Quantum mechanics has not been accepted by all physicists, even though scientists at the school in Copenhagen have been added more and more. An important example of a scientist is Einstein who, together with Podolskj and Rosen, enunciated the following paradox: “If the laws of quantum physics are true, we can deduce that two particles that are in resonance with each other because they are the fragments of a single particle that has split and whose two fragments have moved away from each other, then, if I do something about one of the two particles, instantly even the other feels its effect; but this violates the principle of causality and this can not therefore be, from this conclusion we can deduce that quantum physics can not be true.”
In short, Einstein – and with him a minority of physicists of the last century – was afraid to overcome the concept of cause and effect (what Prof. Vitiello calls “ontological prejudice”).
In reality, Bohr and all the physicists defending quantum mechanics have always responded by claiming that the experimental results confirmed the theory without going any further. They too did not dare to overcome the concept of cause and effect.
Finally in 1964 John Stewart Bell enunciates this theorem which is a stupendous masterpiece of logic:
“The following set of 3 statements is logically incompatible so that one of the following 3 statements must necessarily fall:
1) physical reality is described by quantum physics
2) physical reality is susceptible to objective description (ie independent of the observer)
3) physical reality is describable as a set of events located in space and time”
Einstein and company preferred to reject the statement n. 1).
Bohr and company did not want to renounce the space-temporality and have made the n. 2) claiming that the observer influences the experiment by making him lose objectivity (Eisemberg’s uncertainty principle).
For example, the phenomenon of superconduction is an exclusively quantum effect.
The largest superconducting cable in the world, installed on a north-south axis in the LIPA infrastructure in Holbrook, USA, can transport 574 MVA at full load, sufficient to supply electricity to 300,000 apartments !! The size of this cable is such that it no longer allows us to claim that the particles involved in the experiment are so small that the experiments are influenced by the laboratory. What to answer Bell in cases like these?
Finally in this century (to go by Boehm) physicists make the n. 3) paving the way for the synchronization of events at a distance and the overcoming of space-temporality !!! A real Copernican revolution that overcomes the ontological prejudice !!!!
This is a huge achievement. In fact, with the fall of this prejudice, the road to physics opens up to concepts such as bilocation, synchronization of events at a distance (thus exceeding the speed limit of light), etc.
