'Spooky' quantum experiment: measurement of a photon affects its location

The article is not clear. Even the linked article is not clear.

How is that different from the particle view ? Either the particle goes to A or it goes to B. Saying that it goes to both but then when you measure A it collapses in either A or B is the same thing. No ?

Particles pretty much _need_ to be in a few places at once, even for such simple things as establishing chemical bonds:

And the difference between being in two (or many) places at once, vs just not knowing where it is, results in different energies.

Flash flash flash. Einstein was wrong wrong wrong!
