I've watched the videos, but they were just ramblings without any physical or mathematical substance.

Nope! We can detect individual photons (and measure their properties) and a mirror can (nearly) perfectly focus and collect every photon that hits it. The frequency of detection events would change with the distance, but the frequency doesn't hugely matter, one photon per week is enough for science!
It is definitely possible that I’m missing something here. But, for example, if we are trying to get an image of a dinosaur, and we’re only getting one photon per week, how’s that work? The dinosaur should have moved before the second photon is sent off, right?
Re: Time Warp: Delayed-choice quantum erasure
#74I appreciate this article, as I agree with the author that the delayed-choice quantum eraser is a misnomer due to ignoring what we now know of quantum states. It's really frustrating learning modern quantum mechanics but then reading about the delayed-choice quantum eraser making conclusions from an older understanding. However, I still haven't seen anyone do the math about it. It shouldn't be too hard to keep track…
I don't think it has anything to do with what we know "now". It's just paying attention to the fact that the signal photon hitting the screen causes a collapse that affects the state of the idler photon. Which then explains the data via the collapsed state depending on the position of the hit, and one of the possible idler measurements being in a basis perpendicular to those variations. All quantum interpretations gi…

While I appreciate the blog post, it seems a bit disingenuous. I hope everyone understand that if you take two entangled photons A and B and detect A before B, then the outcome of the measurement of B must depend on the outcome of the earlier measurement of A, bec…

I'm sorry but the chat format is a really poor way to share ideas. It's long, meandering, and contains many instances of wrong and not-even-wrong assertions by you (expected, you don't claim to be an expert, but hurts your credibility) and by chatGPT (expected, hallucinations, but makes it impossible to believe any assertion without already knowing what makes sense). If you believe you came up with something worth sh…
You're totally right that I am not a scientific expert on this by any means. But often, breakthroughs in science come not from orthodoxy or experts, but exactly the people who don't believe in the orthodoxy. https://en.wikipedia.org/wiki/Planck%27s_principle Examples include: Einstein's theory of relativity vs luminferous ether orthodoxy Rutherford's discovery of radioactivity vs the 100 million age of the earth orth…

Generally for QM entanglement experiments you can't interpret the result without the measurements from both sides. So while you might be able to demonstrate after the fact that impacts on the state of the system propagated faster than light, you will not be able to make use of that FTL propagation in any directly useful manner.

Modern quantum error correction techniques are dramatically improving:
Decoherence suppression: Extending coherence times of qubits.
Fault-tolerant quantum computing: Reducing errors in quantum state evolution.
Quantum memory storage: Holding quantum states stable for long durations.
So if decoherence is controllable, and if randomness is epistemic (not ontological), then this suggests we can gradually influence quantum measurement probabilities.
Look, here's what we can already do today:
Extend entanglement coherence times (already happening).
Control quantum noise with precision (e.g., superconducting qubits).
Perform weak measurements without full collapse (experimental quantum optics).
I agree that directly biasing entangled measurements nonlocally has not yet demonstrated today, but it could be in the near future, which is what I am predicting can unleash this FTL communication possibility!
Quantum error correction is already proving that decoherence isn’t truly random—it can be controlled. The interaction-free measurement paradox suggests that it’s possible to extract information without collapsing a wavefunction. Bohmian Mechanics & PWT are underexplored experimentally, and this would be a direct way to test them.

This is a depressing comment to me. Solving this problem is not just about "Math" and he explained it in the videos. The current math is based on a flawed premise, that time continues when there is no movement or change.

Does that mean quantum calculations are just a fancy way of describing correlated probabilities, and have nothing to do with spooky action?
