A Note On The Butterfly Effect

In my previous post, I mentioned the Butterfly Effect: a butterfly flapping his wings in Gondwanaland 100 million years ago changes the time lines for the future...or one doing so in Alaska affects the weather in New York...small things have big consequences.

It isn't all that prevalent in the physical world. The butterfly wing flapping is totally overwhelmed and drowned out by the tidal wave of events surrounding it.
That boldly flapping butterfly will have no effect.

How do I know this?
I call it the Darwin-Wallace Effect: both Charles Darwin and Alfred Wallace had come up with their ideas on Evolution at the same time; long story short, there are so many events being generated at any time, there is redundancy, doubled, tripled, maybe to the 100th power.

If we go back in time and kill an ancestor, will we be born?
Yes. In effect, yes you will be.
There is redundancy. We've noticed it forever, how ideas and inventions are synchronistic. Jung's idea of synchronism maybe just another word for redundancy - back up systems that take over when some moron goes back in time and kills his da.
The threshhold at which the time line may truly be altered requires impossible activity; we cannot achieve it. The Time-Altering-Threshhold is a physical constant which may never be breached, because the computation required to achieve it, erase the previous time-line,  and evolve its altered  time-line,  surpasses all available computational ability, past and future.
( I mean, if we could do it, it would like seriously sloooowwww things down - like waiting for a large bitmap to download during hours of heaviest internet use; serious slow down. That would be that world where light has a speed of 55 miles per hour.)
