THANK GOD. I was almost beginning to think consciousness had some effect on matter. Now I can rest safe knowing I’m still a powerless blob of meat with tons of debt fighting against the inexorable increase of entropy. I love science!

I think you missed the whole 'if you measure which hole the particle goes through your measurement of the particle defines if the particle acts as a single hole wave function or a double hole wave function,' you're still affecting things but you're not affecting them backwards in time only their future position

I watched a couple of videos on the double slit experiment some time ago and the videos never mentioned consciousness being able to affect the past. Needless to say the videos were meant for lamemen such as myself, but still.

the difference between double slit and delayed choice eraser is that delayed choice, there is a set of paired photons, A is observed earlier than the other, and will display the effect of a wave or particle depending on which sensor B enters. If B enters a sensor that tells us which slit it passed through, a two bar pattern is shown in the earlier detector and the later detector. If B enters a sensor that does not tell us which slit it passed through, it gives the wave pattern on both the early sensor and later sensor. 

double slit is used as the basis for this experiment, this is an extension of the double slit.
