Why is mathematics the universal language of the universe?

Mathematics has become the preferred language of the universe and has been sent to extraterrestrial planets many times.

Galileo, an Italian philosopher and astronomer, once said, "Mathematics is the language used by God to write the universe". Based on this idea, carl sagan, an American astronomer and popular science writer, is convinced that no matter how different the technological civilizations in the universe are, there is a common language-mathematical language. Zhou Haizhong, a mathematician and linguist in China, believes that mathematical expression is accurate and concise, logic is abstract and universal, and form is flexible and changeable, which is an ideal tool for cosmic communication. Therefore, mathematical language has become the preferred universal language for human beings.

1960, Hans Frodden Searle, a Dutch mathematician and astronomer, published a classic monograph entitled Cosmic Language: A Language Designed for Intercosmic Communication. He designed an artificial language based on mathematics-LINCOS, which has a set of rules and codes, constructs sentences by mathematical and logical methods, and expresses different meanings by emitting radio waves with different wavelengths. For example, short radio wave signals can represent numbers and long radio wave signals represent addition and subtraction symbols, and different combinations between them can be used to express different meanings. Frodden Searle believes that the communication with aliens should be gradual, from shallow to deep, starting with the most basic mathematical concepts, and then gradually expanding to complex cultural concepts.

Canadian astronomers Ivan Datie and Steven Du Masi improved Frodden Searle's cosmology. In 1999 and 2003, they sent messages containing their own designed mathematical language to distant planets through radio telescopes, hoping that the aliens who intercepted these messages could understand the meaning. In August 2009, Australia's "National Science Week" launched an activity called "Greetings from the Earth" to send short messages to aliens. These short messages are converted into mathematical language and sent from Canberra Spatial Information Center to Gliese 581D. It is estimated that this information will not reach there until 2029. In August this year, the National Geographic Channel cooperated with Arecibo Observatory to compile the messages about aliens collected by netizens on Twitter into mathematical language information, and sent out the signal "Wow!" 35 years ago. (Wow! ) in the spatial direction.
