There may be times when we feel like our connection to the universe is closed.Maybe things don't seem to be going well in our day，or our lives，or we may feel out of our element.The truth is，the universe is always there for us.We know that we create our experience with our thoughts，and this is another way we need to make a conscious decision about how we want to experience life.It is up to us to do the work of making the connection，because nobody can do it for us，though sometimes the universe may send us wake­up calls.

Each year Ben is glad when school is closed on Martin Luther King Jr.Day.Ben knows that this day honors an important man，but Ben does not feel connected to him.However，the small­world theory connects Ben to Dr.King.Ben's mom (0) has a close friend，Amy (1)．Amy's uncle，Mark (2)，once met and spoke to John Carter (3)，the son of President Jimmy Carter (4)．Jimmy Carter knew Dr.King (5)．In a way，Ben is only “five people away” from Martin Luther King Jr.

The small­world theory says that everyone in the world is connected through a short chain (链条) of people they know.Another name of this chain is degrees of separation.Each degree is a step that separates a person from someone he or she does not know.There are zero degrees of separation between a person and the people he or she knows directly.This means that there are zero degrees between Ben and his mom.There is one degree of separation when just one person separates someone from a person he or she does not know.The theory says that there are no more than six degrees of separation between any two people in the world.
