Why is the ever-burning lamp in Zhuge Liang's tomb immortal for thousands of years?

Zhuge Liang gave everyone the impression that he was resourceful and a very legendary figure. Legend has it that the ever-burning lamp in Zhuge Liang's tomb is still on after thousands of years, which is the inheritance and extension of his legend. Perhaps Zhuge Liang himself is resourceful, so he has the ever-burning lamp that lasts for thousands of years? This is a legend and an illusion. So is there really a ever-burning lamp in the world? Is the ever-burning lamp really immortal for thousands of years? We discuss it in two situations.

Let's talk about the ever-burning lamp in the folk mouth first. As the name implies, the ever-burning lamp is a kind of lamp that can burn all the time and always be on. It will never go out, and it may last for thousands of years, thousands of years, or even hundreds of thousands of years. Really? There may be, but the premise of combustion is that there is enough material and air to support combustion. In order to make the lamp last for a long time, I think someone has to take care of it all the time, guard it day and night, and constantly add materials to make the burning always happen under air conditions. 365 days and 24 hours, round and round, full of children and grandchildren. What an ideal idea, the possibility of realization is too small. Our science tells us that such an ever-burning lamp can only exist in our imagination, but it can't be realized in reality.

Let me talk about the ever-burning lamps excavated in history, such as the ever-burning lamps in Zhuge Liang's tomb. Why can these lamps burn for thousands of years? This is just an illusion. In the ancient tomb, relatives would light this lamp when the tomb was closed, thinking that it would be convenient for the deceased to get up at night and have a snack. However, thousands of years later, people opened the grave and found that the light was still on. This lamp was lit thousands of years ago! So the ever-burning lamp came like this. We know that combustion cannot be carried out in a vacuum. One day, after the tomb is closed, the oxygen in the tomb will burn out and the lights will go out. The ever-burning lamp is filled with fuel with low ignition point. At the moment when the tomb was opened, air entered and the ever-burning lamp was rekindled, which made future generations think that it would last for thousands of years.

These are two reasons why the ever-burning lamps in Zhuge Liang's tomb can last for a long time.
