Every now and again, I sit and try to explain my views on physics and reality to someone who is not really interested (a fresh mind) but will ask questions.
The latest effort raised this crucial point.
In the double slit experiment, Prof Cox and many others believe that a photon can be anywhere in the universe, perhaps at the same time, and that the photon may travel via a distant galaxy to the screen where it is eventually seen.
I was asked when running through this horrendous paradox:
How do they know the electron goes via another Galaxy. If the speed of light is a limit that would take millions of years to make the trip? They don't wait that long.
Have they timed any of the photons taking more than the expected time to reach the screen? If anything is possible there should be some.
If they can travel that far that fast, surely some should get there quicker than expected?
When they fired them individually, did any go missing?
What bloody superb questions....
I said a standard answer is that although all those are possible, they are so improbable that we would have to experiment for a looooong time to see them.
response: Sounds bo**ocks to me. sounds more like there a rules and nobodies really seen them broken, so we simply don't understand the rules yet.
.... I had to agree
