Italics mine: "If I measure one electron in my lab, the second electron is affected by the measurement of the first electron with no time delay—instantaneously

Italics mine:
"If I measure one electron in my lab, the second electron is affected by the measurement of the first electron with no time delay—instantaneously— even though a signal travelling at the speed of light would take millenia to cross the distance between them."
Yes, from our reference frame it takes millennia, but from a photon's reference frame (if that notion has any meaning) it is in fact instantaneous. Is this just a weird coincidence? I'm not sure how to even phrase it but is there some "quantum perspective" where the wave function collapse is synonymous with the speed of light reference frame?

- plonh 11y agoRelatively is not fully compatible with quantum mechanics. This is the largest open problem in fundamental physics.
- xefer 11y agoSure but I'm just trying to making a general observation and making note of the curious symmetry. It's interesting that an electron dropping to a lower energy state could be, in some sense, effectively connected to another electron millions of light years away via a photon whose reference frame would have no time pass or distance travelled. Those two electrons are in a weird way as connected from the photon's perspective as two entangled electrons are from our perspective.
- deepnet 11y agoAn interesting idea, but photons are limited to the speed of light, instantaneous is much faster.
