- Does observing a particle cause it to exhibit a certain quality? What is the cause and effect relationship involved with observation?
In the double-slit experiment when a detector was placed before the two slits, a 2 strip pattern was produced after the two slits. When there was no detector placed before the two slits, a different pattern was produced after the two slits. Why does the presence of a detector before the two slits cause a different pattern to be produced after the two slits?
