon of Saturn, is notably the only known extraterrestrial body where surface liquid exists. In its case, the liquid is not water but rather liquid methane. Titan hasn’t just got a few puddles here and there, either: it has veritable seas of liquid methane covering large parts of its surface. And at a balmy -180 degrees Celsius, they make for the perfect beach vacation!

Recently, scientists have been puzzled by th

e appearance of a large object in one of Titan’s methane lakes:

They spotted the object in an image taken by Nasa’s Cassini probe last year as it swung around the alien moon, more than a billion kilometres from Earth. Pictures of the same spot captured nothing before or some days later.
Little more than a white blob on a grainy image of Titan’s northern hemisphere, the sighting could be an iceberg that broke free of the shoreline, an effect of rising bubbles, or waves rolling across the normally placid lake’s surface, scientists say.
Astronomers have named the blob the “magic island” until they have a better idea what they are looking at.

Personally, I prefer to believe that the Sirens of Titan are somehow involved. At any rate, you can read more here.
