Everlasting lights often appear in novels. Does it really exist, and how does it keep the lights on?

In many novels based on ancient times, there will be a noun—eternal light, which is usually associated with ancient tombs. Legend has it that this kind of ever-bright lamp can be immortal in the ancient tomb, always illuminating the tomb, but even the electric lamp will go out after losing the shop, not to mention the ancient ever-bright lamps that relied on lamp oil, which often appeared in these novels. The ever-bright lamp, does it really exist, and how does it keep it bright and not extinguished?

According to historical records, there was a permanent lamp in the Mausoleum of Qin Shihuang who was refined into kerosene to ignite. This permanent lamp can burn for more than 5,000 years. However, people have not yet been able to unearth the Mausoleum of Qin Shihuang, so this record cannot be ascertained as it is true. But in the Dingling Tombs of Beijing, I found an ever-bright lamp. It is not so much a lamp as it is a lamp, because it uses a large blue and white porcelain cylinder to hold the oil, and there is a long wick inside. Obviously this This is the true face of the Dingling Everlasting Lantern, but it is a pity that the Everlighting Lantern went out.


However, this also proves that the eternal light in the novel actually exists, and the principle of extinguishing it is also very simple. First of all, if you want to keep the lights on, you need enough fuel, and second, you need enough oxygen. In places like the underground tombs, the space is relatively closed, and the oxygen will be quickly consumed, so keep the lights on. It is very difficult. Secondly, no fuel has been found that can burn for thousands of years at the current location. Even the most durable fuel, whale oil, can only burn for 14 years.

Through research, it is found that the secret of the long-brightness of the long-bright lamp lies in the wick of the long-bright lamp. Scientists have discovered that the wick of the long-bright lamp contains white phosphorous. Therefore, the lantern was already extinguished when the tomb was depleted of oxygen. When the tomb was opened again, the wick of the lantern would be lit again when enough oxygen was in contact with it.


From this point of view, the ever-changing light is just an illusion that people have seen, but we still have to admire the wisdom of the ancients. We can find such materials to make lamps. This is a bit like modern smart lights. , When there is no one, it will go out by itself. Moreover, it saves more manpower and financial resources to make the lantern. It is worth mentioning that the ancients used white phosphorus to make the wick can also play a role in preventing people from robbery, because white phosphorus will emit toxic gas after burning, which will endanger people. Life.

Most of the large underground tombs are buried with emperors of various dynasties or well-known local officials. The use of eternal lights can not only play a decorative role, but also play a role in preventing tomb robbery, which can be said to kill two birds with one stone.
