Or, by doing the same test in different ambient light intensity.

I'd expect this to progressively dim parts of the image on the retina. But why would they move? (If they in fact do.)

The following test might distinguish between an optical effect and an optical illusion. Instead of the finger or pencil, try an object that is of the same color as a background, i.e., something white, maybe just a piece of paper. If it is an optical illusion, the phenomenon will disappear. If it rather is an optical effect, it will be the same.

Well, congratulations.

Optical illusion, akin this?

I suggest moving this thread to the Speculations forum.

I also had once my hair in a solid crust, unrelated to ice. Back in Baku, after swimming in the Caspian Sea. It was a blob of mazut. Evidently, I swam through it. Caspian Sea, especially around Baku, was heavily polluted back then, as the main source of oil in the USSR was there.

The clocks that measure time without measuring a movement which have been considered so far: 1. A mean lifetime of decay of an unstable elementary particle. 2. A mean time of flipping of electron spin in a magnetic field. Here I propose another: 3. Change over time in a wavelength of photons of the CMB.

It looks like being out of focus is a requirement for this phenomenon. Perhaps, there is a key for its explanation.

What components are they? Here is the composition of the atmosphere we breathe:

Yes, diffraction does not seem a correct explanation. Can it be tested? (I didn't succeed to reproduce the effect so far. Without glasses I can't say what's happening, while with glasses nothing like that seems to happen.)

To the contrary, from the muon's perspective time passes from its "birth" until its "death". Its mean lifetime is about 2.2x10-6s in the muon's frame.

Muon decay is not an emission of particles from muon. Rather the muon disappears, and other particles appear. Here is the diagram:

They change when they decay, but there are no: PS. When muon decays there is no muon anymore.

Does it happen if you replace the finger with say a pencil, a chopstick, etc.?

It is noticeable and very well quantifiable in GPS, for example.

I had in mind radioactive and particles decay. Another example of a non-positional change could be electron flipping spin in magnetic field. That happens when frames move wrt each other at any speed, and in any strength gravitational field.

In all studies of sciences, I've never heard that time is a thing. Evidently, this part of the OP article is a straw man fallacy. On the other hand, contrary to the OP article considering space and time together is not arbitrary but rather a necessity because space and time are related: what appears as time for one observer appears as space for another. Another claim of the OP article is that any duration measurement necessarily measures a movement. This is not so as there are processes that have duration without a movement such as decay. This processes in principle can be used to measure time.

You will.

It does not matter which gas we are talking about as long as this gas causes narcosis. Nitrogen is such a gas, that is why I mention it. Oxygen is not. A gas that causes the narcotic effect has a saturation level which depends on the air pressure and the tissue. When this level is reached, it does not matter anymore how much of the gas enters the body. It exits the body at the same rate as it enters it when tissues are saturated. The breathing rate does not affect the amount of the gas in the tissues anymore. The breathing rate increases with exercise because the tissues use oxygen and need more of it. Oxygen level never gets saturated because oxygen is used by tissues. The narcotic gases are not used by tissues.

What accumulation? Our tissues are saturated with the nitrogen at the saturation level for atmospheric pressure and breathing - more or less - does not change this level. That is, breathing more does not increase the amount of nitrogen in the tissues and breathing less does not decrease it.

In my early teens, I flew from my warm southern city of Baku to Moscow first time, in winter. I remember a shock of the first breath when I got out of the plane. I simply couldn't take it. My nose was shut with ice.

Sorry, I don't want to interrupt the discussion, just to notice that I got exactly the same "diagnosis" many years ago soon after moving to a new country. My complaint was an abdominal pain. Later it turned out to be an allergic reaction to coconuts.

My last point has not been addressed, i.e., The point 6 in the OP is: but I don't think there is a similarity. Moreover, the "Narcosis while diving" does not appear until the air pressure gets above 3 atm. It is nowhere close to variations in atmospheric pressure in all other conditions mentioned in the OP article. It is also nowhere close to atmospheric pressure when people sleep.
