Classical physics is assumed to be both materialistic and objective.
Classical objects are assumed to have separate, independent existences whether or not they are being observed.
Classical objects are assumed to have definite properties, such as position, velocity, and orientation whether or not they are being observed. These properties are assumed to have no intrinsic uncertainties.
Classical objects are assumed to be acted upon by classical forces such as electromagnetism and gravity.
The laws of classical physics are deterministic. This means that the state of the universe in the future is assumed to be completely determined by the state of the universe at the present, which is assumed to be determined by the state of the universe in the past.
Remember: Objective reality is reality by agreement.
Collapse must occur over all space simultaneously because our observations must be consistent with our agreement on what exists or doesn’t exist.
For example, if you and I agree that there is one and only one electron, then you cannot observe the electron to be at one position while I simultaneously observe it at another. (This is the “agreement” property of objective reality.)
The agreement property leads to the requirement of nonlocal collapse.
Albert Einstein’s (1879-1955) invented the special theory of relativity in1905. Einstein made the following two assumptions:
1) The velocity of light in vacuum is a constant, independent of the relative velocity (also assumed to be constant) of two observers observing each other. This assumption was consistent with the measurements of Michelson and Morley (1881).
2) No physical effect, including information, can travel faster than the velocity of light. This was also consistent with the measurements of Michelson and Morley.
• This is now considered to be a physical law, more than just a theory, because it has been verified innumerable times both directly and indirectly. No experiment has ever invalidated it.
Remember: Nonlocality in the Copenhagen interpretation means that collapse happens over all space simultaneously. (This is required for simultaneous observations to be consistent with what is assumed to exist or not to exist).
But: Einstein’s special theory of relativity says that no physical effect can travel with a velocity greater than the velocity of light.
Thus: There is no known physical explanation for anything that happens over all space simultaneously, so there is no known physical mechanism for nonlocal collapse.
Thus: There is no known physical mechanism for the “agreement” property.
The idealist solution to nonlocality in the Copenhagen interpretation
In this solution, it is consciousness that collapses the wavefunction, not a physical process.
Because simultaneous observations made by separate observers must be consistent with our agreed-on reality, there can be only one consciousness.
Hence, this consciousness must be nonlocal and universal. This is required for the “agreement” property of objective reality.
Because, in the idealist interpretation, nonlocal universal consciousness is nonphysical, it can collapse the wavefunction over all space simultaneously, so nonlocality is preserved.
(This explanation for wavefunction collapse is not widely accepted but no physical explanation has yet been found.)
The many-worlds interpretation was proposed so that the entire universe could be described by a single wavefunction.
The wavefunction is assumed to exist as the only objective reality from the moment of the big bang.
Since there can be no observer or observation that is separate from the universe, the wavefunction never collapses.
At any moment that “I” (as part of the universe) make an observation, the wavefunction branches to manifest the world that “I” observe with a probability given by the wavefunction. There is no wavefunction collapse, but there is a manifestation of my world.
In this interpretation, there is assumed to be no objective reality. There are only subjective observations.
The wavefunction is assumed to be nothing but a mathematical algorithm used to calculate the probability that a particular observation will yield a particular result.
Since there is no objective reality, there is no space-time and no nonlocality.
Since there is no nonlocality, there is no problem of nonlocality.
Solipsism vs. nonsolipsism in the subjective interpretation
• In a solipsistic view, there is only one observer. (This view does not require agreement on what is being observed.)
• In a nonsolipsistic view there are at least two observers.
• In order for there to be communication between observers, this view requires agreement on the definition of what is observed. For example, we must agree on the definition of “chair” before we can talk about our observations of a chair.
This is the “agreement” property of the subjective interpretation.
Even in the subjective interpretation, if there is more than one observer, agreement is required!
In both the objective and subjective interpretations of quantum theory, there must be agreement—in the objective case, on the definition of what exists or does not exist, and in the subjective case, on the definition of what is observed or what is not observed.
But, agreement requires communication, and communication requires agreement.
Therefore, is it possible that the need to communicate is our most basic need, even more basic than the need to survive?
Is it the heart that needs to communicate, or is it the mind?
Is the need to communicate a reflection of our innate connectedness?
In objective time (time as measured by a clock or other instrument), any neurological or sensory process always happens before our awareness of it because the brain requires a few tenths of a second to process an event before we are aware of it.
Thus, all subjective experiences happen after the corresponding objective events. This applies to “volitional” experiences as well as “nonvolitional” ones.
Mantra practice helps us to get out of our heads and into our bodies. It helps to heal the separation between the mind and the body. All mantra practice is to be done audibly and mindfully in such a way that the mantra resonates throughout the body.
