According to Records of the Historian, the ever-burning lamp in Qin Shihuang's mausoleum "takes mermaid cream as a candle, which will last for a long time." Similar records also appear in other ancient books.
It is described in the novel that when the tomb was reopened by uninvited guests thousands of years later, the ever-burning lamp suddenly lit up and gave off a strange light. ...
When people are nervous, they will also feel confused: hasn't this lamp been out for thousands of years? Physicist Joule may disagree! The law of conservation of energy fails on the ever-burning lamp? What principle has kept it working for thousands of years?
Is mermaid cream a kind of fuel with eternal energy, which can make the lamp never go out? Break our common sense? But as we all know, combustion needs oxygen.
This seemingly simple question has been studied by experts for a long time and finally discovered the secret of how the ever-burning lamp works.
In fact, it went out at the moment when the oxygen ran out after the tomb was closed. This is in line with scientific principles!
Then why is there a phenomenon of "longevity"?
This is because when the sealed tomb is opened, the air immediately fills it. There is white phosphorus in the wick of the ever-burning lamp
We know that white phosphorus has a low ignition point and is prone to spontaneous combustion, so the light is on again.
This is the secret of the so-called A Ring of Endless Light. The working principle is actually very simple, but it contains the wisdom of the ancients.
With the development of some crafts and technologies, people who want to continue to enjoy the splendor when they are alive after death never thought that they would be stripped of their graves and dried!
