Or perhaps you just don’t know how any of this works. It doesn’t fit with your mental model of what’s going on, but it’s your model that’s wrong, not the experiment. (iow this is argument from incredulity, which is a fallacy; things aren’t wrong simply because you don’t undertand) The light passes through the cube. Straight through for one polarization, at 90 degrees for the other. Which path it takes tells you the polarization. All you have to do is put a photodetector at each path to tell you where the photon went.

So does USNO, via GPS. Time from USNO and NIST typically agree to better than 100ns (often much better); there’s a memorandum of understanding that dictates how well. How is this different from other base unit standards, like length, which is defined in terms of how far light travels in a second? They’re all conventions.

Directional charge? Charge is a scalar. ! Moderator Note Piling nonsense on top of nonsense, and repeating assertions instead of addressing issues. A hand-wave is not a model. We’re done here. Don’t bring this up again.

! Moderator Note The next step needs to be addressing the many problems that have been pointed out, rather than building on top of a flawed foundation

! Moderator Note Stock discussion is decidedly not quantum theory.

But without the BH, there is no appreciable gravity. Certainly not enough to do what you claim. And: a dipole? What would the electric dipole moment be?

Depends on the experiment, but you know where the photons are coming from and the wavelengths, so it’s not difficult to do. It’s a cube, 1/2” or 1” on a side. Exactly. And that’s why you need statistics of several photons, as you pointed out.

You’d probably send the light through an optical fiber, which can be coiled up, and the measurement takes much less than a second. Because you entangled the photons. As you’ve been told, if it’s just a random photon there’s no way to tell if it’s entangled Again, as you’ve been told, you need multiple photons to do this. You really need to read the replies in the thread.

Because that’s trivially known, if you’re familiar with atomic physics. Your tone suggests that you think it hasn’t been done. I’ve done it. One way is to send it through a polarizing beam-splitter cube. If the polarization is in one direction it goes straight through. If it’s orthogonal it gets reflected. Knowing which way it goes tells you the polarization I have no idea of the context of this question, but spacetime means you’re talking about relativity, and entanglement is a quantum effect. So you need to explain the connection.

The issue that’s all to common is that interested amateurs watch a video but it’s not saying what they think it’s saying. Saying that the whole lecture is fascination isn’t the issue here - what is in the video that pertains to this particular discussion. It’s unlikely that all 50 minutes are.

It’s unreasonable for you to expect anyone to watch a 50 min video and sort through the arguments, which is why we have a rule against it to add to this: measuring one photon doesn’t even tell you it’s entangled It could possibly rule out entanglement, since the correlation could come out wrong. But that’s it

You can ask questions of the original poster as long as it’s on-topic

Entanglement can’t be used for faster than light communication, which is the usual proposal

The first two responses gave some details of what cosmology says on the matter

! Moderator Note And you have a thread for that, so we won’t be discussing it here

That’s just silly Source: me, who worked for ~25 years at the US Naval Observatory in the precise time department

But why would they stay in orbit if there is no longer a black hole? They tend to go in straight lines. LOL no. There have been experiments that yield a much smaller value

I prefer Rb-87, but that’s a personal bias. Some former colleagues like calcium and strontium How does this differ from length?

it’s a possibility that some want to explore. They want to find evidence for it, though Something has to have written and be running the simulation, if the hypothesis is true

You introduced it as somehow being a consequence of the notion of dark matter - you suggested it’s a clear connection. If it’s not your position, why bring it up?

How does this reveal anything about time? You can have static forces If you are doing work on an object (which requires exerting a force) the energy can increase or decrease in time

Radiation is heat if it’s coming from a thermal source, e.g. the sun’s blackbody radiation has a fair amount in the visible. Something cooler radiates in the IR ”yields are low” is a key phrase in the above description

To add to what exchemist said - at each step of using waste heat the medium is at a lower temperature, so you quickly lose the ability to extract work.

…and ? a dynamic field changes in time. What’s the connection?

I don’t know what “time is applicable on energy” means Energy is a property, not a thing
