In the double slit experiment, it was found that the electron itself is both a particle and a wave.
When the researchers wanted to see from which slit the electron entered, the experimental result would be the state of "particle".
The weird thing was that when double-slit was not observed, the experimental result would be the state of "wave".
When there was no consciousness involved, there were still many possibilities for electrons to present the state of wave. While if electrons are perceived by consciousness, they would be shaped into state of particle.
The result of this experiment was that our consciousness can really change the reality. If humans’ consciousness can be united and treat all living creatures correctly, the mainstream values of the whole world would surely be changed.
