Could you point to some articles on this? It's way outside of my field, but it sounds very interesting.

This is cool IMO (2016): https://www.youtube.com/watch?v=nRSBaq3vAeY Apologies if its considered off topic - I see double slit experiment and I always think of this. It blew my mind.

I'd be curious to hear what happens with a fake tone or indicator.

I would expect that to decouple the experimenter to the experiment and should result in no change to the output.

Crackpot vibes

Where did he go wrong in the experiment?

Amusing to see all the pessimistic comments form programmers who have zero understanding beyond high school maths thinking somehow there is a magic solution to all the problems in physics like you can just refactor everything. Quantum field theory is definitely not stuck in the 1920s. Modern physics has a lot more going on than 19th century mathematics. We understand quite a lot about the mathematical structure under…

Hey- can you please not post supercilious or sneering comments? It really poisons the ecosystem. What we want is curious conversation in which people share information. Putting others down who you think aren't as smart as you or others, and calling that "amusing", is definitely not what we're looking for—no matter how wrong they are or you feel they are. This is in the site guidelines: https://news.ycombinator.com/newsguidelines.html.

If you know more than others, that's great—the best thing is to share some of what you know, so the rest of us can learn. Just please do it without swipes and putdowns.

I come to HN to learn new things in fields I know little about, like tech and computers, I always find the comments to be authoritative and interesting. However, whenever I read the comments on any subject I happen to know something about, like physics, they are always completely nonsense from people who clearly have absolutely not even the smallest amount of experience in the area they are talking about. The worst p…

name and shame, so those of us non-experts can spot the bad comments.

Please correct wrong information without shaming others. We're trying to avoid the online callout/shaming culture here.

How is this: The electron loses its energy as it approaches the final destination, this energy (of wave nature obviously) passes through the slits and forms interference pattern.

I know that for every problem there is a solution that is simple, neat—and wrong. And above proposition is most probably the same. But still I'll be glad to read the answers.

(Disclaimer: I'm a novice)

Yes, but go back to philosophy not math. All the evidence suggests the "particle" interpretation of QM is simply wrong, that light or energy really is just a self propagating wave, which explains the double slit experiment cleanly, and is not incompatible with energy levels or quantization if formulated correctly. Experiments that claim to show light consists of particles need to be reassessed wearing a philosopher's…

No. "Particle" and "wave" are analogies. They're not even wrong, because they're not descriptions of what actually happens. The real problem is we don't have an analogy for what actually happens, because - by everyday expectations - the traditional interpretations are beyond weird. And the more recent interpretations are even weirder than that. It's likely - after Bell - that there's something non-local happening. An…

you mean we live in a simulatio n ?

As former quantum physicist, I find it little troubling to read "quantum theory has reached a dead end" in specific reference to the interpretation of quantum mechanics. Most quantum physicists could not care less about how quantum mechanics is interpreted when it makes highly accurate quantitative predictions, and there are still plenty of interesting open problems for quantum theory (e.g., related to the practical…

> namely that the measurment problem is solved by decoherence

I think "solved" is too strong. The Wallace paper you reference, for example, does not claim that decoherence solves the measurement problem. His claim is only the more modest one that understanding decoherence helps to clarify what the measurement problem actually is.

As former amateur physicist, who read a couple books over the years :)

To me it's quite simple. We haven't detected what is causing the waves that the particle of light is riding on. The particle of light is like a surf board, riding a wave and will always hit the shore in the interference pattern. Einstein and Bohr were both right.

What has been the wrong assumption over the years is that the light is generating the waves. It seems obvious to me that something else outside of the light (that we haven't detected yet) is generating the waves.

My amateur physicist guess is the waves are generated by the clock cycles of the computer simulation we are in. All computers require a clock to function. Why would our universe be any different?

I find it kinda hilarious that you all seen to be discussing some sort of cutting edge or controversial idea called "quantum theory" or "quantum physics", when I have to assume you're taking about century old theories of quantum mechanical systems like ones that continue to help design the electronics that you read this piece of shit article on.
