Is it possible to measure the speed of darkness?
Is there a difference between the speed of light and the speed of darkness?
How do you identify scientific text?
Is it possible to measure the speed of time?
How do you identify a scientific problem?
Darkness and light are scientific concepts? Or literary concepts?

Is it possible to measure the speed of darkness?
darkness is a visual property of an object
Visible light is an invert proportional to the opposing force
darkness and visible light are not properties of space
darkness does not have a speed

"darkness is a visual property of an object" Not necessarily
"Visible light is an invert proportional to the opposing force" meaningless
"darkness and visible light are not properties of space" Not necessarily
"darkness does not have a speed" Correct.

Darkness is the absence of light.
- If you turn a light off, the photons continue away from you at the speed of light.
- Behind the last photon there is darkness.
- Because the last photon travels at the speed of light, you could also say that darkness also travels at the speed of light ;) .
This is actually very important in telecommunications, because we turn laser beams on and off billions of times per second to transmit all those Youtube and Netflix videos around the world (other sources of entertainment do exist).
- If the darkness travelled at a different speed from the light, the signal would be badly scrambled by the time it got to the destination, and the data would not be recoverable.
That just leaves us with a few other problems, for example:
- Different wavelengths of light travel at slightly different speeds through optical fiber (it is a dispersive medium)
- A pulse of light consists of slightly different wavelengths, which arrive at slightly different times, which muddies the received signal
- So you could imagine that the darkness following (say) a long-wavelength photon travels at a different speed than the darkness following a shorter-wavelength photon(!)
- For really long-distance and/or high speed optical fibers, you can use a short length of optical fiber with the opposite dispersion from the main fiber, so that the slower photons catch up with the faster ones, giving a clean signal.
See: https://en.wikipedia.org/wiki/Dispersion_(optics) (https://en.wikipedia.org/wiki/Dispersion_(optics))
As telecommunications moves to increased speeds (above 25 Gbps per wavelength on optical fiber), lasers have trouble switching on and off fast enough. These faster speeds are moving to phase modulation of a carrier.
Ironically, this is essentially the same technique used in dial-up modems running at 1200 bits per second on telephone wires, in the 1980s (1200 bps = 0.000001 Gbps).
Darkness and light are scientific concepts?
Yes, they appear in science and technology - but we usually try to measure them in terms of spectrum and intensity.
Or literary concepts?
They have certainly been used metaphorically in literature and religion (as well as interior decorating).
...Just made it a bit more apparent that I was joking...

No it doe's not,. darkness is not a property of space.

The correct answer is that darkness does not have a speed, the speed involved is the motion of the light source and the shadow that happens when light is gone.

Darkness and light are the names of natural knowledge.
Man translates natural knowledge into a physical concept.
The light is translated into a geometrical point moving at speed C.
The darkness has not yet been translated
It is not certain that the translation matches the physical truth.
Shape, rough, cold, hot, are the names of natural informations.
All science is based on natural knowledge.

natural knowledge.
What other sort of knowledge is there?
-
Man is born and knows, and he knows that he knows.
Knowledge is inherent in the whole universe.
The stone knows how to fall, and the star knows how to move.
Knowledge realizes ideas of the universe.
The universe is not mechanical.
Any explanation of the universe must come to a miraculous idea.
Passive time is a miraculous idea.

Would you like to try focusing on answering the question, rather than writing 7 sentences?

Its about time for TNS forum to embed a Philosophy section. 👍
I don't see any valid reasoning against it.
Why should our fellow philosophical members feel left out, any living self-conscious n self-aware organism has the right to philosophise. ✌
