In 1978, there was an experiment called John Wheeler’s Delayed Choice Thought Experiment, Now after 40 years, Australian scientists have recreated this experiment by using helium atoms scattered by laser night. Consequently, they have confirmed quantum physics bizarre predictions about the nature of reality. They have shown that reality does not actually exist until we measure it.

This experiment shows how what happens in the present can change the way that things happen in the past. It shows how time can go backwards, how cause and effect can be reversed, and how the future caused the past.
