| Sep 6 at 5:48 | comment | added | James | @RogerV. ... might it be possible to force a grandfather paradox type of situation involving collapse? Suppose a granddaughter reflected wave is used to force trigger a measurement of the polarization of the original grandfather wavepacket. Then collapse to due measurement may result in this granddaughter wave not existing in the first place, but this means the measurement will not have been triggered which revised the history in the first place, etc. | |

At the moment of measurement, it had to collapse not just the wavepacket but also some surrounding fields to ensure consistent history, right? Since $E$ and $B$ have very strict time evolution rules, does this entail revising/collapsing the entire field everywhere just to satisfy this wavepacket's newfound identity? | |
