    I Determinism, realism, hidden variables

    I am thinking about using spots on a computer screen to simulate entanglement of particles in space. Could I do it or would it contradict Bells? It would have a button that when clicked then pairs of spots would reveal their correlated states (I would random number generator to set the color of...

    B Does quantum physics imply the existence of randomness?

    I thought a property could not have an infinitely precise value because infinity is never ending. Kinda obvious!

    I Determinism, realism, hidden variables

    I ask a question: could I write a program that simulates two pixels as entangled? The pixels themselves have no influence on each other. All the influence is done behind the scenes by simple code. Does that contradict Bells somehow?

    I Determinism, realism, hidden variables

    Think of entangled particles like two alternating flashing pixels on a screen. Neither pixel has any information about its position yet when one is red the other is green and vica-versa. They do not signal each other at all and have no knowledge of each other's state (color) yet their...

    I How "spooky action...." may work?

    Its the same problem as what hidden variable is contained in two particles that tells them that they have collided with each other. The particles contain no property like temperature, mass etc that gives them their location in space. So how do they know when they collide?

    B Does quantum physics imply the existence of randomness?

    The collapse of the wavefunction could not be *completely random* in practice because that would mean an exact point-position to an infinite number of decimal places.

    B What Is an elementary particle?

    It goes back early atomism - matter is made of particles that are indivisible. The key idea is *indivisibility* which persists through the ages to today. But today we term a particle as something that interacts and makes tracks in bubble chambers and forget about indivisibility.

    Can the following explain randomness in quantum events?

    Retro-causality yes. Then transitions then become 'steps' in 'zero time' - perfect!. We think of a quantum energy exchange between, say, atoms of hydrogen in a gas without considering the separation of the atoms. Why? Oh, because its 'too small' so let's neglect that awkward complication. We...

    New experimental proof of wave-function collapse?

    The wave function collapse is a value exchange - a numerical event!

    Is the electromagnetic field more or less real than the quantum wavefunction?

    But that means that the whole area of the wavefront needs to know instantly that it's been detected.

    Is the electromagnetic field more or less real than the quantum wavefunction?

    When a photon is at a large distance fom it's starting position then the wave is spread-out laterally. How can a wavefront for one photon collapse instantly over a massive surface area?

    Exactly how is causality violated by superluminal travel?

    Assume light travels a planks length in one clock tick - and also assume that this is ontologically how light (or information) travels in space-time. Then Lorentz corrections can be applied and all is dandy as we know already. Now, assume that in one click of the clock an entity can travel...

    Exactly how is causality violated by superluminal travel?

    OK. Right. I have this simpler scenario. Its very simple- I hope. Bob (the cause) kills Alice (the effect) with a laser beam that takes 10 minutes to arrive at her location. Alice's friend (Martha) sees the dead Alice and jumps into an FTL rocket to try to reverse the death. She travels...

    Interpretations of Quantum Mechanics (is there a general consensus?)

    So a wave function is not a wave and its not a particle, its an entity of some sort in 'superposition' that spreads out in x,y,z and t. We can only find out if its 'there' by decohering it. Otherwise it is not a physical, real entity. It behaves as though it were a 'calculation' waiting for...
