BUTTERFLY EFFECT MORE THAN JUST THEORY
In Chaos Theory, the butterfly effect is the name given to the sensitive connection between initial conditions in which an insignificant event in one state in non-linear systems, can result in sometimes catastrophic events in the universal state. In other words, in theory, it is possible for a butterfly flapping its wings in Texas to cause a typhoon in the Japanese Sea.
Case in point, in mid-20th Century America, a loose 18-year-old hippie female in a Honolulu college had sex with an older, alcoholic Kenyan man on a student visa, who had a wife and child back in Africa. And this less than significant event started the collapse and dissolution of the United States of America in the 21st Century.
