TC: the light you observe between your eyes and an object in the spacial volume is not visible
Randwolf: To say this another way, "the light that you observe is invisible" - is that correct?
TC: Unless interacting with matter or medium. Like a laser in a vacuum hitting a left over dust particle, we would not see the beam it is invisible to us , but when the particle interacts with the beam we see the particle in the light, lit up by process.
Randwolf: ''OK, so would that be an axiom? Have we established clearly that you can only observe invisible light?''
TC: It is an axiom that you can not observe light in an empty space, you can not observe it because it is invisible.
That's very odd, TC, that you would say "you can not observe it because it is invisible". You know why I think that is odd? Because you earlier said "the light you observe ... is not visible". How can the light that I observe be "not visible" and yet I "cannot observe it because it is invisible"? Is "not visible" different than "invisible"? Or does "visible" = "invisible"?
TC: You observe a clarity of light that passes through the air , it is an opacity to sight, a value of zero spectral magnitude to sight, an equilibrium to sight.
Randwolf: ''Does any light have a spectral magnitude that is not zero?''
TC: Yes , any light that is in interaction with matter or a medium , the spectral values .
Randwolf: ''So all light has a nonzero spectral value when it is in a medium or when it strikes matter, is that correct?''
TC: NOT CORRECT, the other way around, light has a spectral value of zero when not in an interference stage.
That's very odd, TC, that you would say "light has a spectral value of zero when not in an interference stage". You know why I think that is odd? Because earlier you said "You observe a clarity of light ...[with]... a value of zero spectral magnitude". How can I observe light with a "a value of zero spectral magnitude" when "light has a spectral value of zero when not in an interference stage"? Wouldn't that mean I can only see light that is NOT "in interaction with matter or a medium"? Or is a spectral value of zero = a spectral value of NOT zero? As in 0=1? Is that what you are saying TC, that 0=1? You've said it before, no reason to back down now...
I am pretty sure I read somewhere that snakes use infra red to see at night.
Maybe, but then wouldn't snakes think that it was dark if they were placed somewhere that had no infrared available? So without light and / or infrared that particular species would agree that it was dark, right? Doesn't that contradict your earlier statement that "Other species that if they could talk, would think you was insane if you said that it was a dark night. They would argue it was always light outside." -
always light outside - yet a snake would not think "you was insane if you said that it was a dark night", so long as there was no infrared energy about. Agree or disagree TC?
