Here is my proposed,  non-mystical explanation of the double slit experiment and its variants, the delayed choice and the quantum eraser.

Given that light behaves as a wave when there is a choice of which slit it goes through and as a particle if the choice has been made. This is what we observe so far. In the first case, there is an interference pattern, and in the second case not.

From the photon's perspective, Special Relativity says that its clock is stopped. In other words, time does not matter and it takes zero time for it to go anywhere.  The choice of wave or particle is made instantly. There is no paradox for the photon.

However, from the viewpoint of observers in the lab who are not moving at the speed of light, time of flight is greater than zero. There seems to be time to make a choice. But this is an illusion because the choice was made when the photon began its trip. Choice cannot be realized because the photon wave function dictates the outcome in advance no matter how much time is involved. This explains all the seemingly impossible results of double slit, delayed choice, and eraser experiments.

This could be proven with double slit experiments involving particles that move slower than the speed of light - the slower the better. In this case, there would be time for a choice because the particle experiences time too. Then the delayed choice and quantum eraser would briefly show the actual effect of the interference pattern being erased or vice versa.

Muons raining down from space provide another real world effect involving Special Relativity. Muons are produced by cosmic rays in the upper atmosphere. They should not reach the earth because their lifetimes are too short. But they do reach the earth because their velocities are very high, making their internal clocks very slow. So they live long enough to hit the earth.

Thanks to my son, VAL, for some of the driving questions and suggestions imbedded in this post. Key was his idea, "In 3d computer graphics terms, it's like immediately calculating the path and destination of a projectile."
