What makes scientists give up explaining?

Nature is full of mysterious forces, and scientists have given up explaining too many events.

I've been wanting to talk about the big bang in China for a long time. China Wang Gong factory explosion in Ming Dynasty. 1626, at 9: 00 a.m. on the sixth day of the fifth lunar month in the sixth year of Emperor Xizong of the Ming Dynasty, there was a Wang Gong factory producing gunpowder in the capital at that time, and there was a sudden continuous thunder and lightning nearby, but the gunpowder did not explode. All 30 gunpowder workers in the maharaja factory died, but only one man named Wu Er survived. Endless smoke hangs over the sky, and all kinds of strange clouds and strange fog rise into the sky. Houses 3 kilometers northwest were shattered, and tens of thousands of houses and 20,000 people in Fiona Fang 7 kilometers were blown to pieces and fell from the air. And all the clothes, the trees flying to the western hills. In the Ming Dynasty, Li's investigation and statistics reported to the emperor: "More than 30 houses collapsed 10930, with 537 deaths, with a diameter of 1.5km and an area of 2.25km2". There is no reasonable explanation for the cause of the explosion so far, and there are different opinions about earthquakes, tornadoes and meteorite impacts, which are not convincing. The Wang Gong Factory Big Bang, the Indian Mountain Death Incident and the Tunguska Big Bang are also known as the mysteries of the three major natural disasters.

The Death Mountain Incident in India 4000 years ago. It was discovered in Mohenjo Rhoda, India on 1922, and a bustling city site was destroyed in an instant. The city was destroyed by an explosion at a moment 4000 years ago, and all the houses within the explosion diameter 1 km were blown to ashes. However, the city residents died suddenly at some point 3600 years ago. Judging from the remains, they were unprepared before they died, and there were shock waves and radiation residues, which were obviously caused by nuclear radiation. The signs of urban destruction and death are very similar to the atomic bombings in Hiroshima and Nagasaki. Did India have nuclear weapons like the atomic bomb 4000 years ago? 1908 The Tunguska Big Bang in Russia is well known, so I won't repeat it.

There is also a knife-shaped boulder engraved with mysterious rock paintings in the Tema Oasis in Saudi Arabia. There are also the Sun Gate on the 4,000m plateau in Bolivia and the lower city on the island of that country ... There are countless natural phenomena that scientists give up explaining, but with the unremitting exploration of scientists, these secrets will be revealed to the world one day!
