Quantum Double Slit Experiment

Slide 2

The mere act of observation can completely change the outcome of an event! When a camera observed the electrons, they acted as particles. However, when the no equipment was used to observe the electrons, they acted as waves and particles simultaneously.Then in 2002, a group of researchers set up the experiment in a way that the electron could not possibly receive information about the existence of an observing instrument. The setup was on a much smaller scale: a single photon was emitted and an interferometer that observed the wave-or-particle behavior was either inserted or not inserted. Here’s the kicker: The insertion of the interferometer took only 40 nanoseconds (ns) while it would take 160 ns  for the information about the configuration to travel from the interferometer to reach the photon before it entered the slits. This means in order for the photon to “know” if it was being watched, that information would have to travel at 4 times the speed of light, which is impossible(the speed of light is the universal speed limit). The Results: The photons acted like particles 93% of the time that they were observed. Even if the photon “guessed” the configuration each time, statistically speaking it would never have more than 52% accuracy. In scientific experiments, a 93% success rate is as conclusive as they come.http://highexistence.com/this-will-mindfuck-you-the-double-slit-experiment/
