That's literally claiming light is magic.
I'm done here. Peacegirl, no. Any number of photons greater than zero in quantity is enough photons to carry inference.
When one photon is not enough to trigger the sensor switch of the telescope, we in fact pass that photon through a laser substrate of some kind. This is a material which is charged in such a way that photons of certain bandwidths *excite secondary parallel photon releases* in charged atoms they hit.
Usually with space telescopes a charged ruby is used, and it is a microwave bandwidth photon that is usually amplified; at short cosmic distances, microwave radiation interacts with less of the space dust, and at large distances even hot things attenuate to microwave spectra.
Anyway, the ruby gets hit with a single photon and is transparent to it, except for the fact that some bit of the matrix has just enough energy to be released without drawing ANY energy from the passing photon that strikes it out of the electron shell. One photon goes in, two identical ones come out.
The overall quality of photons does not "diminish", only their probability of reaching the other end.
Light has a rate of motion. It is well and truly studied the process by which light is produced, reflects/refracts/shifts, interacts with a receptor dye in the eye, converts that interaction into a signal on a neuron, and then this signal gets processed, such that the thing your perceived yourself seeing happened *in the past*.
That's where the author disagreed. You say that the process is well and truly studied. Converting the receptor into a signal where that signal gets processed, such that the thing you perceived yourself seeing happened is "in the past" is a theory as to what the brain does.
And his disagreement is why he is wrong. We have
fully and completely observed the process.
That theory has been borne out by observation of the phenomena and process happening, if not all at once, in each of the specific characters of interaction.
We observe the photon hitting the dye. We observe the dye having it's structure changed electromagnetically, we observe the dye exciting the neuron under it. We observe the neuron changing state to fire.
Once we have observed the mechanism of the eye, it is trivial to compare the action of one mechanism that generates nerve pulses to another (these are the same mechanism at this point). At that point all you need to do is compare the action of neural groups in general on neural signals to know what neurons do with signals.
This is why you are so hopelessly wrong about the implications of decoding a fly brain to understand how brains process signals, because we have isolated that it's "signals" and "processing" happing of both kinds of eyes, and both kinds of brains respectively.
I have in the past said that the past cannot reach out and touch you, but I suppose this is untrue. It can, but only at the specific range where it's past is still your present.
You say one's past can still be one's present if it's at a specific range, which cannot be true when the past has no existence other than in memory.
You are mixing modal scopes badly here. Please stop that.
