quote from the above linked article: Heat typically travels through three main pathways: conduction, convection and radiation. Conduction describes heat transfer via direct contact of materials, whereas convection is heat transfer arising from motions of gases or liquids, like hot air rising. Those two don’t apply for empty space. But radiation — heat transfer via electromagnetic waves — can occur across a vacuum, as in the sun warming the Earth. Now, the researchers say they’ve experimentally shown another mechanism by which heat can make it across a vacuum, though the effect is significant over only very small distances.

Correction to the above highlighted quoted text: .....not another mechanism but the ONLY MECHANISM!

Hello Emmanouil:

Excellent to start Question on that article that I sent you recently. It will eventually prove what we're proposing "Magnetic quagmire aether". Quantum jitter is an essential phenomena associating that medium.

We'll be able to show eventually that magneton, fundamental primary element making up electron link all of space!!!!!

Thank you with everything ongoing.

Sincerely,

No, they didn't. Quantum jitter is just a term that attracts clicks. It's well known that electromagnetic waves transport energy and they can do this through a vacuum. So they can transfer energy to some object, which means heat it up; so if there are two objects that are at different temperatures, in vacuum, their temperature difference will diminish through radiative transfer.

Nothing particularly exciting conceptually; if the object is such that its quantum properties are relevant, then the experiment requires some extra care, that's all. It's keeping track of the quantum effects that depend on the objects, that's of interest.

The experiment is of interest, not the theory, that's known for decades. What's nice is that it's now become possible to actually do such an experiment.

Indeed the interest of the experiment is that it doesn't involve travelling electromagnetic waves at all; it relies on the fact that the presence of the two objects induces fluctuations of the electromagnetic field in the vacuum in which they are placed, that excite the elastic deformations of each object and it is these deformations (that are superpositions of objects called phonons) that describe the variation in the elastic deformations, therefore the temperature variation. So it's the standing electromagnetic waves that are relevant here. If there is a temperature gradient-as is the case here-it will die out and the claim of the paper is that they can exclude that it does so through radiation, which is the background to the signal they claim to have detected.

The popular article has too many misleading statements for it to be of any use. the technical paper https://www.nature.com/articles/s41586-019-1800-4.epdf?referrer_access_token=-KRxVNWxhiZeeuB8hVnV2NRgN0jAjWel9jnR3ZoTv0OXGOLOoy3qAr8mWu0MJfSkJf7kKBKV5WctCdlvk6YT5rqPpWXoq12FkAtSGAIRc0iW-5b0FyOqMOVhbrPELnE_PLTtKfknVvdfNSu3MGcwewxjK7-svPovP829wxKIKtKTURNR1rCkydaZYksueFnXLpV-zUNi6pR-ox5XXjh8q82KngW7BxKNnwJl52VfD9pbZl1Ul1Pv3-77u4YnN87LyH2KmWTVJiuOkrMaMMHT4A%3D%3D&tracking_referrer=www.sciencenews.org

is more relevant; though it's by no means obvious that they did do what they claim to have done, since just how sure they can be that they've excluded radiative transfer isn't clear.

Stam,

Thanks for the separate link to the nature original article although it was given also inside the journalist science news report of the research. A better science news report of this research can be found here:

watch also the video inside the above link.

I believe you are missing the point here. This particular experimental research is more significant than one things. They are using the Casimir effect to experimentally prove vaccum space to be a medium for photons transmission due the matter carpet created by the ever present zero-point quantum fluctuations virtual particles thus quantum jitter which anyway strongly infers that vacuum space is not empty but a medium. They just used the Casimir effect to amplify the effect and prove their point.

I don't agree with your standing waves explanation (not for the Casimir effect but relating the heat transfer) since this requires two end termination of least L=λ/2 and with infrared radiation starting at 700nm wavelength they went far below that point as less as 10nm distance between the two membranes. So there were no standing infrared waves and besides we know that standing waves can not transfer power.

I don't believe that EM waves radiation thus photons transfer is possible in the far field without the presence of electrons in the near field to relay them? After all light is a matter-medium phenomenon. The travel of light waves over relative long distances without the presence of matter is ridiculous an outdated dogma.

As I have shown here:

Preprint Why electromagnetic waves propagation in vacuum space is inf...

The absence of electrons in the near field would result in EM waves dissipating as normal static magnetism with the inverse cube law with distance and even worse up to 1/(r^5) depending the distance and not the inverse square with distance as EM waves do. Meaning long range astronomical distances of light travel not to be possible and night sky on Earth would be completely dark, no stars.Electrons must be ever present along the way so that light can travel relayed and cascaded by one electron to the other in their near field.

Quantum jitter of vacuum space with the virtual electrons popping all the time in existence provide the means and carpet for an EM radiation source signal to be possible to travel in outer vacuum space dissipating with the inverse square law with distance for the far field.

I agree with you that they fail to adequately and unambiguously explain in their research how they distinguish and control experiment their quantum jitter travel of EM waves from the normal EM waves inverse square law with distance radiation.

I couldn't find what the dissipation rate with distance was of their EM infrared waves Casimir experiments? I guess if they increased the distance beyond 400 nm the thermalization process between the two membranes stopped but that would mean that also no normal EM radiation was possible after that distance. Dissipation becomes too large with distance for their small energies involved in their experiments only 300K.

So how they distinguish between these two as the claim heat transfer EM radiation modes, the normal EM radiation and the the Quantum jitter transfer mode of EM source signals?

The total lack of the authors to compare these two modes of EM radiation as they claim tells me that they silently tell us that there is actually only one mode of EM radiation possible in vacuum space, thus due the Quantum jitter of vacuum space providing the necessary medium for light traveling.

When Planck, and later Einstein, introduced the 𝐸=ℎ𝑓 formula , their conclusions were based on the interaction of light with matter at atomic and molecular scales. However, light–matter interaction fundamentally depends on the size of the receiver—effectively, the antenna. For efficient power absorption, the receiving antenna must typically be smaller than the wavelength of the incoming radiation. This is why 𝐸=ℎ𝑓 appeared valid when applied to sub-micrometer structures such as atoms and molecules. From an electromagnetic standpoint, these were effectively tiny antennas, smaller than the wavelength of visible light. But such antennas are inherently incapable of detecting radiation at millimeter or longer wavelengths. Therefore, the justification for 𝐸=ℎ𝑓 was rooted in a test setup that did not account for scale and wavelength limitations—calling into question its universal applicability. Despite this, the formula has been treated as foundational and even incorporated into the derivation of the Schrödinger equation. It is possible that some of the shortcomings of Schrödinger’s equation stem from this questionable assumption.
