If the end of the world comes
Many so-called prophecies say there may be an end to the world in the future. Seeing such a prophecy, I will think that this is not nonsense, I can also predict the future of the universe will perish, but how long this future is, I just don't say!
There is another kind of person who "predicts" the specific year of the end of the world, and to put it bluntly, isn't this speculation? It's about the Indian prodigy, the Russian Martian boy, the Great Bulgarian prophet Babawanga.
However, in this issue, let's talk about it from another angle, if the end of the world really comes in the future and human beings suddenly become extinct, can human beings leave traces?
Do humans leave traces?
Some people say that plastics invented by humans are not degradable? Plastic should be able to stay, right?
However, the essence of plastic is polymer organic matter, although it is indeed difficult to decompose, but it is not non-decomposable, as long as it is organic matter, it will eventually be decomposed by the earth. It's just that this time may be thousands or tens of thousands of years, but this time is simply not worth mentioning compared to the life of the earth.
What about glass? Glass is an inorganic substance, it should be able to stay, right?
Theoretically, glass is not degradable and has the opportunity to stay and be discovered by "other civilizations".
But in fact, the earth's geology is not static, the material in the earth's crust will be squeezed, which will also be why the fossils found by archaeologists are incomplete, because with the movement of the earth's crust and fragmentation, glass is fragile, hundreds of thousands of years, millions of years later, glass will turn back into sand.
Only one trace of humanity will remain on Earth
Plastic and glass have been excluded, so has there ever been a human invention that has been passed down for hundreds of millions of years?
The answer is yes, and that is the metal components in electronic products. It is the metal wire sandwiched in the middle of the silicon wafer, the main component of the silicon wafer is silicon dioxide, and the sand is the same, so the silicon wafer can be stored for a long time, at least for hundreds of millions of years is not a problem. If these silicon wafers wrapped in metal components were buried under the soil layer in the first place, they could even be preserved for more than a billion years.
If, hundreds of millions of years later, the earth has evolved new intelligent species, when they dig up the chip invented by humans when they are archaeology, they may understand that the earth once had an anthropocene.
