Are the Many Worlds interpretation and the Copenhagen interpretation falsifiable?

All interpretations of QM are called interpretations and not independent theories because they are not experimentally distinguishable.

Interpretations of Quantum Mechanics are not considered part of Quantum Mechanics, and arent even fucking science.

If you are ever smart enough to learn QM, interpretations will not be discussed (not even in a grad level).

Lookup reversible quantum computing. If you implement your consciousness as an algorithm and run it on a reversible quantum computer, have that copy of you make QM measurements, and then reverse the copy to its original state, the outcomes predicted by Copenhagen and Many Worlds differ.

In Copenhagen, an observation by a consciousness observer collapses the wavefunction and cannot be reversed. In Many Worlds, everything is a wavefunction, even conscious observers, so if the effects of the observation are canceled when the observer wavefunction is reverted.

You sound as dumb as a christian pal.

If the validity (or lack thereof) of an interpretaion of quantum mechanics has no correlation or consequence to the actual universe, it is akin to nonsense. It is a waste of time. It is like you discussing living in the MATRIX.

The sad part is that instead of actually learning quantum mechanics (actual science, actual verified predictions, actual verified explanations), people concern themselves with interpretaions (not science, doesnt make predictions, doesn't provide explanations that can be verified). They basically waste there time on philisophical nonsense, under the allusion that are learning actual science.

FYI: they are not falisifiable, meaning they are not science.

It is not possible to devise an experiment in Quantum Mechanics to prove or disprove any of the interpretations we use today. This is because as far as the science and math goes, they are all exactly the same. All interpretaions are exactly the same from an experimentalists perspective.

It may be possible to figure out the validity of an interpertation one day (far in the future), be it won't be done using Quantum Mechanics. It will require some more fundemental form of physics (that has not been invented yet). Good luck with that one....lol.

Copenhagen interpretation says that the wavefunction is inherently probabilistic, and it collapses to a singular value at some point, like when it interacts with something complex enough to be "classical".

On a side note, I tended to support Bohmian mechanics, until I came upon this counter-argument by Gary Drescher. Since the pilot wave is postulated to be real and mathematically equal to the Schroedinger wavefunction, then it doesn't matter whether there actually exist any particles guided by the wave.

>The wave itself is capable of computation and therefore supports conscious observers.

The point of view of the observer described by the Bohmian particles is just one of many points of view contained within this physical system. The particles themselves are redundant, and unnecessary by the law of parsimony. The points of view of all the other observers are consistent with many-worlds.

Nothing does. That's the problem with Copenhagen. The main thing that makes you treat something as a classical component is if it's you're measuring device. Copenhagen says the wave collapses there. Another interpretation (which predictably makes /sci/ rage) is that the wave collapses at consciousness. Many worlds / many minds interpretation says it never collapses ever.

My main beef with Bohmian mechanics is that it requires a preferred rest frame. And removing the particles that the wave guides around does not restore Lorentz symmetry. That's because the Schrodinger-picture wavefunction, which you're still considering to be a real object, is a function of a global time parameter.

Now what you can do to restore Lorentz symmetry is to make the wavefunction a function not of a global time parameter, but of the chosen spacelike 3-surface we designate "now." But it is no longer so crystal clear that it is simpler than the Bohmian version. We've eliminated some complexity, but then we've added additional complexity back.

Consciousness is a mechanical process, so anytime a computation takes place that represents thinking, there is thinking going on.

If we assume for a moment that Bohmian mechanics is true and that we, the people who have proved it to be true, are that which is represented by the Bohmian particles, we still have left the uncomfortable question of what to do with all the other people, encoded in the pilot wave rather than the particles, who, according to the correct representation of the computation taking place inside the pilot wave, have convinced themselves that they've all proven that many-worlds is true.

Bohmian mechanics claims to answer that question by postulating that only the particles are real. But the pilot wave is real too, in some sense, it has to exist to guide the particles and satisfy Born probabilities. So all people believing themselves to live in many-worlds are real as well.

