What's that myth about a butterfly flapping its' wing and a tsunami happening?

I know there's a myth or theory about it, like a butterfly flapping its' wing in New York and a tsunami happening in Florida? Something like that.|||It's not exactly related to time travel. Th point is, small things in a seemly ordinary place or time can lead to exponential events. It's an exercise proposed into the chaos theory that the small turbulence from a butterfly flight can lead to a chain event so massive that it could produce a hurricane some time after. This is used in meteorology to find non linear patterns for better weather predictions, for being a non linear system, the weather is a chaotic System. Also, keep in mind that it's really unlikely that a butterfly flap actually leads to a hurricane, it's just and example, and NEVER to a tsunami, tsunamis and hurricanes are completely different things. Tsunamis originate with earthquakes on the sea floor, and there's simply nothing that living beings can make on the surface of the planet that is big enough to cause this kind of earthquake.|||It's to do with chaos theory.

Scientists love to come out with memorable notions which then often get tragically misunderstood. The idea is that weather being an immensely complex and unpredictable system is highly sensitive to tiny influences.





So maybe a butterfly flaps its wings and later on the tiny air currents get bigger and bigger and end up causing a hurricane while if the butterfly hadn't flapped its wings then maybe a hurricane wouldn't have formed - or at least would have formed in a different place.





If you want a source on chaos theory suitable for a layman I'd recommend 'Chaos' by James Gleick.|||I believe it's a theory (not a myth) about changes in time. A small cause far enough in the past can cause enormous consequences in the future. A butterfly flaps its wings, and the weather gets affected by the wind to an extent that a storm hits on the other side of the world.|||it's called the Butterfly Effect.


I was able to locate some information on Wiki


http://en.wikipedia.org/wiki/Butterfly_e鈥?/a>|||Assuming you can time travel to the past, an insignificant change in events (butterfly wing flap) could lead enormous changes (tsunami) in the future.|||Its just a philosophical metaphor referring to everything happening for a reason.|||whatever...........


no one can change the past and predict the future anyways.
