Scientists believe that cosmic people should be more advanced and developed intelligent creatures than earthlings, so their language should also be developed. One of the signs is the high mathematicization of language. Therefore, scientists try to use mathematics to express language, which is the basic idea of universal language.
Froden Searle, a Dutch scholar, once put forward a design method of cosmic language. Based on mathematical symbols, he has a set of rules and codes, and uses mathematical methods to express syntax. His basic information operation is very simple. Zhou Haizhong, a mathematician and linguist in China, pointed out in the article Cosmic Linguistics published in 1999 that mathematical language has the characteristics of accuracy, conciseness, abstraction, logicality, universality and formalization, and is an ideal tool for cosmic communication.
History of cosmic language research
18th century and19th century, before people knew whether there was life on Mars, there were many ideas to communicate with Martians, including cutting down forests in Siberia on a large scale, forming visible geometric shapes on Mars on the ground, and sending Morse code into space. Most of these ideas remain in the theoretical stage.
Some scientists think that a "universal language" should be designed. As early as 1896, Francis Gordon, a mathematician and anthropologist, made a discussion on this aspect. They pointed out that in a developed civilized society, mathematics must be the crown of science. Without mathematics, there would be no civilization. Therefore, it is ideal to express language in a mathematical way, which is most easily accepted by aliens.
Dutch mathematician Hans-Freud Densal followed this idea and formally designed a "universal language". He pointed out that all intelligent creatures can understand the basic mathematical concept of 1+ 1=2, so it is possible to design a general mathematical language that everyone can understand. We can express different meanings by emitting radio waves with different wavelengths. Short radio wave signals can be used to represent numbers, long radio wave signals can represent addition and subtraction symbols, and different combinations between them can be used to represent different meanings.
