- Does Richard Feynman's multiple histories ignore alternative histories?
Summary: Does Richard Feynman's multiple histories ignore alternative histories?
Did Richard Feynman's multiple histories (https://en.wikipedia.org/wiki/Multiple_histories) ignore the existence of other alternarive histories or paths?
I ask this referring to this comment from this page: http://sciencechatforum.com/viewtopic.php?f=46&t=16239
"The Feynman path integral assumes that only where you don't observe it the particle could be trying all different ways to get from A to B. If it INTERACTS with anything along the way, like a detector or a barrier with slits to pass thru or just another particle then where it went is NAILED DOWN. The alternatives do not exist --- the path integral formula ignores them"
But is this completely right? Are alternative histories completely eliminated in Feynman's sum up over histories?
