If a tree falls down in the forest and no one is around to see it does it really happen? What do you think?
According to one quantum physics theory, a particle’s behavior changes depending on whether we are watching or not. This meaning that reality is an illusion and only exists when we are looking at it. Tons of experiments have been done on this and it seems very possible.
More information is constantly coming about for instance when physicists at the Australian National University recreated the John Wheeler’s delayed-choice experiment and seem to have confirmed that reality really doesn’t exist until it is measured. The results of their experiment were published in the journal Nature Physics and it shows that at least on a quantum level reality does not exist unless you are looking at it. This is just one of many big steps when it comes to quantum theory.
Using helium atoms scattered by laser lights these smart individuals were able to recreate a more conclusive version of John Wheeler’s experiment from the 1970s. The atoms in this were either acting as a particle and pass through one arm or acting as waves and passing through both arms. Multiple gratings were added randomly to recombine the paths and as a result, they found the second one caused interference in the measurements. This showed that the atom had traveled both paths and those that didn’t only one.
For more on this experiment please take the time to watch the video below. This experiment is just one of many that are adding to the validity of the quantum theory. We are uncovering new evidence every single day and are well on our way to uncovering something huge. Is this enough thought provoking for today?
