Roger Penrose thinks Quantum is wrong on Probability Wave Collapse


Delving into the foundations of quantum mechanics and the measurement problem.

_The Wave Function:_

In quantum mechanics, particles are described by a wave function (ψ), encoding probabilities of finding the particle in various states.

_The Measurement Problem:_

When measuring a particle's state, the wave function "collapses" to one definite outcome. This raises questions:

1. What causes wave function collapse?

2. How does the measurement process select one outcome?

_Sir Roger Penrose's Concerns:_

Penrose, a renowned physicist and mathematician, argues:

1. If particles are fundamentally uncertain (wave-like), what triggers collapse?

2. How can a measurement, itself a physical process, induce collapse?

_Orchestrated Objective Reduction (Orch-OR) Theory:_

Penrose proposes Orch-OR, suggesting:

1. Wave function collapse is objective, not subjective (i.e., not due to observation).

2. Collapse is triggered by quantum gravitational effects, linking to the fundamental nature of spacetime.

_Penrose's Critique of Standard Quantum Mechanics:_

1. Quantum mechanics relies on an unexplained, non-physical "measurement" process.

2. Wave function collapse seems arbitrary, lacking a clear physical mechanism.

_Alternative Perspectives:_

1. *Copenhagen Interpretation*: Wave function collapse is a fundamental aspect of measurement.

2. *Many-Worlds Interpretation*: Wave function never collapses; instead, universes branch.

3. *Pilot-Wave Theory (Bohmian Mechanics)*: Wave function guides particles, no collapse needed.

_Quantum Foundations Research:_

Ongoing efforts aim to:

1. Resolve the measurement problem.

2. Understand wave function collapse.

3. Develop more complete quantum theories.

Some notable research directions:

1. *Quantum Gravity*: Merging quantum mechanics and general relativity.

2. *Quantum Information Theory*: Studying quantum systems' information processing.

3. *Experimental Searches*: Investigating wave function collapse and quantum non-locality.

Penrose's concerns highlight the need for a deeper understanding of quantum mechanics and its foundational principles.

1. Explore Orch-OR theory in more detail?

2. Discuss the implications of quantum gravity on wave function collapse?

3. Investigate experimental approaches to studying wave function collapse?

Albert Einstein's views on the measurement problem and wave function collapse:

_Einstein's Concerns:_

1. *Reality vs. Probability*: Einstein believed quantum mechanics only provides probabilities, not definite realities.

2. *Wave Function Collapse*: Einstein questioned the arbitrary nature of wave function collapse.

3. *Non-Locality*: Einstein was troubled by quantum entanglement's implications on spacetime.

_Einstein's Quotes:_

1. "God does not play dice with the universe." (objection to probabilistic nature)

2. "Do you really believe the moon is not there when nobody looks at it?" (questioning wave function collapse)

3. "Spooky action at a distance" (critique of quantum entanglement)

_Einstein's Position:_

1. *Realism*: Einstein advocated for a realistic interpretation, where physical properties exist independently of measurement.

2. *Determinism*: Einstein believed physical laws should determine outcomes, not probabilities.

3. *Locality*: Einstein supported locality, rejecting non-local influences.

_Einstein-Bohr Debate:_

Einstein's views clashed with Niels Bohr's Copenhagen interpretation. Their debate highlighted fundamental differences:

1. *Einstein's EPR Paradox* (1935): Einstein, Podolsky, and Rosen proposed a thought experiment challenging quantum mechanics.

2. *Bohr's Response*: Bohr argued quantum mechanics is consistent, but Einstein's concerns remained.

_Penrose's Alignment with Einstein:_

Sir Roger Penrose shares Einstein's concerns, advocating for:

1. *Objective Reality*: Penrose supports an objective, realistic interpretation.

2. *Deterministic Physics*: Penrose seeks a more fundamental, deterministic theory.

3. *Critique of Non-Locality*: Penrose questions quantum non-locality's implications.


By aligning with Einstein's views, Penrose continues the quest for a more complete understanding of quantum mechanics.

1. Explore Einstein's EPR paradox in more detail?

2. Discuss Bohr's response and the Copenhagen interpretation?

3. Investigate Penrose's Orch-OR theory as an alternative?

Physics: What actually is time? Why doesnt it go backwards? Decay Theory tries to answer

Image
Stephen Hawkings  said the universe is nothing but a collection of emergent fields, states and systems. Nikolai Tesla said the universe is vibrations and frequencies.  To agree with the two I consider time as a rate. So everything bubbles out and dies or gets replaced. You are made of mass which is made of discrete units that bubble out and die down being replaced by other units . The rate of emergence, de emergence and discrete causal frequencies. I believe time emerges and de emerges just as any quantum system. Quantum systems bubble out, obey probability, take logic states before de emerging or decay out to  lower states. So if emergence represents causality or the disruption of equillibriun, then time is the rate frequency of that process. I refer to causality and effects. I also refer to Nikolai Tesla:  "If you want to understand the universe, think about frequency rate and vibrations." Loop Quantum Gravity considers the universe as made of granules of space tim...

Why Time doesnot go backwards: Short answer

Image
The Decay Theory Cosmology developed in Africa in 2024 by an independent scholar Harry Mangulenje as a proposal into Quantum mechanics, posits that TIME can be conceptualized as a quantifiable rate of decay, wherein systems exhibit entropic progression from higher to lower energy states.  This theoretical model, developed by Harry Mangulenje, integrates principles from quantum mechanics and thermodynamics to elucidate the fundamental nature of time and the universe. The theory proposes that the universe operates within a fluid dynamic of discrete quanta states, emerging and demerging spontaneously under probabilistic guidance.  As these systems evolve, they undergo decay from higher to lower states, ultimately attaining a logical state that represents the lower profile of their probabilistic nature. This perspective implies that time serves as a measure of the rate of this procession, quantifying the progression from emergence to de emergence or decay or collapse. The irrevers...

The real origin of the universe

Image
The origin of existence can be attributed to the spontaneous breakdown or decay of a nonentity equilibrium also can be termed as quantum vacuum. If you like, this can answer the question, what existed before the university in the very initial state of absolute emptiness. The state of absolute emptiness or absolute quantum vacuum was a state of probabilistic equilibrium where every possibility was nullified by equal and opposite, for example we can be sure that possible entities were nullified by anti entities resulting in probabilistic equilibrium. But spontaneously this condition failed by itself leading to a breakdown of the equilibrium. When equilibrium collapsed or decayed energy entities got manifestation and evolution begun. So time could be traced way back to the breakdown of equilibrium when entities began to evolve. This triggered the emergence of existence and its fabric, including time.  Quantum vacuum equilibrium or nonentity equilibrium is where all probabilistic ener...
