Wheeler’s Delayed Choice Experiment
Explore one of the strangest ideas in quantum physics, where the way a particle is measured appears to affect how it behaved in the past. These posts look at light, photons, waves, particles, observation, probability, and John Wheeler’s challenge to ordinary ideas of cause and effect. They also consider what the experiment may suggest about time, reality, and whether the universe has definite properties before it is measured.
Quantum
Does our reality exist if we are not observing it? Can time travel backward? These seemingly absurd questions derive from two incredible experiments that beg such questions. The first experiment is
