What does ET network language mean?

Aliens.

The meaning of ET is roughly the same as that of Martians, but it is slightly different. ET refers to those who have a high IQ but know nothing about general knowledge. Mathematician Chen Jingrun, for example, knew that he had conquered Goldbach's conjecture, but his life was a mess. In this way, we can call this kind of people ET.

If we say ET people, we should first say "Martians". If some people don't know a thing or knowledge, others can comment as "Martians", which means that people from Mars know nothing about what everyone knows.

Alien

It is the floorboard of human life outside the earth in illusion.

There have been daydreams about aliens in ancient and modern times, but today humans can't actually detect whether there are aliens. Although many people have claimed to have witnessed aliens visiting the earth and even contacted themselves, most scholars and experts believe that the so-called different degrees of contact between humans and aliens is actually a psychological effect. The chances of humans finding "aliens" are very small, and even if aliens are found, it is almost impossible to have any contact with them.

Four-dimensional space theory

Some people think that UFOs come from the fourth dimension. The ghostly aircraft disappeared instantly, and the satellite electronic tracking system network could not be seen at all when it was turned on. It can be thought that UFO residents are playing with space-time technology. A technical means can form some local space bends, and this local curved space will expand in the space in contact with it. After completing this step, people from another space can come to our space.
