Everyone knows about the placebo effect; the brain has some control over the physiology which is not very surprising. But even if this does not make much sense, if you intake a substance without any effect on human physiology, confusing the brain that this substance has a positive effect, the positive effect happens ("The lazy brain need be deceived, he could do without the substance).
But even though many are not surprised that the brain has control over physiology, or on the body A very old research had already shown that the brain also has control over the matter, and that the properties of matter change when observed. New evidence also shows this phenomenon.
So Double-slit experiment (aka Young's experiment) showed that the behavior of the particles changed depending on whether or not these were observed for a human being (I do not know if animals was used as observers in any research).
If the particles behave as determined by the brain, then the universe behaves as it determines the brain?
The universe and matter is something created by the brain?
There is something like the placebo effect but applied to reality and the universe?
