Does reality really exist? Does a tree that falls in the middle of the forest make a sound, if there is no one who can hear it? Is it possible to change, modify, replace or create a new reality?

Quantum theory was a true revolution in the act of turning around what it had been understood in terms of the concept of reality. Suddenly concepts began to be used that until then only had dared to present the so-called mystics and magicians who, in spite of themselves, had seen how his beliefs had been taken, at best as articles of joke.
Science began to use concepts such as “the act of observing modifies the observer's perspective ”. Reality itself ceases to exist as something objective.  It exists because we believe it. We change our beliefs and our reality changes.
It can be said that matter behaves according to what we want to see and the world can be modified by our observation.
David Bohm, an expert on quantum theory, Einsteir's colleague at Princenton, reformulated the way of understanding the quantum nature of the world, with a view to addressing a greater phenomenological reality, the psyche, which tries to explain in its last research.
He is the author of the hidden variables theory, formulated in 1952. After his encounter, with the Eastern philosopher Jiddu Krisnamurti, he began to wonder about the scientific explanation of consciousness.
From his theories the following can be seen: “The instantaneous communication of subatomic particles under certain conditions, regardless of whether distances that separate them are ten meters or ten billion kilometres; It is not because there is a speed greater than that of light, but because actually there is only one particle and that the separation is actually an illusion. Thus according to his reasoning, all the images of the universe would be formed by the illusion of separate particles that is not real, concluding that everything we see does not exist, it would be just an illusion, the only real thing is the observer while the observed is an illusion. We enter the world of Maya.

The brain is not able to distinguish between what happens inside it and what that happens outside. This concept in itself opens us to an immense field of possibilities. If you see what you believe in, if you believe something, it will come true.