We measure bit 1 and put the result in bit 2:

We measure bit 1 and put the result in bit 3:

We measure bit 1 and put the result in bit 4:

>"consciousness causes collapse"

This is not a valid interpretaion of quantum mechanics. You cannot add "magic" to shit and call it an interpretation. That is not the way science works. Once you add "magic" you are not doing science, you are just trying to justify some shitty religion you believe in.

What you are talking about is new age bullshit. It is laughable, not science, and not physics. It is in no way a dominate idea in physics. The overwhealming majoirty of physicist have rejected it as fucking retarded and nonscientific. I'm sure there are a few retarded scientists who believe it, just as there are a few retards who believe in the creationism too.

A few crazy supporters in no way gives legitamacy to this fucking stupid idea.

You are introducing an unquantitative concept into physics.

You can't fucking do that, that is not science, not physics, and doesnt make any fucking sense.

Should we introduce "love" into quantum mechanics too. We can't rule out "love" right? What about god, should we introduce god into qunatum mechanics? we cant rule it out right?

love and god are not correlated to collapse.

but observation very clearly is. we can only demonstrate that a collapse occurred after we are conscious of it. that is indisputable. that's solipsism, which you have to agree is absolutely true, but it's a no go position and we need to make assumptions if we are to move forward. the question is how much out on a limb are we comfortable going from this tautology.

>> No.3165595

first of all, the ENTIRE UNIVERSE seems like a huge unnecessary complication, when all we can be sure of is our own consciousness. if a child says they saw a monster, we say it's more likely they were imagining it rather than a monster actually existing. same goes for the complexity of the universe.

next, observer effect plays as much a part in classical mechanics as it does in quantum mechanics: not at all, and absolutely yes at the same time. the schrodinger equation has as much "consciousness" written into it as F=ma, particularly since the later is just a limit of the former and everything on the macro world obeys quantum in a classical (hbar->0) limit. it's the *interpretation* that includes the consciousness, and this is the simplest interpretation possible.

The schodinger equation has no consciouss observer. Not even the fags who believe in conscious observers claim so. That is not where they say the conscious observer comes into play.

Read the post that
>>3165292
was referring to. It had nothing to do with CCC. There's no special role assigned to the conscious observers in the argument except for the fact that their observations need to be accounted for. The argument is "how can you claim that the other worlds don't exist when there are people in them?"

As for CCC, I find it unlikely, but I'm not going to automatically assume it's wrong just because you think it sounds like magic. It's not a fully-developed theory of course, because we'd need to figure out exactly what constitutes "consciousness." But we know consciousness exists, and I think you'll agree with me that whatever it is, it's probably not "magic."

Fail, wrong, thank you come again. There are perfectly good interpretations which actually make MORE sense and don't have any of this loopy consciousness causing collapse of the wavefunction being inserted forcefully into my anus.

Look up the transactional interpretaion or De-broglie-bohm interpretation of quantum mechanics, they're far more sensibl. And in those interpretations the universe actually exists when not being consciously observed! How astounding.

The transactional interpretation is even more vague than CCC on some rather crucial points, such as:
* Under what circumstances does the wave function collapse?
* How the hell do you compute this "standing wave" from the advanced and retarded wavefunctions?

If you like retrocausal interpretations, there are much better ones out there.

It's called the Correspondence Principle.

In the limit as hbar->0 (another way of saying large quantum numbers), the commutator of x and p becomes zero and you get classical behavior.

How to get a force equation from an energy equation? Have you even taken an undergraduate course in Hamiltonian and Langrangian mechanics?

The wavefunction never collapses, everything which interacts with that quantum system becomes 'entangled' with it, it becomes a part of a bigger wavefunction.

As for the computations, I have no idea, but if this interpretation doesn't actually affect the resultant values then I would presume they would follow the standard methods of calculation in QM.
