Single-slit and double-slit experiments are cases of light being curved. Let us consider that light appears to travel at c along this curved path. Suppose that a photon appears to travel a curved distance of d and hits a screen. The time value at the screen along the curved path is the same time value at the sender. However, due to 1/c invariance, from any perspective I will see the time difference between sender and screen according to straight-line distances. That means that the length-time that I observe or measure between sender and receiver is smaller than it is measured along the "instantaneous" curved light path. In other words, the photon has shifted into a slightly different time than the one I can observe.
However, this also suggests that I wouldn't see any photons hitting the screen, because any curved path would mean a slight shift in time. This suggests that the light event is not instantaneous after all, but has a small duration. So, though many photons appear time-shifted, those that are shifted only slightly are still visible. An interference pattern becomes apparent, as photons are shifted out of visible time to form dark spots, and others are shifted into visible time to form brighter spots.
A natural correlation between the energy and duration of a light event is that the duration of the event would be proportional to its energy. The apparent frequency of light might be illusory. An explanation of redshift or the appearance of it would need to be provided in accordance with TDR. Note that the appearance of a sinusoidal aspect of an apparent "light wave" may mean that a light event occurs similarly sinusoidal. That is, it is a "flash" of light energy that begins "dark", increases in intensity until a maximum amplitude is reached (would the amplitude be the same for all different energies of light?), and decreases back to "dark". If a light event is said to occur at a specific time, it would likely make sense that the moment of maximum intensity would be that time. Note: Several questions come up that cast doubt on this interpretation of frequency effects of light. Does that mean that part of a light event can happen before the official time of the event? Wouldn't it make more sense if higher-energy light stretched it across space (width, for example) rather than time? Either would allow wider bands for higher frequencies to be visible in the slit experiments, but the opposite effect is apparent. Therefore these ideas need to be revisited.
The effect of "which path" observations on the slit experiments destroys the appearance of interference. A couple possible explanations come to mind:
- The detection of light anywhere along the path changes the light event from a single curved-path event, "splitting" it into multiple straight-path light events.
- The detection of light involves an interaction with matter. That matter has size, which means the interaction takes time. This time might be random enough that it removes the otherwise precise correlation between time and locations on the screen.
Revisiting the Time-shift explanation for interference patterns...
Consider conservation of energy as it relates to number of photons. We would think that any photons that "disappear into another time" would be replaced by an equal number that appear from another time. However, a single-photon light-event will always be detected. So something is wrong.
The model of a single light event is a line (possibly curved). But the double-slit experiment suggests that light propagates as a spherical wavefront.
It could be that light does indeed propagate along that entire round wavefront, and in fact interacts with the entire area it "sees". However, every location that it interacts with exists in a different time, while any observer only exists in a single time. An observer will see light interact with only a single point at which its observed time matches the light event's time. An observation from the exact location of a light sender, could "see" that that light in fact hits everywhere, and not just a single point. This reinstates the instantaneousness of light.
It also suggests an experiment which may predict that observers in frames that have relative movement will see a different diffraction pattern, because each observer will have different measurements between the light source and locations on the screen. However, it could instead be that the pattern is defined by the ratio of curved-path distance to straight-path distance, which might be the same for any observer.
There must be something that was missed or incorrect in all this speculation.
The above describes single-slit interference, but doesn't cover double-slit.
One last wild speculation: What if time is meaningless to a light event? The "time" at which it occurs depends on a definition of time, which is time-frame location dependent. Perhaps the light event exists as a wave through all of time, and we only see the single location and time of that event that matches our observed time-frame's time definition of that event. In this case, when a single photon follows a curved path, we see it shifted in time depending on location and straight-line distance between sender and receiver. So with less curvature, we observe events similar to if they were straight-line light events, and at locations involving more curvature, a photon appears to disappear into another time, and elsewhere we see more or less (depending on location) that the photon is visible as it appears due to it having been sent at a different time value than the one that our time frame says it was sent at.
Confusing.
