Hi guys, I have a wavefunction collapse question that does not involve entanglement:
Suppose I have a set up containing one electron. 8 light minutes away I placed a detector B that can read the spin of the electron (and can flash red if spin up, green in spin down).
Suppose I have a friend Ann standing next to detector B.
Now I use another detector A next to the electron unit to measure my electron spin. Suppose my measurement collapse it to spin up. will I expect 8 minutes later, Ann will inform me her detector flashes red?
