When you have the delayed choice quantum eraser, and you make it really really big and you put a measuring device just before the prism where the entangled photon will hit (Kim et al experiment). Does that mean that when that measuring device is 1 light year away and the people operating it can change whether or not it is turned on or of. They can decide the past? By turning the device on (and keep it on) they know that a year earlier people did not see an interference pattern?
