I can't explain it but I can raise a confound: with the detector on, there will be a small electromagnetic field that it uses to detect the atoms (this based on his description of unplugging the detector) which will also have an effect on the atoms.

Turning off the detector will change the electromagnetic field of the detector and thus change its effect on the experiment.

Now, I am certain sure that they have thought of this and have an explaination that basically states this is NOT the reason for the difference.

Agreed. The particle is in a superposition of anywhere within the boundaries of probabilities around a central area. Only when looked at does the particle position itself in one point.

Which means that all our own future possibilities exist at the same time. Only when we arrive at one of those future possibilities, based on past events and experiences, do all those other probabilities collapse into what we experience.

I'm just guessing here, of course, of what the results of the double slit experiment COULD mean in our General Relativity world.

It's also possible that the "sphere of probabilities" and the "collapse of that function into one point when observed" within the tiny scale of Quantum Mechanics do not translate in the huge scale of General Relativity.

But it's all good and interesting findings.

That we live in a matrix, nothing what it seems, if I take my eyes off my reflection in the mirror .... I cease to exist. Everything and everyone are interconnected, at times we don’t realize that any and all of our actions create counteractions without any outward intent.
