Actually, it doesn't interfere with itself when you look at some other
electron that hasn't gone through the apparatus at all. In other words,
looking at some other entangled electron controls whether *this*
electron interferes with itself.

Now, explain how you get the photon going thru one slit or both slits,
based on some other photon at a spacelike distance away from the other
equipment?

"As if" is the operant term here.

But not if you look at some other entangled photon and measure something
irrelevant?

Weren't you, btw, the one arguing that not having a competing theory for
evolution wasn't sufficient to dismiss evidence-free arguments against
theory of evolution?
