Bohm (faster than light reactivty?)

[TRUGONOWFOR]

Can someone please tell me what exactly the Bohm experiment was in which he seemed to show that (and I am not exactly sure of this) that a segment of a particle (call it particle split "A") split from another particle segment (Call it particle split "B") could result in particle split A causing in a reaction to particle split "B" in less time than it would take for light to travel from particle A to Particle B? If someone could explain what happened during this experiment (and maybe even how it was that a person could measure that a faster than speed of light transmission of reactivity has occurred) I would greatly appreciate it. Does Bohm prove that faster than light activity is a reality or what exactly was the experiment and what did the results suggest?

The Bohm experiment, also known as the Aharonov-Bohm effect, is a thought experiment proposed by David Bohm and Yakir Aharonov in 1959. It involves a hypothetical scenario where a particle is split into two segments, A and B, and then recombined. The experiment was designed to test the idea of quantum nonlocality, which suggests that particles can have instantaneous interactions with each other regardless of distance.

In the Bohm experiment, the particle segments A and B are placed in separate regions, with a magnetic field present in the space between them. The magnetic field is designed to be strong enough to alter the path of the particles, causing them to move in a circular motion. The magnetic field is then turned off, and the particles are allowed to pass through a device that measures their path.

According to classical physics, the particles should not be affected by the magnetic field as they are not within its range. However, in quantum mechanics, the particles are described by wave functions, which can overlap and interact even when physically separated. This means that the particles can still be influenced by the magnetic field, even though they are not in its immediate vicinity.

The results of the experiment showed that the particles did indeed exhibit interference patterns, suggesting that they had been affected by the magnetic field. This interference pattern could only be explained by the particles having some kind of nonlocal interaction, as predicted by quantum mechanics.

However, it is important to note that this experiment does not prove that particles can travel faster than the speed of light. The particles themselves are not actually moving faster than light, but rather their wave functions are interacting in a nonlocal manner. This does not violate the principle of causality, which states that an effect cannot occur before its cause.

In conclusion, the Bohm experiment provides strong evidence for the idea of quantum nonlocality, but it does not prove the existence of faster-than-light communication. It remains a fascinating and thought-provoking concept in the world of quantum mechanics.
