Recent experiments have tried to identify which of the two slits a particle is coming out of on its way to the detection screen.

Light came to be understood as swarms of photons that individually hit the detection screen.

Equivalently, we can work in two simply connected regions with cuts that pass from the tube towards or away from the detection screen.

Already detection screens showed battle cruisers descending into the lower atmosphere.

The electrons will contact the spherical detection screen in a widely dispersed manner.

Experiments observe nothing whatsoever between the time of emission of the particle and its arrival at the detection screen.

Of the man-ships they saw only glimmers flicking across detection screens.

At that point a detection screen could either be raised or lowered.

If, on the other hand, the detection screen were to be removed, then:

Suppose that experimenters project the images onto two separate detection screens.
