The concept of "degrees of separation" suggests that we are connected to every person in the world through a chain of relationships. It suggests that we are only one degree away from people we know directly, two degrees away from friends of friends, and so on.
It emphasizes that the world is a small place, and our networks can expand and connect us to people we may not know personally. Although it assumes no barriers or limitations to the flow of information or relationships, cultural, geographical, and other factors can affect the actual degrees of separation between individuals. Nonetheless, it provides a useful framework for understanding social connections and networks.
