Six Degrees of Separation TheoryPlease elaborate on the Six Degrees of Separation Theory?

The Six Degrees of Separation theory is also known as the Six Degrees of Separation theory. This theory can be loosely summarized as follows: "There are no more than six people between you and any stranger, which means that you can recognize any stranger through a maximum of six people." The theory was developed in the 1960s by the American psychologist Milgram. "Six degrees of separation" describes the prevalence of "weak links" in society, but they play a very powerful role. For human society, through the network, the theory of "six degrees of separation" can constitute a weak link for everyone. The "weak ties" that are prevalent in society make people very "close" to each other, and this plays a huge role in social relations. Rough Proof of Six Degrees of Separation Assuming that a person can know more than 25 people, after seven introductions (six people apart) a person can be introduced to 25 to the seventh power of 25, which equals to 610,351,5625 people, more than 6 billion! And 25 is just a conservative number, so in fact the result would be much larger, definitely exceeding the population of the earth 1. Microsoft researchers have recently experimented with the Six Degrees of Separation Theory using information from the Internet. The results were shocking. According to researcher Eric Horvitz, the exact term is "6.6 Degrees of Space Theory". In other words, you can recognize any stranger through up to 6.6 people. 2. 2. The researchers studied the addresses of 30 billion instant messages sent through Microsoft's instant messenger MSN in one month in 2006. They calculated that 78% of the people who sent messages could be connected through 6.6 messages. The Microsoft study also showed that this result does not change with population growth or advances in communications technology. 3. Horwitz said: "This result suggests that there may be ongoing social connectivity among humans. We have demonstrated experimentally that the six-degree theory is not folklore." 4. This theory was first proposed in 1929 by the Hungarian writer Fritzis Karinth in a short story. In it, he states that all the people in the world can be connected by up to five intermediaries. 5. In 1967, Harvard social psychologist Milgram devised a chain letter experiment. He sent letters to 160 random people in Nebraska containing the name of a Boston stockbroker, and asked the recipients to send the letters to friends they thought were close to the stockbroker. Eventually, most of the letters reached the stockbroker after five or six steps. Since then, the theory of six degrees of separation has received worldwide attention
